Interactive Landscape Design and Application Effect Evaluation of Community Sports Park by Wireless Communication Technology

To improve the comprehensive quality of urban community sports parks and enhance the modern life quality of residents, first, wireless communication technology is discussed. Second, the construction of community sports parks and the concept of interaction design (IxD) are explored. Finally, a comprehensive assessment of the construction of sports facilities in the park is carried out. In the research method, a field investigation is carried out on the sports park built in Chongqing first, and the research content is designed according to the investigation results. Then, the current sports park construction results are investigated and evaluated by means of a questionnaire survey. The research results show that the five community sports parks in Chongqing still need to be improved in terms of their comprehensive construction. The most obvious in terms of their essential functions is the Yangtianwo community sports park, which has the lowest comprehensive score of 29 (total score is 60). Subsequently, in the comprehensive evaluation of community sports parks, Yangtianwo has the lowest satisfaction evaluation. Finally, in the evaluation of wireless communication technology, residents have the lowest satisfaction with Dashuijing community sports park, and the evaluation score is 20 (total score is 30). It denotes that the comprehensive evaluation of Yangtianwo is the worst among the five community sports parks. The research not only provides a reference for the construction of community sports parks in Chongqing but also contributes to the comprehensive development of community sports parks.

Using the environmental justice approach to evaluate equitable allocation of urban parks: A case study of main urban area of Nanjing, China

Urban parks have broad benefits in promoting public health of urban residents and advancing urban sustainable development. The equity of urban park spatial allocation has a great significance for maintaining environmental justice. However, the current researches on the equity of urban park spatial allocation still focus on the quantity and geographical equality but pay less attention on the equity of quality and accessibility of spatial allocation. Based on the approach of environmental justice, with the main urban area of Nanjing as an example, we comprehensively analyzed the equity pattern of urban park spatial allocation from the three dimensions (six parameters), including park accessibility, area and quality. Integrated analysis methods were adopted, including internet map service for accessibility analysis, subjective and objective comprehensive quality evaluation, spatial autocorrelation and non-parametric test. The results showed that the spatial allocation pattern of urban parks in the study area had obvious core-edge characteristics. There was a certain degree of inequity in park accessibility, area and quality, with a relatively significant pattern of environmental injustice. There were significant differences in the inequity of six parameters in the three dimensions, with the accessibility score and accessible park area showing the most prominent inequity. The minimum time required to reach the park and the quality of the nearest urban park took the second place in inequity. The quantity of high-quality urban park and minimum time required to reach the high-quality urban park showed relatively small difference. The average values of accessibility score, total area and quality of urban parks accessible to high-income communities were 3.7, 2.7, and 1.6 times that of low-income communities, respectively. The results indicated that high-income communities enjoyed better accessibility, larger area and higher quality in terms of urban parks. Middle-income communities enjoyed the most prominent advantage of green space, while most low-income communities were unable to reach a high-quality urban park within 30 min's walk. Our results could provide a decision-making basis and planning reference for the optimal configuration and rational planning of urban parks in China.

Entitlement, Indeterminacy and Professional Discretion in Urban Planning: Problematising a Child’s Right to Clean Air for Play in London

The interaction between air quality and play space receives less focus in planning than it has in public health and environmental sciences research. In this paper, seven local planning authorities of inner London (UK) were sampled from the 10 boroughs with the worst air quality in parks. Greenwich, with significantly better air quality, was included for comparison. The selected authorities were validated against deprivation data, ensuring variance in socio-economic terms. Across this sample, 21 major residential planning applications were assessed, alongside a document analysis of planning policy documents for each authority. Lastly, five semi-structured interviews with different practitioners collectively provided multi-disciplinary perspectives on the planning processes across the sample. Despite the national government having conferred children a right to leisure space and a healthy environment via international conventions, the English planning system, as an institutional rights framework, is not consistently prioritising the delivery of children’s play space nor delivering play space where the air quality has been robustly assessed. In other words, such rights have been subjugated to other priorities in limited urban space in London. Therefore, a discretionary planning system does not preclude individual human rights from becoming disadvantaged under democratically controlled decision-making processes.

Factors Influencing Earthworm Fauna in Parks in Megacity Beijing, China: An Application of a Synthetic and Simple Index (ESI)

Complicated factors in urban areas have been reported to impact the density, biomass, and diversity of earthworm fauna. Urban parks provide essential habitats for earthworm fauna. However, how earthworm fauna are impacted by park traits, such as construction age, distance to city center, visitor volumes, sizes of greenspaces/parks, and attractiveness, etc., still remains unknown. These traits are well characterized by the impacts of urbanization intensity and administration quality of parks in megacities. Therefore, 16 parks with gradients of construction ages and geographical locations in Beijing city were selected for investigation. Furthermore, an earthworm synthetic and simple index (ESI) for characterizing earthworm community has been developed to compensate for the lack of robustness by using single ecological indexes. The results showed that earthworm population density (38.6 ind/m2) and biomass (34.0 g/m2) in parks were comparable to those in other land use types in Beijing. Ecological groupings were dominated by disturbance-tolerant endogeic and deep soil-inhabiting anecic groups, and most of them were adults. The earthworm population was influenced by urbanization intensity, while the earthworm community composition, species biodiversity, and ESI were affected by administration quality of parks. The soil moisture and microbial biomass carbon were the key factors in shaping earthworm assemblages. ESI could be employed as an effective indicator in depicting character of earthworm fauna. This study highlighted the impacts of park traits on earthworms in urban parks. The variation in park traits that influence earthworm fauna was probably attributed to soil properties.

TOURIST PREFERENCES AND EXPECTATIONS OF URBAN PARK: A CASE STUDY IN KITAKYUSHU, JAPAN

The quality of an urban park can be evaluated by understanding the tourist’s reasons, preferences, and expectations. This study analyzes several variables based on answers to field survey questionnaires using 425 respondents. Furthermore, Green Park, located in Kitakyushu, Japan, serves as the case study. The result found six essential variables: 1) “Playing with children” is the most popular reason for visiting this park; 2) Tourists living closer to the area frequently visit; 3) The existence is necessary; 4) The relationship between the importance and the origins of the tourists is related to a sense of place; 5) Tourist preferences are affected by seasonality; 6) The most favorite expectation is the availability of water facilities. This further can contribute to tourism development in urban parks with similar climatic and environmental characteristics.

Optimization Strategy for Parks and Green Spaces in Shenyang City: Improving the Supply Quality and Accessibility.

In this study, we evaluated the supply quality of parks and green spaces within the Third Ring Road area in Shenyang city by combining a landscape pattern index analysis with a principal component analysis. Moreover, a network analysis based on the ArcGIS platform was used to measure the accessibility of parks and green spaces. The research results showed that the overall supply quality of parks and green spaces (−9.55) must be improved. The supply quality levels of the four analyzed park types could be ranked as follows: garden parks (118.00) > community parks (73.67) > comprehensive parks (−16.64) > specific parks (−32.17). Among the analyzed recreation parks, the accessibility of daily recreation parks was poor, while the overall service efficiency of weekly recreation parks was better, except in a few regions. These research results can provide suggestions for future green space planning in Shenyang city. In addition, from the perspective of landscape patterns, studying the service quality of parks and green spaces can provide new ideas for further research on accessibility.

Church Contextual Factors Associated With Latinx Physical Activity and Park Use.

Churches can be important settings for promoting physical activity (PA) among Latinx populations. Little is known about what factors across the church context-social, organizational, and physical (outdoor spaces)-are associated with Latinx PA to inform faith-based PA interventions. This study investigated associations of church contextual factors with Latinx PA. We used cross-sectional data from a Latinx adult sample recruited from 6 churches that each had a nearby park in Los Angeles, California (n = 373). Linear or logistic regression models examined associations of church PA social support, PA social norms, perceived quality and concerns about the park near one's church, and church PA programming with 4 outcomes: accelerometer-based moderate-to-vigorous PA (MVPA) and self-reported adherence to PA recommendations, use of the park near one's church, and park-based PA. Park quality and concerns were positively associated with using the park near one's church. Church PA programming was positively associated with park-based PA. None of the factors were related to accelerometer-based MVPA or meeting PA recommendations. Findings suggest targeting church PA programming and nearby parks may be key to improving Latinx park use. Church and local parks department partnerships may help enhance park conditions to support churchgoing Latinx PA and health.

Estimating Willingness to Pay for Recreational Services of Public Parks

The study aimed to estimate the benefits derived from the park to whole society and identify the socio-economic determinants of willingness to pay (WTP) of public park visitors. The estimated Poisson regression analysis result showed that the visit rate of the visitors was significantly predicted by their round-trip. Likewise, as per the regression analysis output result proved that various variables like income level, age, years of schooling and dummy variables perceived park quality, place of residence, sex and employment status of visitors and average stay hours in the park significantly predicted the WTP of the respondent visitors. Similarly, based on stated willingness to pay for the park entry fee, the existing fee is far below than their WTP. This evidence indicates that Tikapur Banglow Park (TBP) bestows huge benefits to the whole society. There should be comprehensive reform project to avail timely adequate park service so as to raise utility from the park.

Assessment of airborne metal pollution in urban parks and industrial areas using Callistemon citrinus and Acacia melanoxylon

Trees have been considered an effective means of assessing metal pollution in urban areas. In the present work, Callistemon citrininus and Acacia melanoxylon leaves were used to assess the air quality in urban parks surrounded by high vehicular traffic and in areas of industrial activity. The concentration of metals (Ca, K, Mg, Fe, Al, Mn, Ba, B, Zn, Cu and Pb) in the leaves was determined, and the results were compared between tree species and site types (parks and industrial). Ca, K, and Mg were found in higher concentrations than the other metals. Although significant differences in the concentration of metals between both tree species only reflected the composition of the plant itself, Acacia melanoxylon seems to display better performance as a biomonitor. According to the contamination factor (CF) results, most of the sites were classified as having suspected, slight or moderate contamination. Moreover, CF and principal component analysis indicated that Cu, Zn, Fe and Al were found to be the most contaminating metals at industrial sites, while Cu, Pb, Ba and Mn were the most contaminating metals at park sites.

Understanding the Linkages and Importance of Urban Greenspaces for Achieving Sustainable Development Goals 2030

Urban greenspaces have an immense contribution to the social, environmental, and economic spectrums of sustainable development. These three spectrums are also the foundation of Sustainable Development Goals (SDGs) 2030. Thus, this interdependence nature offers an opportunity to study the linkages between urban greenspaces and SDGs targets for acknowledging the importance of urban greenspaces for achieving SDGs 2030. To understand the linkages, the study follows a qualitative study approach. In the approach, a convenient systematic literature search technique has been employed to define urban greenspaces and identify empirical evidence on greenspaces’ contribution to different SDG targets. For ensuring the authenticity and validity of the findings, the study includes only peer-reviewed articles in the systematic technique. Results suggest an immediate association between urban greenspaces and SDG target 11.7, which emphasizes explicitly the provision (quality, quantity, and accessibility) of urban parks and playgrounds for the physical and mental wellbeing of urban citizens, typically the social spectrum of sustainable development. In addition to the apparent link, fourteen more underlying connections have been identified where urban greenspaces can contribute to fourteen different SDG targets. These underlying connections acknowledge the importance of urban greenspaces for achieving SDGs 2030.

Using Analytic Hierarchy Process and Best–Worst Method in Group Evaluation of Urban Park Quality

The paper compares two multi-criteria methods, the analytic hierarchy process (AHP) and the best–worst method (BWM), in assessing criteria related to the quality of urban parks. The criteria assessed were accessibility, location, biodiversity preservation, park equipment, water elements, terrain configuration, cultural and historical value, and the presence of small architectural objects. Five decision-makers participated in the research, having expertise in urban greenery, urban forestry, environmental protection, landscape design, and cultural and historical heritage. The results of decision-makers’ evaluations were compared at individual and group levels after the application of three aggregation procedures: CRITIC, ENTROPY, and WGGM (weighted geometric mean method). Similarities in results, i.e., priorities of analyzed criteria after applying the two different decision support methods, indicated high consistency between experts during the cognitive evaluation processes. All applied aggregation schemes performed well and may be considered trustworthy in identifying the group solution. One of the conclusions is that either the AHP or the BWM can be efficiently used in evaluations of criteria for assessing the quality of urban parks if the members of a group are consistent, regardless of whether the consensus process is properly carried out before the decision-making process.

Urban Parks as Perceived by City Residents with Mobility Difficulties: A Qualitative Study with In-Depth Interviews.

Urban green spaces make an invaluable contribution to the health and well-being of all city residents. Therefore, urban park quality and accessibility are crucial factors in stimulating physical and mental health benefits. This study aimed to assess the quality of urban parks and their accessibility as reported by people with mobility difficulties (seniors, blind and partially sighted people). Four key features of a place (accessibility and linkages, comfort and image, uses and activities and sociability) were considered in an in-depth-interviews (IDI) and “walk-and-talk” interviews. Study results indicate a problem of accessibility of urban parks for people with mobility difficulties (uneven gravel surfaces). However, non-physical aspects of park visits (social activities, cultural events, place branding) were reported as essential factors in explaining the motivation for park visits. Despite individual preferences, experience or reported difficulties, all respondents’ attitudes towards park trips were positive. Therefore, we assume that accessibility is more than just physical comfort. Cultural and social activities play an important role in motivating people with a disability to visit a park.

Quality of life and its association with individual and park characteristics among elderly qi gong practitioners in Malaysia

As life expectancy increases, the Quality of life (QOL) among the elderly becomes an essential topic. This study aimed to determine the QOL and its associating individual and environmental factors among elderly qi gong practitioners in Malaysia. This study utilized a cross-sectional design and a self-administered questionnaire, Google Forms, to measure QOL and its associating factors among elderly respondents from a qi gong association. The EQ-5D questionnaire, IPAQ-M and questions adapted from previously published journal articles were used to collect data from respondents. Data were analyzed using SPSS version 22.0, employing multiple linear regression analysis to determine the significance of the independent variables measured against the QOL among this elderly group. The overall QOL for this group was 0.86±0.10, and this elderly group had a higher QOL when compared to other elderly populations. The multiple linear regression model showed that QOL was positively influenced by moderate physical activity level, with standardised b= 0.33, 95% CI 0.04,0.09, p<0.001 and overall park quality score, with standardised b=0.18, 95% CI 0.001,0.005, p=0.001. On the contrary, QOL was negatively influenced by comorbidity with the standardised b=0.26, 95% CI 0.03,0.07, p>0.001. There is a need to promote senior citizen societies to increase awareness of healthier lifestyles. Senior citizen societies can provide quality care, information, and structured activities for the elderly improving QOL.

Slow violence in public parks in the U.S.: can we escape our troubling past?

ABSTRACT Previous studies on environmental justice have paid limited attention to procedural injustice in parks. Using the concept of slow violence, this paper interrogates the ideological and philosophical foundations of American public parks in order to unearth enduring structural patterns of procedural injustice. The paper illustrates that community, state, and national parks in the U.S. were founded upon the elitism, eugenics, and racism of affluent and powerful White conservationists and social reformers. To materialize their own interests, the White elite defined, built, and managed public parks by displacing, excluding, and criminalizing the Indigenous, the poor, people of color, and immigrants. As such, many of today’s park injustices, such as inequitable park availability and quality, gentrification, and non-visitation of people of color, originated from the beginning of the public parks in the 19th century and have been sustained ever since. The paper discusses corrective justice strategies to alleviate the enduring slow violence in parks.

Seasonal and vegetational variations of culturable bacteria concentrations in air from urban forest parks: a case study in Hunan, China.

It is important to investigate the airborne bacterial air quality in urban forest parks as tree bacteriostasis practices are being increasingly advocated as measures to improve the air quality and public health in urban green spaces around the world. The aim of the study was to quantitatively investigate airborne culturable bacteria (ACB) concentration levels based on field measurements in every season in five selected forest communities and the uncovered space in an urban forest park, as well as the effects of several factors on the culturability of airborne bacteria. Results suggested that the airborne bacterial levels of all the forest communities reached the clean air quality standard with regard to the airborne bacteria content, with the highest concentration of ACB showing in the uncovered space (1658 ± 1298 CFU/m3) and the lowest showing in the mixed community (907 ± 567 CFU/m3). The temporal distribution analysis showed that the airborne bacteria were mostly concentrated in summer, as well as in the morning and afternoon. The bacteriostatic rates of the mixed community were significantly different with seasonal variation (p < 0.05). Spearman's correlations revealed that the concentration of ACB was significantly positively correlated with the season, wind speed (WS), temperature (T), ultraviolet light (UV), negative air ion (NAI), and total suspended particles (TSP) (p<0.05) but significantly negatively correlated with the forest community type (p < 0.05). Overall, the selection of tree species plays a key role in shaping the forest structure and improving air quality, and the urban forest highlights key priorities for future efforts toward a cleaner, healthier, and more diverse regional forest environment.

Water quality evaluation of typical Lake Wetland Parks around Dianchi Lake

Dianchi Lake is one of the key management points of China’s “three rivers and three lakes basins”, and the construction of wetland park plays an important role in purifying Dianchi lake water body and maintaining the health of lake ecosystem. Based on single factor evaluation method and three improved Nemerow pollution index methods, this study evaluates water quality of South Dianchi Wetland Park, Xihua Wetland Park and Laoyu River Wetland Park, with concentrations of total nitrogen (TN), total phosphorous (TP), chemical oxygen demand (COD), zinc (Zn), nickel (Ni), cadmium (Cd), chromium (Cr), lead (Pb) specifically measured and monitored. The results showed that: (1) the pollution levels of COD, TN, TP and Cr in the three wetland parks are relatively high. (2) based on single factor evaluation method and the improved Nemerow pollution index method, the evaluation grade of the water quality of the three wetland parks is inferior to Grade V. On the whole, the water pollution of Laoyu River Wetland Park is the most worrisome, and the water pollution of South Dianchi and Xihua Wetland Park is slightly better. (3) COD and TP are the main types of pollutants entering the lake in the basins where the three wetland parks are located. Therefore, immediate attention should be paid to the management of water quality state of Dianchi Lake, and the treatment of urban, agricultural non-point source and some uncollected point source pollution should be further strengthened.

In Beijing, the protected area are the core of the capital's ecological barrier. There are still many problems in the management of the protected area management, and human disturbance(population, economy and transportation) is prevalent, which seriously affects the ecological benefits of the protected area, especially in big cities such as Beijing. The natural factors also have impacts on ecological benefits of the protected area. However, there is still a gap in the understanding of the main factors the affecting the ecological benefits of the protected area in Beijing. We calculated 5 typical ecological benefits of 79 natural protected areas in Beijing, and compared the difference of ecological benefits of 5 types of protected area (natural reserve, forest park, scenic and historical interest area, geopark and wetland park) with one-way ANOVA. The effects of two natural factors (annual average temperature and annual precipitation) and four human impacts (population density, proportion of construction land, proportion of cultivated land and road density) on ecological benefits were investigated based on redundancy analysis. The results showed as follows:(1) in 2020, the value of water conservation per unit area in Beijing's protected areas was 34347 yuan/ha, the value of wind prevention and sand fixation was 2774 yuan/ha, the ecological value of soil and water conservation was 1274 yuan/ha, and the carbon fixation value was only 473 yuan/ha. In addition, the mean value of habitat quality per unit area in Beijing's protected areas was 0.88. (2) While comparing ecological benefits among different types of protected area, except habitat quality, the total benefits of the other four types of ecological benefits, nature reserve and forest parks were significantly higher than the other three types of natural protected areas. The habitat quality of wetland parks was significantly lower than that of the other four types of protected area, and there was no significant difference among the four types of protected area. In terms of ecological benefits of water conservation, scenic and historical interest area and geoparks were significantly lower than other three types of natural protection area. (3) Compared with natural factors (16.63%), human factors (38.92%) were the main factors affecting the ecological benefits of the protected area in Beijing, mainly including wind prevention and sand fixation, soil and water conservation and carbon fixation. Habitat quality was affected by both natural and human impacts, and water conservation was mainly affected by natural factors. ('4) Based on redundancy analysis (RDA), all the protected area in Beijing could be divided into three types:water conservation type, high-quality habitat type, and other ecological benefits (including wind prevention and sand fixation, water and soil conservation and carbon sequestration). The results showed that it was important and urgent to integrate and optimize the protected area in Beijing, and the key point was to reduce the construction and agricultural land in the protected area, and move excessive population out of the protected area. This study was of great significane to improve the ecological benefits of the protected area in Beijing, and provides theoretical and technical support for the scientific management of the protected area in Beijing. 参考文献 相似文献 引证文献

Research on the Influencing Factors of Users&amp;#8217; Perception of the Inclusiveness of Urban Parks Based on the Grounded Theory

The improvement of the inclusiveness of urban parks can guarantee the recreational opportunities and experience of different user groups, especially the vulnerable ones, and is also an important way to promote the justice of urban green landscape. The research explores the influencing factors to park users’ perception and evaluation on the inclusiveness of urban parks. Through the three-level data coding and analysis, a model consisting of eight main categories (i.e. site conditions, site usage, independent mobility, supply-demand matching capacity of space and facilities, interference and limitation of recreational activities, positive emotional experience, broad social participation, and place identity) which cover 30 influencing factors to individuals’ perception of the inclusiveness of urban parks is established. The model shows that park users evaluate the inclusiveness of urban parks upon their observation of site conditions and usage, and their own recreational experience; while the latter is affected by both physical and psychological factors related to passive exclusion and active exclusion, according to the concept of design exclusion. The disparity of the physical environmental quality of urban parks would lead to users’ different emotions and feelings about recreational activities. The model helps clarify the path and key factors of inclusiveness evaluation and provides a theoretical reference for future research and practice of landscape justice.

Water pollution assessment and health risk analysis of Puzhehei Lake

Puzhehei Lake is located in Wenshan Prefecture, Yunnan Province. Water pollution assessment is of great significance for the pollution control of the lake and the sustainable development of the basin. This study evaluates the water pollution and eutrophication status of three sampling points (upstream, middle and downstream) of Puzhehei Lake based on single factor evaluation method, comprehensive pollution index method and improved comprehensive pollution index method based on entropy weight method, and analyzes the water health risk. The results show that the water quality of the three sampling points is sub-class V using the single factor evaluation method. The water quality evaluation result based on the traditional comprehensive pollution index method shows that the water quality of the three sampling points belongs to heavy pollution. By contrast, the improved comprehensive pollution index method based on entropy weight method shows that the water quality of Leshui Cave belongs to class V, while the water quality of Puzhehei Village and Karst Wetland Park belongs to class V. According to the comprehensive evaluation method, the water quality of the three sampling points before and after correction is ranked from good to bad as follows: Leshui Cave, Karst Wetland Park and Puzhehei Village. The water bodies of Leshui Cave and Puzhehei Village are moderately nutritious, and the water bodies of Karst Wetland Park are oligotrophic. The chemical carcinogens health risk in water at the three sampling points exceeded the standard seriously, and the risk ranking was as follows: Karst Wetland Park &gt; Leshui Cave &gt; Puzhehei Village, in which Cr exceeded the standard seriously. The non carcinogenic health risk are low, and the risk ranking is Puzhehei Village &gt; Leshui Cave &gt; Karst Wetland Park. In the future water quality control, we should focus on the strict control of TN and TP in rivers entering the lake.
