Country Park Landscape Quality Evaluation and Optimization Strategies Based on the AHP-TOPSIS-POE Model: A Case Study of Four Country Parks in Shanghai

To clarify the differences in the landscape environment quality of urban country parks, we used the analytic hierarchy process method (AHP) and the approaching ideal solution method (TOPSIS) to build a criterion layer from four points of view: ecological environment, visual landscape, service facilities and humanistic landscape. We selected 21 evaluation factors to form an index layer to evaluate the landscape quality of four country parks in Shanghai. The AHPTOPSIS evaluation system was validated using the post occupancy evaluation method (POE) to verify the accuracy and appropriateness of the system. We proposed landscape improvement strategies based on the evaluation results. The results showed that the combined AHP-TOPSIS-POE model can be used to effectively assign weights to evaluation indexes when evaluating the landscape quality of country parks and to avoid the one-sidedness of single-factor decision making and the errors caused by human subjective factors. The AHP-TOPSIS-POE model provides a new framework for evaluating the landscape quality of urban country parks.

How Thermal Perceptual Schema Mediates Landscape Quality Evaluation and Activity Willingness.

The use of outdoor space is closely related to local microclimate conditions. Some studies have shown that people form perceptual schemata based on their perceptual experience of microclimate conditions, which leads to perceptual bias, so it is necessary to further investigate how the thermal schemata formed by the accumulation of thermal experience affect the willingness to engage in activities, which will be beneficial to improve the use of urban space. Studies have not explored the relationship between the thermal perceptual schema (TPS), landscape quality evaluation (LQE), and activity willingness. Therefore, it is necessary to further investigate how thermal schemas formed by the accumulation of thermal experience affect activity willingness. A total of 3435 volunteers were surveyed online and divided into two groups, the first group for comfortable weather (N = 1773) and the second group for hot weather (N = 1662), and voted for each of the four dimensions of the five scenarios according to the TPS. This study found that socioeconomic status (SES) and age were the main factors contributing to TPS bias when perceiving the same destination according to TPS, and this difference was consistent in both groups, which affects the willingness to be active at the destination. The study also found that LQE may be a major factor in residents’ willingness to be active in more pleasant weather, while TPS plays a more important role in hot weather conditions. In addition, we investigated the relationship between TPS and residents’ activity willingness mediated by different landscape features and parameter configurations. These results indicate that the TPS formed by thermal experience accumulation affects people’s LQE and activity willingness, and that landscape configuration parameters play an important role.

Evaluation of Landscape Quality in Valencia’s Agricultural Gardens—A Method Adapted to Multifunctional, Territorialized Agrifood Systems (MTAS)

Multifunctional agrifood systems with noteworthy roots in a territory are the result of a historical yet dynamic specialization. They are present in the place’s knowledge, social connections, collective action, the organization of institutions, innovation and capital. These systems are seen in the landscape, which becomes a resource as well as cultural and environmental heritage. In this regard, it is necessary to study the significance of the many aspects of heritage and landscape in agrifood systems to suitably manage and appreciate them as a territorial resource. This study develops and applies a quantitative method with various criteria to enable the landscape values of multifunctional, territorialized agrifood systems (MTAS in Spanish) to be evaluated, paying attention to essential matters such as the process of heritage recognition and the quality of their landscapes. To do so, a method designed by the authors for evaluating landscapes has been adapted to the peculiarities that define such systems, made up of criteria such as representativeness, authenticity, ecological integrity, vulnerability, accessibility and historical, social and symbolic values. The method has been applied to an exemplary Mediterranean landscape, the agricultural gardens of Valencia, which combine features of MTAS in metropolitan and coastal flatland contexts.

The Function of Color and Structure Based on EEG Features in Landscape Recognition.

Both color and structure make important contributions to human visual perception, as well as the evaluation of landscape quality and landscape aesthetics. The EEG equipment liveamp32 was used to record the EEG signals of humans when viewing landscape images, structure images with filtered color, and color images with a filtered structure. The results show that the SVM classifier was the most suitable classifier for landscape classification based on EEG features. The classification accuracy of the landscape picture recognition was up to 98.3% when using beta waves, while the accuracy of the color recognition was 97.5%, and that of the structure recognition was 93.9% when using gamma waves. Secondly, color and structure played a major role in determining the alpha and gamma wave responses, respectively, for all the landscape types, including forest, desert, and water. Furthermore, structure only played a decisive role in forest, while color played a major role in desert and water when using beta waves. Lastly, statistically significant differences between landscape groups and scenario groups with regard to alpha, beta, and gamma rhythms in brain waves were confirmed. The reasonable usage and layout of structure and color will have a very important guiding value for landscape aesthetics in future landscape design and landscape planning.

Pristupi vrednovanja krajobraza: propitivanje ranjivosti i osjetljivosti krajobraza otoka Raba

The incentive for this research has come from a wide range of methods for landscape quality evaluation. The purpose was to determine the advantages and disadvantages of the commonly used approaches to landscape evaluation. In the selected research area, the Island of Rab, 15 landscape character areas were identified and three approaches for evaluation of landscape qualities were determined; (1) one based exclusively on the evaluation of vulnerability of landscape qualities, and two based on landscape sensitivity assessment: (2) the overlap of landscape character areas with the combined landscape quality vulnerability model and (3) the direct evaluation of landscape character areas from the natural, cultural-historical, and visual-experiential perspective. The aforementioned approaches were compared with one another in order to identify similarities and differences between the individual approaches, as well as to highlight their advantages and disadvantages. Theresults have shown that the adequacy of an approach depends on the selection of a homogeneous spatial unit; the appropriate approach for the evaluation criteria selection may affect the objectivity of the method; and the highest landscape qualities were determined in the same areas regardless of the approach used.

Research on landscape quality of country parks in Beijing as based on visual and audible senses

Construction of Chinese country parks has been developing quickly in recent years, but less effort has been made in the field of esthetic quantitative evaluation of landscape of the country parks. Based on the theories of landscape esthetics and psychology, this paper constructs a landscape quality evaluation model for the country parks by means of SBE and SD methods, with which the authors of the paper carried out the research on and evaluation of the landscape quality of four selected country parks outside the Fifth Ring Road in Beijing. The purpose of this paper is to further put forward suggestions for a better development of the landscape of the four country parks in order to bring their landscape and recreation functions into full play. The findings of this paper indicate that both natural and artificial landscape characteristics exercise either positive or negative influences on landscape quality; among them the effect of vitality, color richness, senses of both joy and beauty are the key elements affecting the attraction of the country park's landscape. Country parks boast with special significance because of their localism, naturalness and tranquility. These advantages are fully shown in their sufficient space for waterscape construction and conspicuous effect on landscape as reflected from the green belts previously constructed. Nevertheless, three major problems existed in the country parks including insipid color, over artificialized parkways, and peripheral high-rise buildings in the nearby neighborhood that have also given rise to visual interference. Recommendations for relevant landscape construction and protection of the country parks are suggested.

With the development of the world, public demands for recreation opportunities and scenic beauty of forest have risen substantially in recent decades. Providing recreation activities is one of most important function of forest. The Scenic Beauty Model was established to predict landscape quality, the results were obtained by using Quantification Theory Type I for multiple regression models. The variables in the model of contribution rate can be seen, shrub coverage has the greatest influence in landscape quality, the following variables were canopy density, average height of first alive branches, noticeability of dead branch et al. Then management measures were put forward. It is important for managers in better understanding the interactions between scenic beauty and other forest attributes, has an important role in construction of scenic and recreational forest.

Thinking soundscapes into the management of country parks

Countryside and Country Parks, commonly used as an area for recreation, conservation and education, accommodates sunlight and allows free air movement, thus providing visual relaxation. In recent years, ways to make country parks more attractive for use have been highlighted worldwide. Among a number of promoted common themes regarding the protection and enhancement of country parks, sound as a component of the biological and social environment should be utilized for improving the general environmental quality. Based on the large scale field recordings and questionnaire surveys carried out in 3 country parks in Hong Kong countryside, the relationship between subjective evaluation of soundscape and landscape quality as well as the particular contribution of sound in the enhancement of country parks have been statistically analyzed. Results of this study demonstrate a close relationship between subjective evaluation of landscape quality and acoustic quality. Identification of different sound sources in different functional zones, their particular properties and influence on subjective evaluation of the acoustic quality suggests an alternative approach for improving the acoustic quality and consequently the general environmental quality at the countryside location.

Public Satisfaction of Highway Landscape Quality: A Case Study from China

The research presented here constructed highway landscape quality evaluation indexes and a model based on public satisfaction. The goal was to determine if public satisfaction of highway landscape quality can be statistically measured. Several methods of highway landscape quality evaluation were first reviewed to determine what limitations were existed. From that review, a highway landscape quality evaluation indexes were selected and a model based on the selected indexes were constructed according to theory of public satisfaction. An on-site study was conducted to obtain public satisfaction of a scenic road using the selected indexes and model, statistical methods were employed to test the validity and reliability. Results indicate that the public satisfaction can reflect the quality of highway landscape, and the selected indexes can fully represent highway landscape quality.

Spatial modelling of potential landscape quality

Quality of landscape directly affects the day to day quality of life of all the people living in it. It is strongly bound to landscape components and features and to their spatial and functional interrelations. Potential quality, in particular, is determined by elements of value that, in relation to their characteristics of integrity and importance, result in an enhancement in landscape quality. More effective analysis and evaluation of quality of landscape elements, and their contribution to landscape quality, are essential for supporting modern landscape analysis and planning. In this regard, multicriteria techniques, and Analytical Hierarchy Processes in particular, can support the definition and development of quantitative methods aimed at the modelling, analysis and evaluation of landscape quality. GIS spatial analysis of quality indicators derived from multicriteria techniques generates map layers of landscape quality based on density and quality level of the landscape elements. Within GIS, progressive multicriteria aggregation of landscape quality layers produces synthetic spatial indicators that can support effective interpretation of the gradients characterising landscape configuration. The methodology has been applied to an internationally recognised historical-cultural area in the territory of Assisi (Umbria, Italy). The specific objective has been validation of the methodology by assessing potential landscape quality in relation to the most important physical-naturalistic, historical-cultural and social-symbolic elements. The results have shown that spatial gradients of landscape quality can be effectively modelled by the combined use of GIS and multicriteria methods.

Evaluating landscape quality with vegetation naturalness maps: an index and some inferences

Question: Can landscape quality be evaluated and compared with a single numerical value using vegetation maps?Location: Northern Apennines (Italy), ca. 44° N,10–11° E.Methods: Seven phytosociological vegetation maps (1:25000), which correspond to man's different impact on mountain landscapes, were considered. Syntaxa were classified into five degrees of naturalness: urbanized, agricultural, semi‐natural, sub‐natural, and natural. Vegetation maps showing naturalness were derived in a vectorial GIS. The degrees of naturalness were ordered according to increasing naturalness. If c1 is the cumulative relative value of every mapped area of the degrees of naturalness, the sum of these cumulative values A =∑ ci is is a measure of vegetation artificiality. Its maximum value is Amax= n‐1. The Index of Vegetation Naturalness IVN = 1 ‐A/Amax, ranging from 0 to 1. Our IVN is an extension of the ILC by Pizzolotto & Brandmayr (1996) due to the ordinal character of the vegetation classification into degrees of naturalness. The maps of vegetation naturalness were also analysed by two known metrics for the evaluation of landscape quality: TECI (Total Edge Contrast Index) and MSI (Mean Shape Index).Results: The case studies show that IVN is linearly correlated with decreasing area of urbanized and agricultural vegetation types as well as with increasing area of the highest degree of naturalness.Conclusions: IVN can be joined with the TECI for the evaluation of naturalness of landscapes. TECI can supply additional information about the importance of landscape ecotones. Our case studies suggest that an urbanized landscape should correspond to IVN values lower than 0.20. A natural landscape will have IVN values higher than 0.80.

Restoration of a river landscape: Biotopes as a basis for quantification of species diversity and evaluation of landscape quality

This study was conducted in three river stretches, which are comparable in their natural features and conditions, but whose principal difference is in floodplain land use. Thus, they are different in the extent to which anthropogenic disturbance influences the river. The sum of the biotopes in each stretch was measured and groups of functional biotope types made. Biotopes diversity indices, as well as species diversity in aquatic and terrestrial ecosystems measured by the Shannon-Wiener function and by the Simpson's index, were calculated. Microbiotopes were defined and species diversity was measured within them.
