Characteristics Of Natural Environment Research Articles

Türkiye’deki Hayvancılık Alanının Mekansal Kalıplarını Coğrafi Varyanslarla Bağlama

The livestock sector is considered as an essential economic source in the economic policies of many developing countries in the world. The present research aims to analyse the spatial association and dependence of livestock in Turkey by using the exploratory spatial data analysis (ESDA) technique. Livestock data of 966 cities from 2004 to 2017 have been used to detect spatial distribution, clusters and hotspot areas of cattle and small ruminants’ populations. It has been revealed that livestock production is strongly associated with the natural environmental characteristics of spatial units throughout the country. Spatial autocorrelation has shown the positive values for both cattle and small ruminants, but stronger for the latter. Besides, a change in the clusters of cattle populations has also been observed over the selected period. Apart from the natural environmental factors, several socio-economic issues like rural outmigration, government policies, industrial requirements and regional disparities have also been found responsible for the change in the spatial patterns of livestock. The research provides significant outcomes for better allocation of resources in priority areas to develop the livestock sector. Moreover, it also facilitates pointing out the potential areas of livestock development in the future.

Trophic degradation predispositions and intensity in a high-flow, silted reservoir.

The objective of the work was to demonstrate the relationship between the natural environmental characteristics of a reservoir and its catchment and severity of trophic degradation. The shallow, highly-silted Rzeszów Reservoir (SE Poland) was the object of study. The impact on degradation of internal supply from accumulated bottom sediments was also assessed, using water and sediment sampled in 2013 and 2014. A high value for trophic state was identified for the reservoir on the basis of TSI indexes, while assessed natural resilience to degradation and analysis of the catchment as a supplier of biogenic and organic matter both indicate high susceptibility to cultural eutrophication. Obtained values for equilibrium phosphate concentrations under anoxic conditions (EPC-0) point to the possibility of a more intensive process of internal supply in phosphorus. However, the presence of sediments poor in organic matter suggest no major threat of ongoing eutrophication. Desludging and/or dredging are likely to entail elimination from the ecosystem of a large part of the pollutants accumulated in sediments, as well as the internal supply of phosphate to the water column. However, as external sources are responsible for the advanced degradation of Rzeszów Reservoir, any attempts at reclamation within the water will fail to yield persistent effects if appropriate protective procedures in the catchment are not implemented.

Late-Holocene vegetation change reveals the environment of ancient people and the origin of Huashan cliff paintings in Guangxi, southwestern China

Human activities in the historical period were determined by the natural environment and social characteristics. The Zuojiang Huashan Rock Art Cultural Landscape in Guangxi is the most important World Heritage for prehistorical culture in southwestern China. However, knowledge about the natural environment and associated historic human–climate interactions during the period of cliff painting creation remains scarce, which has been an obstacle to understanding the process of regional civilization. Here, we report a pollen record from the core distributing region of Huashan cliff paintings to interpret the natural environment and climate changes, and further to discuss how and why ancient people create these giant cliff paintings based on the relationships of human–climate interactions. Pollen results imply an existence of a mixed broad-leaf and conifer forest in the woodland landscape at Huashan region before 1860 cal. yr BP, after which pine forests were more prevalent. During the cliff painting period from 2370 to 2115 cal. yr BP, broad-leaf and conifer trees dominated the tree layer and provided the key source materials for painting. It can be reasonably assumed that people used stake or ladder to climb the cliffs and created the cliff paintings during a humid climate condition from 2560 to 2000 cal. yr BP. Furthermore, the humid climate during 2700 and 2400 cal. yr BP had been interrupted by short-term drought episodes. These turbulent climate episodes probably played the role of disasters and impacted on the human activities, leading to the social–political tensions and the out-break of war. During the Qin and Han Dynasties, social–political changes relieved the pressure from natural climate changes and led to a more stable society, in which the creating of cliff paintings was gradually fading. Our results manifest the necessity to analyze the natural environment and social–political background in combination in this study on ancient human activities.

How to organise limited space: Micro-regionalisation of La Digue island (Seychelles)

Abstract Islands, especially small ones, are commonly studied as microcosms of natural and social processes. In this article, La Digue island (10 km2) in the Seychelles archipelago was treated as such. An attempt was made to analyse the significance of the natural environment for the features of spatial development under conditions of intense globalisation. For this purpose, functional micro-regions were determined, along with their genesis and evolution. Spatial dynamics and individual features of space are presented as chorème (Brunet 1986). The analysis was based on data from a library query and field observation and field studies in July 2018. Twelve functional regions were determined. Analysis of the distribution and evolution of their functions reveals a high dependence on natural environmental features, especially topography, and thus confirms (at the scale in question) a geographical determinism.

The Effects of Tourist Site Attractiveness on the Selecting Tourist Destinations, Tourism Visits and the Travel Expenditure: Case Study on Gangwon Province

The purpose of this study is to analyze the effect of tourist site attractiveness on the selecting tourist destinations, tourism visits and the travel expenditure. The tourist attractiveness is classified into natural environment characteristics and artificial characteristics. Natural environment characteristics imply that whether the region has beaches and national park and artificial characteristics imply that whether the region has regional festivals and resort-related infrastructure. By using a conditional logit model, we analyze the effect of tourist site attractiveness on tourists choice of tourist destinations. The effect of tourist site attractiveness on tourism visits and the travel expenditure is estimated by generalized least squares. According to the estimation result, tourists are more likely to select regions with beaches or national parks and regions with many festivals and resort-related infrastructure. Tourism visits is high in regions with beaches and many festivals. It is estimated that travel expenditure is high in regions with beaches or in national parks.

Multiobjective UAV Path Planning for Emergency Information Collection and Transmission

Considering the problem of rapid collection and reliable transmission of emergency information, as well as the emergency response missions and natural environment characteristics of emergency sites, this article proposes a novel unmanned aerial vehicle (UAV) path planning framework that considers waypoint and motion. First, the waypoint planning improves the reliability of the uplink and the downlink data transmission to the greatest extent by jointly optimizing UAVs 3-D position and transmit power of UAV and users’ equipment (UE). Second, the motion planning allows the UAVs to traverse all waypoints in the shortest amount of time, which allows more time for data collection by maximizing the acceleration of each UAV. Our results show that the proposed path planning algorithm can significantly improve the normalized Quality-of-Experience (QoE) index and effectively shorten the flight time of each UAV for different assignments. Therefore, the method proposed in this article can effectively solve the key problems in the technical system of emergency response and provide a scientific decision-making basis for the post-disaster emergency response.

Selecting a site for the nuclear power plant underground installation during new fields development

Introduction. The construction of underground installations in permafrost is aimed at ensuring the integrated safety of power facilities, small nuclear power plants (SNPP). In these conditions, location choice is a crucial stage in SNPP design and construction. As a rule, construction sites are situated at remote and little developed territories. Construction in permafrost is characterized by adverse climatic conditions and frozen soil, which lead to construction cost indicators growth. Research aim is to carry out comparative evaluation of two sites available for the facilities arrangement at the Peschanka copper porphyry deposit by ranking SNPP location sites. Methodology. Natural and climatic conditions play a significant role in siting and are capable of affecting the safety of both the nuclear facility and surrounding territories during a nuclear power plant operation. The choice of the station location is associated with a number of natural and man-made environmental characteristics. Results. The determining factor in the use of the energy sources under consideration is the need to bring them closer to the main energy consumers, especially in remote and hard-to-reach areas without developed infrastructure. As part of SNPP creation concept, there is an increasing significance of research concerning the siting of underground radiation-hazardous facilities. The methodical approach to selecting sites for underground installations in permafrost includes their ranking. Summary. While ranking the sites according to natural and socio-economic criteria, the most acceptable sites for SNPPs are identified. The results of research on the choice of particular sites during the construction of a mining and processing complex at Peschanka deposit have made it possible to make a conclusion on the site’s suitability for underground installation adit location.

For a long time, the Baiyangdian Wetland has gradually shrunk and even dried up under the combined effects of human activities and climate change. It is of great significance to study the carrying capacity of ecological and environmental in the Xiong'an New Area by understanding the ecological function and regionalization of the Baiyangdian Wetland ecosystem. This is one of the current widespread concerns and urgent problems to be solved. In order to meet the needs of ecological protection and management of Baiyangdian Wetland, this study evaluated and regionalized the ecological functions by combining methods of field survey, remote sensing, and comprehensive evaluation. Images of Landsat MSS/TM/ETM+/OLI in 1975-2018 and GF-2 PMS in 2017 and 2018 were acquired to analyze land use/land cover change. Firstly, on the basis of clarifying characteristics of natural environment and main ecological problems of Baiyangdian wetland, the indicators system was constructed for evaluating ecosystem service function and ecological sensitivity. Secondly, the ecosystem service functions were evaluated from five aspects:supplying of aquatic products, supplying of aquatic plants, climate regulation, biodiversity maintenance, and improvement of water quality. The ecosystem sensitivities were evaluated from three aspects:water pollution, wetland changes as well as importance of natural and cultural values. Finally, based on results of evaluation, the Baiyangdian Wetland was initially regionalized into seven first-level ecoregions and nineteen second-level ecoregions. We combined ecological processes and impacts of human activities into ecological regionalization, reflecting the dynamic characteristics of human-land relationships in Baiyangdian Wetland. The results covered spatial and temporal characteristics of the ecological environment, which could help manager to make decisions for the ecological protection planning in the future. We suggested that regionalization-oriented measures should be formulated according to the ecoregions characteristics in the process of implementing project of ecological environment protection and management in Baiyangdian Wetland. 参考文献 相似文献 引证文献

ANALYTICAL STUDY OF HERITAGE RESIDENTIAL BUILDINGS IN THE CENTRAL REGION OF SAUDI ARABIA

The architecture of any nation reflects the social and religious concepts of the citizens’ lifestyles, as well as the extent to which people in one nation are connected and influenced by other civilisations. The architectural style of the Kingdom of Saudi Arabia (KSA) is not much different from that of the Arabian Peninsula. Saudi architecture has been designed with a consideration for natural factors, such as climate and the environment, and has also been influenced by the human environment, including social and economic factors. The general structure of the urban fabric appears random, in terms of form and layout, but this, in fact, corresponds to certain necessities forced by the local environment. This study aimed to identify the social and natural environmental characteristics of residential heritage buildings in the central region (Najd area) of the KSA. The factors that have affected these unique residential designs, which are based on adaptations to the natural environment, are highlighted. Based on the study, recommendations are made that can be applied in future architectural projects in the region.

ĐỀ XUẤT CÁC GIẢI PHÁP GIẢM THIỂU TÁC ĐỘNG DO ĐỔ THẢI BÙN CÁT NẠO VÉT Ở VÙNG VEN BIỂN HẢI PHÒNG

Located in the estuary region of the Red - Thai Binh river system, in which the estuarine turbidity maxima occur, the deposition of navigation in waterways to Hai Phong ports is always an urgent problem that needs to be solved. At the present time, it is not easy to use dredged sediment for landfilling or other purposes. Moreover, it is also difficult to dispose of them on the land because of requiring the design and construction of dikes, requiring compaction and drainage of dumped materials. Therefore, disposing of materials at dumping sites in Hai Phong open waters is still an alternative for considering. However, the suspended sediment from the dumping sites can cause influences on the marine environment and ecosystems. Based on the characteristics of natural conditions, socio-economy and ecological environment in Hai Phong coastal areas as well as results of the modeling application (Delft3D model), this paper gives some proposals for appropriate solutions to reduce influences of sediment dumping activities in the Hai Phong open waters. They are: (1) Planning a land for reclamation of dumped materials, (2) Research on the strategies to use dredged sediments as a resource, (3) Finding a best method of dumping, (4) Considering tidal current for daily dumping, (5) Choosing disposal time during neap tide, (6) Restricting disposal in case winds come from SW and S, (7) Reducing time and the number of dumping, increasing amount of sediments in each dumping, (8) Applying technologies in disposal monitoring, (9) Regularly monitoring the environment at the dumping sites and adjacent areas.

The effect of urban green space on uncertainty stress and life stress: A nationwide study of university students in China.

The aim of this study is to investigate the impacts of urban green space on stress among Chinese university students. Participants were 11,954 students from 50 universities in 42 cities. Each student completed the Global Health Professional Student Survey (GHPSS) on Tobacco Control in China. Regional variables were retrieved from the National Bureau of Statistics database. Both unadjusted and adjusted methods were used in the logistic regression analysis. Almost one third of the students (31.1%) suffered from high levels of uncertainty and life stress. The multilevel logistic regression model showed that while certain individual and environmental factors, such as higher family income, having parents with a professional occupation and urban home location, reduced uncertainty stress among students, so did the effects of green space. This was particularly important for reducing uncertainty stress but also had some effects on life stress. The findings support a wider body of literature on the positive effects of green space on stress and mental health. Future studies need to pay greater attention not only to intra-urban differences in student use of green space, but also to how the natural environment features in stress management policies in Chinese universities.

Microscopic Analysis and Study of High-Performance Seawater All-Coral Concrete

The ocean islands are far from inland and the concrete sandstone aggregates are scarce. In this paper, high-performance seawater all-coral concrete was developed by seawater mixing and room temperature maintenance design, and by optimizing the water-to-binder ratio, regulating internal curing, changing auxiliary cementing materials and blending ratio, incorporating expansion agent, adjusting fiber blending, etc. Combined with the consideration of work performance and mechanical properties, the concrete self-shrinkage is adjusted to further optimize the mix design. The mechanical properties of the optimized high-performance seawater all-coral concrete were studied, and the relevant durability tests were carried out according to the natural environment characteristics of the island. This is of great significance to the construction of island projects, repair and construction, and construction of protective projects [1].

ORTAKLAR KÖY ENSTİTÜSÜNDE MODERN MİMARLIĞIN İZLERİ

Village institutes are public institutions that have an original education system established to equalize the balance between rural and city in the modernization process of the Republic of Turkey. The Ortaklar Village Institute that 30 km from the Aydin is the one of a total of 21 institutes have been opened in different regions of Turkey. The foundation of the institute was laid in 1944. Due to the fact that it is the only institute in the vicinity, it has been expanded with new classrooms and buildings added over time and has become a campus with about 30 buildings..There are traces of period ideology in the layout and architectural characteristics of the buildings that serve different functions. In the site plan a layout consisting of buildings on both sides of the rational axis is dominant. In the designs based on geometric forms, the use of semicircle form and long horizontal strip windows reflect the architectural language of the modernist movement. The institite that reflecting the Republican period adds value to archtitecture with its natural environment, settlement style and architectural features. In this study, the structures belonging to the Ortaklar Village Institute, which was built in accordance with the modernist philosophy, will be examined in terms of architecture.

Arctic cities as an anthropogenic object: a preliminary approach through urban heat islands

ABSTRACT Although there is a growing body of research on Arctic urbanisation and the development of cities in harsh polar climate, few studies focus on the long-term interaction of urban environments with the natural world and society. As the search for determinative links between natural environmental characteristics and socio-cultural phenomena is exceedingly complex and obscured by human decision-making, it is more fruitful to adopt another perspective – one that views the city as an anthropogenic object combining natural, social, and cultural features and phenomena. The HIARC (Anthropogenic Heat Islands in the Arctic – Windows to the Future of the Regional Climates, Ecosystems and Society) project helps to fill this knowledge gap by bringing together traditional climate science that operates on large spatial and time scales; micro-level high-resolution studies that provide relevant practical details about the changing environment; bio-medical science that studies the physical adaptation of newcomers to the Arctic environment; and an array of social science approaches that range from political science on urban regimes to sociology and cultural anthropology that capture evolving human environments. This article offers a preliminary agenda for thinking about cities as an anthropogenic object in a polar context.

Understanding Nature and Its Cognitive Benefits

Many people have the intuition that interacting with natural environments benefits their psychological health. But what has research actually demonstrated about the benefits of nature experience and the potential mechanisms underlying those benefits? This article describes empirical research on the cognitive benefits of interacting with natural environments and several theories that have been proposed to explain these effects. We also propose future directions that may be useful in exploring the extent of nature’s effects on cognitive performance and some potential mediating factors. Specifically, exposure to a variety of natural stimuli (vs. urban stimuli) consistently improves working memory performance. One potential mechanism for this is the perception of low-level features of natural environments, such as edge density in the visual domain. Although low-level features have been shown to carry semantic information and influence behavior, additional studies are needed to indicate whether perceiving these features in isolation is necessary or sufficient for obtaining the cognitive benefits of interacting with nature.

The Climate changes and its impact on tourism activity Applied to Sharm El Sheikh

The tourism sector is the most sensitive among the economic sectors to the potential impacts of climate change, since that the Tourism sector is closely connected to the natural environmental resources and cultural characteristics of the region, which are also highly sensitive to fluctuations and climate change. Sharm El Sheikh is characterized by its geographic location, climate, natural resources, wildlife, and marine life which are suitable for all tourism activities such as beach tourism, diving tourism, water sports, safari tourism, and other activities. The research aims to study the climatic characteristics of Sharm El-Sheikh and analyze their impact on tourism activities in the region, and forecasting the impact of climatic elements in Sharm El-Sheikh during the next climatic cycle on tourism activities. The study has used the time-series method (the Box-Genghis method) to predict the expected climatic data in Sharm El-Sheikh; in addition, to the Oliver Scale to clarify the relationship between climate and tourist comfort. Moreover, Illustrations and maps are also drawn for the future diving spots at the shores of Sharm el-Sheikh
