Study On The Impact Of Microclimate On Mountainous Urban Design Under The Perspective Of Geo-ecological

Geo-ecological environment is composed of geological environment,ecological environment and human social economic environment.It is the material basis for human survival,and provides the material and energy sources for human society. The cause of formation of the microclimate is the interaction of the underlying surface conditions and solar radiation,the atmospheric circulation Geological environment factors and Ecological environment factors as the main part of the underlying surface,which has an important influence on the formation of the microclimate,and the Geological environment factors is the main factor influencing the climate microclimate.Mountainous town’s geo-ecological environment has its particularity and complexity,which caused the diversity of mountain microclimate, provides rich climate resource.if it is the rational use of climate resources in the mountain citydesign,itwould be important significance to create a good environment of mountain town.However, in the process of the construction of mountain town areas,because of the irrational use of Geological environment resources and the irreversible destruction of the natural geological environment and ecological environment,has caused a lot of ecological environmental problems in mountain towns.Such as heat island effect, poor ventilation, extreme weather and other issues.It seriously hindered the development of the city and human comfort requirements.So under the background of the new national urbanization to speed up the construction of Green city and serious climate problems of mountain towns, exploring the adapt to the climate of mountain city design which starts from the perspective of Geo-ecological,it has important theoretical and practical significance for alleviating the heat island effect, control of air pollution in the city, reducing the energy consumption of the city and sustainable development of mountain city.Study on the impact of microclimate on mountainous urban design is Sub project of the National Natural Science Foundation of China.The framework for the paper is:The first chapteris the introduction,which is the origin of this study.It mainly introduces the background of the paper, research status at home and abroad, the purpose and significance and the definition and research framework.The second chapteris the study of microclimate theory under the perspective of Geo-ecological. Constructed the relationship between Geo-ecological environment and microclimate.Firstly,Carding the connotation of Geo-ecological environment,composition elements and the elements of the thesis;Then Analysised the Geo-ecological environment factors which are the main reasons of microclimate formation;After the Geo-ecological environment factors impact on the microclimate;Finally, summed up the impact of microclimate on city environment.The third chapter is to explore the concept of microclimate of mountainous urban design under the perspective of Geo-ecological.Firstly, analysised the main climate object of mountainous urban design.Then raised the mountainous urban design connotation, target and factors.Finally analyzed the principle of microclimate regulation.The fourth chapter is the research on the mountainous urban design strategycombined with microclimate under the perspective of Geo-ecological,which is a core part of this paper.In the guidance of the theoretical frame, raised the mountainous urban design strategy from four part,which is Mountainous urban space form,open space,road network system,mountainous building’site and layoutThe fifth chapter is the application part,Based on a practical project the author participated in the urban design of Hanyuan County Jiu Xiang town. Combined with the above theory and method,According tothe condition of the Geo-ecological environment and the unique climate characteristics of Jiu Xiang town.Putted forward the design strategy.The sixth chapter is the conclusion.Summarized the contents of this paper,and And putted forward the limitations of this paper.
