Studies On Area Climate Effect Of Greenbelt System And Landscape Ecology Construction Of Urban Of Hefei

The relationship of human race and environment has become the focus of the world. Along with the development of city, pollution and devastation become serious. For the sake of self-behalf, mankind has destroyed the balance of nature. In the face of the crisis, people are searching for a road that can collaborate the relation. Building ecology garden city is our aim in the future, but we must go persistence road.The content of building ecology garden city conclude building and improving greenbelt system of city. With the development of science, special ecology, city climate, city environment, city greenbelt have its theory direction. Of late years, landscape ecology become thrive and milestone of building city greenbelt. Landscape ecology connects ecology and geography etc. and it becomes theory base of modern times city planning. This paper concentrates on the focus of the world and concerns building of greenbelt system of Hefei and studies on the ecology effect of city greenbelt system and compares climate feature of varying soil surface. Studying on drop temperature effect, add humidity effect, balance of carbon and oxygen effect, absorbing dirt effect, killing germ effect, decreasing noise effect and air anion effect. We acquire a lot of weather datum from Anhui province weather station. By means of datum, we study on affection of landscape transition, study on every weather factor and using time series methodology, SPSS statistics software, we can forecast the weather in the future. We can conclude the action of greenbelt system of city. The last of the paper introduce some base theory of landscape ecology in particular,for example: patch—corridor—matrix theory, life diversity principle, landscape conjunction and landscape connectivity principle and narrate some scheming principle, as: ecology, nature priority principle, persistence development and diversity principle, suit measures to local conditions principle, focalization principle, integration principle, synthesis principle etc. And this paper points out method of greenbelt system scheming of city too. It includes rather greenbelt scale and quantity, adding greenbelt landscape diversity and space heterogeneity, rational layout, making green corridor, taking into account integration afforest, perfecting structure and function of greenbelt system, being practical and realistic, making the most of nature conditions, all with people, nature and culture together, establishing my feature city. It tells how to exert landscape ecology principle that directs our constructing of greenbelt system in practice. And I assays present conditions of greenbelt system of Hefei in particular. I evaluate the present conditions of greenbelt system by index of landscape ecology. Meanwhile I find some defect and give some advice about greenbelt system and scheming goal and meth.
