The Forestry Space Layout Based On "Nanchang-Jiujiang Integration"

The speeding up of urbanization promote the development of economic and social, but also brings a series of ecological environment problems. Forestry is measures to solve the urban population explosion, shortage of resources, energy crisis and environmental pollution. "Integration of Nanchang and Jiujiang" is the inevitable trend of regional development, put the construction of forestry in to a longer time span, wider area, considering of the role and positioning of forestry construction in large area, so as to do a good job in regional sustainable development of city space layout planning of forestry, and is the only way for ecological construction and environmental protection.This paper taking the spatial layout of forestry of ChangJiu as the research object,from the urban agglomeration, urban forestry and the basic theory of urban forestry and so on, analyzes the present situation and problems of ecological environment and forestry of ChangJiu, discussed the forest needs in the international per capita urban forest standard and carbon and oxygen balance standard under the area of ChangJiu, using the method of economic relation intensity analysis and principal component analysis method to calculate ChangJiu’s each district to Nanchang city’s economic strength and urbanization level of ChangJiu county area. On the basis of city land-use and urban planning of Nanchang and Jiujiang, discusses the general and detailed spatial layout of ChangJiu. The results show that:(1)ChangJiu’s ecological environment problems intensified year by year, woodland area increased slightly, but it has significant difference in space, there are many problems exist such as single tree structure, smaller ecological benefits and so on.(2) ChangJiu’s lowest demand of forest is 606.46km2 and 7136.36km2 respectively, and has obvious spatial differences, the layout of forestry should taking the spatial distribution of forest resources into account as a whole, making full use of forest resources of the outskirts in ChangJiu to make up forestry of the core to achieve overall balance.(3) ChangJiu’s overall forestry space is divided into three spheres: forestry lack of core area of urban agglomeration, urban and rural outskirts of forestry area, urban agglomeration of peripheral forestry enrichment region, Make full use of rivers, lakes, nature reserves and the key ecological function areas of the area, increase forest area in the area; Attaches great importance to the regional forestry space layout such as commercial, industrial area, traffic along, ect, forming a scientific and reasonable space layout structure of forestry, promote the sustainable development of forestry, it has important significance to the forestry space layout of ChangJiu and Poyang lace urban agglomeration.
