摘要
From the angle of ecology,urban agg lomeration presents relevant types of landscape structure,which in-clude Patch,Corridor and Matrix.There are different landscape feature s and different problems in differen t development phases.This paper has put forward fi ve basic conditions for security pattern of landscape ecology of urban agglomeration,described quantitatively the featu res for landscape ecology in Wuxi,an d analyzed ecological background of spatial expan-sion and spatial organization of urb an development in Wuxi.From the angle of ecological land use and non-ecological land use,the paper has analyzed the featu res of land use and ecological distribution of land in the urban area.The s patial mod-el of cities and towns in Wuxi is composed of one metropolis,two urban zones and three development axes.This th esis has planned preliminarily ecologic al protection network at four levels in the urban region according to four layers.At last,combining landscape ecology with ur ban space,a tentative security pattern of landscape ecology has been pla nned in Wux-i,namely Source-Buffer Zone and Metropolis,Radiating Routes and Expan sion Direction of City,Strategic Point and Interac-tion between Cities and Towns,Inter-Source Linkage-Corridor of a Stabl e Landscape Structure.
From the angle of ecology, urban agglomeration presents relevant types oflandscape structure, which include Patch, Corridor and Matrix. There are different landscapefeatures and different problems in different development phases. This paper has put forward fivebasic conditions for security pattern of landscape ecology of urban agglomeration, describedquantitatively the features for landscape ecology in Wuxi, and analyzed ecological background ofspatial expansion and spatial organization of urban development in Wuxi. From the angle ofecological land use and non-ecological land use, the paper has analyzed the features of land use andecological distribution of land in the urban area. The spatial model of cities and towns in Wuxi iscomposed of one metropolis, two urban zones and three development axes. This thesis has plannedpreliminarily ecological protection network at four levels in the urban region according to fourlayers. At last, combining landscape ecology with urban space, a tentative security pattern oflandscape ecology has been planned in Wux-i, namely Source-Buffer Zone and Metropolis, RadiatingRoutes and Expansion Direction of City, Strategic Point and Interaction between Cities and Towns,Inter-Source Linkage-Corridor of a Stable Landscape Structure.
