The Study Of Green Space Ecological Network Planning Based On Suitability Analysis In Cangnan Country

The green space ecological network provides an important space safeguard for recreational greenspace and ecological protection of green space. Its rational layout can not only reduce the degree offragmentation of green path, improve green space layout, improve the ecological network connection,but also help to limit the unlimited expansion of the urban, thereby enhancing the ecological value ofurban ecosystem to some extent.The paper technical support to Fragstats and GIS, combined with field research of the study areafor classification interpret of the remote sensing image to get study area landscape type map. First,analyzed the landscape pattern in Cangnan Country. Then selected5ecological suitability evaluationfactors for evaluation, integrated weighted to get an ecological suitability map as a consumersurface,then simulate the potential ecological network in Cangnan Country. And combined withlandscape pattern analysis, analyzed the spatial distribution of ecological corridors and greenpatches.Finally, based on the above analysis, integrated theory of landscape ecology, propose rationallayout recommendations of the overall layout of green space ecological network in Cangnan Country.The research results show that:(1) The different landscape types on both the number anddistribution are imbalances. Counties in the plains of Northern and North-Eastern regions of land forbuilding, transportation, water are most concentrated, causing fragmentation of green plaque in theregion in serious. The green plaque area is larger in the region, but the distribution is uneven, especiallyin the Central and Western regions lack the number of green plaque, the connection degree between theplaque is not enough.(2) Proceeding from overall regional landscape, identified the green space ecological networkplanning layout of “two belts, five horizontal, eight vertical, multi-point”, and to build it.“Twobelts”construction of coastal protection shelterbelts and mountain-type corridor;“Five horizontal, eightvertical” from road corridor and river corridor to build;“multi-point”from seven aspects-parks, attachedgreen space, the other green space, village green, ecological forest, green cover mine, farmlandshelterbelt to built. In order to build urban-rural integration of green space ecological network together. Combining landscape pattern analysis and GIS technology, is based on suitability analysis, tosimulate the potential ecological network in the study area, combining qualitative and quantitativeresearch, provides technical support and scientific basis for the green space ecological network planninglayout.
