江苏省生态保护与建设空间分布耦合状态评价

Assessment of spatial coupling between construction space and ecological protection areas in Jiangsu Province

根据生态空间保护需求,调整产业与城镇开发方向,是协调建设布局与生态保护空间关系,进行区域空间引导和控制的重要内容.以江苏省为案例区,在划定生态功能保护区、提取现状建设空间分布信息的基础上,运用矩阵分类和空间分析方法研究了生态功能保护区与建设空间的耦合特征及生态功能保护区的建设占用状况,总结了空间开发秩序调整思路.研究表明:江苏大部分地区生态保护与建设空间耦合基本协调,不协调的区域主要分布于无锡、常州等地区,未来需控制该区建设空间的增长;重要湿地、水源涵养区和风景胜区等生态保护区的建设占用规模较大,未来空间开发应予以避让;农居空间占用生态功能保护区的面积较大,未来可通过合理调整农居空间的布局逐步减少对生态功能保护区的占用,降低生态系统压力,促进生态服务功能维护.

It is an important part of harmonizing the spatial relationship between development and ecological protection and development leading and space control to adjust the spatial arrangement of industry and town according to the distribution of ecological protection space. Taking Jiangsu Province as a case, matrix-analysis and spatial analysis method was applied to exploring the spatial coupling characteristic of ecological function protection area and construction land and status of the ecological function area occupied by space development based on extracting the information of ecological functional protection zones and construction land distribution, later, the adjusting route of space order was recommended. Conclusions were as follows： Firstly, the spatial coupling relationship between ecological function protection area and construction land was harmonious in most part of Jiangsu Province, but Suzhou and Wuxi cities were out of line, the construction land＇s expanding should be decreased in the future. Secondly, construction land occupies a large part of important everglade, riverhead protection area, and landscape area, spatial development should keep away from them. Thirdly, the ecological function area covered by the rural resident area is larger than other kind construction land, so the pressure on the region＇s ecosystem can be alleviated by the way of changing the spatial distribution of rural resident area in the further.
