摘要
在新一轮土地利用规划启动的背景下,建设功能空间分区研究迅速成为当前关注的热点。在GIS数据库和空间分析方法支持下,采用综合指标评价方法定量评价县域尺度建设用地适宜性程度和生态限制性程度,并结合矩阵判断方法进行建设功能空间分区。在此基础上,以县域经济快速发展、建设用地供需矛盾突出的昆山市为例进行实证研究,将昆山划分为允许建设区、控制建设区、限制建设区和禁止建设区4类区域,并提出不同类型区建设用地布局的对策和建议。在允许建设区,鼓励产业和城镇集聚,鼓励高密度、高强度的开发建设;在控制建设区,控制开发建设活动类型,以对生态环境影响较小的开发建设活动为主;在限制建设区,不仅控制开发建设活动类型,而且限制开发建设规模;在禁止建设区,除生态环境保护必要的基础设施建设外,禁止其他任何开发建设活动。
On the background of a new round of land use planning in our country,spatial regionalization and land arrangement have become the focuses of current research issues.With the support of GIS database and spatial analysis tools,comprehensive quantitative evaluation methods for constructive land suitability and ecological restriction were established for county scale research,and a regionalization scheme of constructive land suitability was formed by the judgment matrix of constructive land suitability evaluation degree and ecological restriction evaluation degree.The research approach was utilized in Kunshan which has typical county economic development since reform and opening up,and has obvious contradiction between land supply and demand at present.According to regionalization results,the region in Kunshan could be divided into four types of constructive function area：the feasible construction area,the control construction area,the limitary construction area,and the prohibited construction area.Furthermore,countermeasures and strategies to land management of different types of regionalization areas were put forward to improve land use management and optimize the spatial layout of constructive land in Kunshan.The feasible construction area should encourage industries and towns agglomeration,and propose high-density and high-strength development;the control construction area should control the type of development and construction activities to lessen the impact on the ecological environment;the restricted construction area not only should control the type of development and construction activities,but also should limit the scale of the activities;the prohibited construction area should prohibit the construction activities except the necessary infrastructure facilities for ecological and environment protection.
