| 摘 要： | 随着城市化和工业化进程的加快,经济发达地区大量的农业及生态保护用地被侵占,开发可持续性受到威胁.从协调经济、人口、资源、环境相互关系出发,空间开发强调因地制宜,即让开发成本低、资源环境容量大的地区承担高强度的工业化和城市化等社会经济活动;而让生态价值高、开发难度大的区域承担农业和生态维护功能.土地开发适宜性分区,以生态-经济为导向,借鉴已有区划方法,采用要素层关系层逻辑层应用层的技术路线,评价适宜各单元的开发强度,划分开发与保护空间.将这一方法运用于江苏省的案例研究之中,以县和省辖市市区为基本评价单元,通过选择自然生态与经济社会两方面的指标,综合分析生态和经济重要性指数,将江苏全省划分为优先开发区域、适度开发区域、适度保护区域、优先保护区域和灰色区域等五大类型区.这一结果可以作为引导空间开发秩序、实施区域建设空间管制的重要依据.

| Abstract: | Along with the highly speedy urbanization and the industrialization in China,the contradiction between economic growth and ecological protection is more evident than ever before.The disordered land utilization has led to land overuse and natural ecological destruction.However,the regionalization of potential land use is a useful path to provide the scientific groundwork and guide of land exploitation and protection,i.e.,some areas shine in exploitation of industrialization and urbanization while others may need agricultural and ecological conservation.According to the technical route from factor layer,to relationship layer,to logic layer and finally to application layer,the method of regionalization,such as how to choose and analyse the ecological and economic factors and how to integrate the ecological and economic significant value by the method of classification matrix,has been discussed.After that,Jiangsu Province has been taken as a case for the regionalizaion of potential land use.Taking the counties and cities as the basic evaluating unites to apply the evaluation of ecological and economic significant value,Jiangsu Province is divided into feasible development area,limitary development area,moderate conservation area,prohibited exploiting area and elasticity gray area by the methods mentioned above,and then the spatial development direction and the management demand for each area has been advanced.That is a very important base for leading the order of spatial development and controlling the regional space. |
