中文摘要：

中国经济发达地区在工业化和城市化快速发展过程中，出现的地域开发过密和无序的状况，导致自然生态及农业发展受到较大破坏，可持续性受到威胁一以生态一经济为导向的地域开发适宜性分区，强调让开发成本低、资源环境容量大、发展能力强的地区承担高强度社会经济活动；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．以此促进经济、人口、资源、环境相互关系及空间秩序的协调．在借鉴已有区划方法的基础上．讨论了评价单元划分、评价指标选择与处理等技术方法，通过生态和经济重要性指数的矩阵分类分析，将苏州地域划分为优先开发、适度开发、适度保护以及禁止开发等四大类型．并针对不同类型提出分区管制要求．

英文摘要：

Along with the highly speedy urbanization and industrialization in the developed area in China, the sprawl of land use has led to the development disorder and difficulties in natural ecology and agricultural land protection, which will threaten the regional sustainability. However, the regionalization based on ecological-economic approach amphasizes that regions with low development cost, high carrying capacity of resources and environment as well as great development ability should undertake social and economic activities with great intensity; whereas those regions having high ecological values but are difficult to be developed should maintain fuctions of agriculture and ecology, so as to promote the harmonious interrelations among economy, population, resources and environment with spatial order. Referred to the existing regionalization, this paper discusses how to divide the assessed units, choose and manage the assessed elements etc. on the basis of traditional regionalization. The classification matrix has been applied for integrating the ecological significant value and economic significant value. As a case study, Suzhou city is divided into four types, i.e., preferential development area, feasible development area, moderate conservation area and prohibited exploiting area. Finally, this paper analyses the main function regionalization method and the policy guarantee of management at different areas.
