摘　　要：城市绿地适宜性评价是科学规划城市绿地系统的前提。以常州市绿地系统规划为对象,在野外调查和资料收集的基础上,根据主导性、稳定性、独立性和代表性原则选择城市绿地适宜性评价的影响因子,采用特尔菲法给定影响因子的权重,建立GIS系统管理下的各图层(影响因子)空间属性信息数据库,利用ArcGIS9.2空间分析功能,对常州市城市绿地规划建设用地进行定性定量评价,揭示常州市绿地布局的适宜性与限制性,以此确定常州绿地系统的布局空间和发展方向。结果表明,利用GIS对城市绿地适宜性进行评价,合理有效,实用性强,可丰富城市绿地系统规划的理论和方法。Land suitability evaluation has been widely used in the flied of agriculture, forest, urban expansion land and so on. This paper is a case study of the green space suitability evaluation theory and methods in Changzhou. Some evaluation factors are selected under the principle of dominance, stability, independence and typical, the weights of factors used for evaluation are decided by the method of Delphi, and the management of the various layers （factors） space at- tribute information database is created in GIS. By multi factors-overlay analysis in ArcGIS9.2, found the suitability and constrain distribution of green space in Changzhou city, which can be determined Cbangzhon green space system planning and development direction in future. Compared with the traditional planning methods, the results demonstrate that land suitability evaluation based on Geography Information System （GIS） is effective and feasible.
