摘　　要：以GIS和RS技术为支撑,利用德尔菲法确定影响城市建设用地生态适宜性的自然、社会经济和生态安全等因素,采用层次分析法计算相关影响因子权重。遵循生态保护优先的原则,建立了一套城市建设用地生态适宜性评价模型体系和方法,据此划分研究区城市基本生态控制区域,为合理有效地规划城市土地资源提供建议。With the implementation of the strategy for sustainable development in China＇s modernization, how to plan, develop and utilize the resources rationally, protect urban ecological environment with scientific and effective methods, and realize the rapid and healthy and sustainable development, has become a major issue increasingly concerned by people. In this paper, with RS and GIS as the technology support,Delphi-method was used to determine influential factors about ecological suitability in urban construction land, such as natural, social, economic and ecological safety factors etc. And the analytic hierarchy process （AHP） was used to calculate the weights of the related influential factors. Keeping the priority of the ecological conservation principle,a set of system and evaluation model for evaluation on ecological applicability of urban construction land were established. Using this model system and methods to define the ecological control area can provide important opinions about rational arrangement of urban land use.
