| 摘 要： | GIS的空间分析功能使其应用于选址时有独到的优势，现普遍应用的GIS多准则决策分析选址模型多为层次分析模型，其得结果为非劣解集，且没考虑交通网络。而距离是很多设施空间选址时必须考虑的因素，本文将基于层次分析模型的GIS选址方法和传统选址方法中的步行距离最小模型结合起来，得到考虑多种因素和路网结构下的步行距离最小的选址结果，使选址更符合实际，且通过实例验证该方法的可行性。

| Abstract: | GIS has unique advantages it is applied to selecting location, because of its powerful function of spatial a-nalysis.Now Multi criteria analysis model is always used in Selecting location, but the result is non-inferior solution,and haven’ t considering the transportation network.The distance is a very important factor that must be considered when we site some facilities.This essay combine the method of apply GIS、AHP and Minimum walking distance model of tradition-al method.It makes the result more scientific and more realistic.And this essay also verified the scientific of this meth-od. |
