摘要：Conventional methods of land evaluation that use classicalmethods of hierarchieal classification and logic analysis todetermine land suitability classes have revealed some shortagesand they often break down in GIS. One of the reasons is that itis depended on the mental model which couldn't be recognized bycomputer in GIS, another reason is the functions which influentthe land classes are multiple and their variations are not inthe same steps, that makes us often fall down in hesitation indetermining the land level boundaries and mapping of landevaluation.Fuzzy reasoning and the mathematical models of fuzzy multipleassessment can overcome these difficulties and be datul forland evaluation in GIS. It's basic idea is from a single membership factor assessment to the multiple membership factors assessmentwith fuzzy reasioning and determining the weights of everyfactors with the AHP model.
