摘　　要：基于GIS和模糊数学理论,提出了工程移民安置区选择评价模型,为移民安置区选择提供了一种新的决策方法.该模型通过采用熵信息论建立了综合考虑主客观影响的复合均权法得到指标的权重,减少了指标权重确定的片面性;并采用GIS空间分析功能生成安置区的备选集,从根本上保证了模糊评价的数据源质量,使得评价结果更加科学准确.最后结合应用示例,对模型进行实例分析,结果表明该模型是有效的.Depending on GIS and fuzzy mathematics theory,a model for selection of resettlement area was proposed.This model provided a new method for decision making in area selection of resettlement.Combined with entropy theory,Compound-Evenness-Weight method was brought forward,which took both subjective weight and objective weight into consideration.The combination weight can effectively reduce the unilateralism of weight for decision.The model took advantages of GIS technology of spatial analysis to get the preparatory areas,which guaranteed the quality of data source and increased the accuracy of the evaluation result.Finally,an application case verified the validity of the proposed model.
