摘要
小流域治理效益的评价是一个多层次多指标的评价过程， 根据各评价指标特征值之间的变异程度， 利用信息论中熵这一工具， 确定各评价指标的权重， 以减小人为赋权的主观性。在此基础上， 建立数学评价模型，
The benefit evaluation about small watershed control is a multi level and multi index problem. According to variation degree among the characteristic values of evaluation indexes, the information entropy was used as a tool to determine the weight, so as to reduce the subjectivity of people. The model improved on the basis of information entropy can make the evaluation result more objectives.
