Abstract

Fuzzy matter-element was applied to evaluate comprehensive governance modes on sloping farmland and established a fuzzy matter-element model based on entropy weight coefficient method. In this model, take the comprehensive governance modes as matter-element things and construct compound fuzzy matter-element using the evaluation indexes and the corresponding fuzzy values of several modes. It can avoid the problem of weight allocation effectively that using the utility value which reflected the date themselves by information entropy. Finally, it will achieve sorting and selection of the best in all modes by comparing Euclid approach degree. From the evaluation of the comprehensive governance modes (conventional tillage, subsoiling + mole drain, subsoiling + furrow damming, subsoiling + mole drain + pipe drain, subsoiling + mole drain + furrow damming, subsoiling + mole drain + pipe drain + furrow damming), the result showed that subsoiling + mole drain + pipe drain + furrow damming was the best mode.

基于熵权系数法的模糊物元模型在坡耕地综合治理模式评价中的应用

应用模糊物元法对坡耕地综合治理模式进行评价，建立了基于熵权系数法的模糊物元模型。在该模型中，将综合治理模式作为物元事物，利用评价指标和各模式对应的模糊值构建复合模糊物元。利用信息熵来反映数据本身的效用值，可以有效地避免权重分配问题。最后，通过比较欧几里得逼近度来实现对所有模式的最优排序和选择。从综合治理模式(常规耕作、深埋+坑排、深埋+沟坝、深埋+坑排+管排、深埋+坑排+沟坝、深埋+坑排+沟坝、深埋+坑排+管排+沟坝)的评价来看，深埋+坑排+管排+沟坝是最佳治理模式。
