广义熵值与模糊集方法在农业生态环境支持度评价中的应用——以湖南省娄底市为例

The Application of General Entropy and Fuzzy set in Agriculture Ecology Environment Assessment——A case study of Loudi Hunan Province

在阐述娄底市农业复合系统特征的基础上,应用模糊集理论中的相对隶属度等概念,运用广义熵值和多因子模糊评判法构建综合评价模型,对娄底市农业生态环境可持续发展现状进行综合评价,依据评价结果分析娄底市农业可持续发展现状下的资源与环境方面的制约因子,探索适应环境变化的农业持续发展的对策.

Based on express the characteristic of agriculture complex system, in consideration of the concept of relative membership degree in the theory of fuzzy, With the method of general entropy and multi-factors fuzzy set,a synthetic evaluation model of sustainable agricultural development is constructed. Taking Loudi for an example,the present condition of the sustainable agricultural development is evaluated.In accordance with the limitations and by making good use of the advantages of agricultural development in Loudi city,strategies and concrete measures are proposed.
