多层次模糊综合评价方法在生态补水方案选择中的应用

Eco-Replenishment Selection Program Based on Multi-Level Fuzzy Comprehensive Evaluation Method

摘要: 本文提出一种生态补水方案的多层次模糊综合评价模型。首先，构建生态补水方案的多级评价指标，分为环境和经济效益型两类。其次，对生态补水方案的成本和效率型指标，计算其隶属度函数，分别进行单层次模糊综合评价，在此基础上给出多层次评判结果。最后，以南通生态补水为例，验证了模型和算法的有效性。

Abstract: This article proposed a multi-level fuzzy comprehensive evaluation model for resolving eco-reple- nishment selection program. Firstly, multi-level indicators of eco-replenishment program which are divided into environmental and economic benefits are constructed. Secondly, the membership function is used to calculate all cost and efficiency indicators, and single-level fuzzy comprehensive evaluation could be obtained. Then, multi-level evaluation results are given. Finally, an example for ecological water in Nantong City is taken to verify the validity of the model and algorithm.
