基于模糊综合评价法的水土保持工程生态效应评估研究OA

Although water conservancy projects have economic benefits,they also have a significant impact on the environment.To ensure the effectiveness of the soil and water conservation plan to be completed by 2025 in Yixing City,Jiangsu Province,it is necessary to accurately assess its environmental impact.An environmental impact assessment system suitable for soil and water conservation projects is established.To make up for the problems of excessive quantitative evaluation and lack of accurate quantification in existing evaluation methods,the core factors in the index system are determined by literature review and expert consultation combined with the characteristics of the Yixing project.Fuzzy mathematics is used to convert qualitative descriptions into numerical forms,and then the comprehensive evaluation value is obtained through attribute values and weights.The results show that this method can better overcome the influence of fuzziness and uncertainty in the ecological benefits of soil and water conservation,thereby providing a reference for the optimization of environmental protection management and value transformation of other projects similar to the Yixing project,and realizing a"green and sustainable"practice in Yixing.
