湖北省山区小流域生态清洁评价指标体系研究
Study on Ecological Cleanliness Evaluation Index System of Small Watershed in Mountainous Area of Hubei Province

生态清洁小流域建设围绕“生态”“清洁”两个重点，是对传统小流域治理模式的创新和提升，是保护水资源、减少水土流失、控制面源污染、建设美丽乡村的重要举措。本文通过查阅前人研究成果和相关法规、标准，从土壤环境、水环境、生态环境、人居环境4个方面选择了10个指标构建了湖北省山区小流域生态清洁评价指标体系。采用生态清洁指数计算水源涵养型、生态旅游型、生态农业型、宜居环境型小流域的生态清洁程度，最终将小流域生态清洁程度划分为很清洁、清洁、不清洁三个等级，为推进湖北省生态清洁小流域建设工作提供支撑。
The construction of ecologically clean small watershed focuses on “ecology” and “cleanliness”, which is an innovation and improvement of traditional small watershed governance. It is an important measure to protect water resources, reduce soil erosion, control non-point source pollution and build beautiful countryside. Based on previous research results and relevant regulations and standards, we chose ten indexes related soil environment, water environment, ecological environment and living environment for the ecological cleanliness evaluation index system of small watershed in mountainous area of Hubei province. The ecological cleanliness index was used to calculate the ecological cleanliness degree of water conservation type, eco-tourism type, eco-agriculture type and livable type small watershed. The ecological cleanliness degree of small watershed was divided into three grades: very clean, clean and not clean, which provides support for promoting the construction of small watershed in Hubei Province.
