基于河长制的河流健康与可持续利用评价

Evaluation of River Health and Sustainable Utilization Based on River Chief System

科学合理的河流健康评价方法能为河流管理者提供治理决策依据。依据河长制治河思路剖析河流健康与可持续利用内涵,构建适用于临沂涑河健康体系。并用AHP法和可变模糊计算河流健康分数。结果表明,2016年涑河健康与可持续发展评价结果为2.92,处轻度健康崩溃状态,当前面临主要问题是入河污染物过量和流域水生态问题。2020年涑河最优评价结果为1.54,河流处于较健康状态。表明河流自然属性完备与流域经济效益提升共同稳步增长,可实现河流的可持续利用。

In this paper,the connotation of river health and sustainable utilization is analyzed according to the idea of river chief system,and the health evaluation system suitable for Su River is constructed.The structure of the evaluation system is clear and reasonable,which can analyze the current limiting factors affecting river health and quantitatively predict river health results under different treatment scenarios by 2020.The results show that the evaluation result of health and sustainable development in 2016 is 2.92,which is a state of mild health collapse.In 2020,the optimal evaluation result of river basin is 1.54,and the river is in a relatively healthy state.It shows that the river's natural property is complete and the economic benefit of the river basin is improved steadily,which can realize the sustainable utilization of the river.
