湟水健康评价指标体系实践与探索

Practice and Exploration of Huangshui Health Evaluation Index System

目的:按照构建的湟水河流健康评价指标体系开展湟水河流健康评价,并识别湟水存在的主要问题,研究提出湟水健康的对策及建议。方法:以青海省湟水开展的河流健康评价工作为例,对评价指标体系的计算、评价方案制定等关键技术问题进行分析与研究。结果:湟水河流健康评价指标综合赋分为86.55分,等级为二类河流。结论:通过对结果进行分析可以看出,湟水在物理、化学、生物的完整性、社会服务功能可持续性等方面虽有一定程度受损,但目前仍处于健康状态,所以可以为其他河流的类似研究开展相关评价工作提供一定参考。

Purposes:The objective of this study is to carry out the health assessment of Huangshui River according to the constructed Huangshui River Health Evaluation Index System,identify the main problems existing in Huangshui,and put forward countermeasures and suggestions for Huangshui health.Methods:Taking the river health assessment work carried out in Huangshui Province of Qinghai Province as an example,the key technical issues such as the selection and calculation of evaluation indicators and the formulation of evaluation plans were analyzed and discussed.Findings:The comprehensive score of the health evaluation index of Huangshui River was 86.55 points,and the grade was Class II river.Conclusions:Through the analysis of the results,it can be seen that although the physical,chemical,biological integrity and sustainability of social service functions are impaired to a certain extent,Huangshui is still in a healthy state,at the same time,it provides a certain reference for similar studies on other rivers to carry out related evaluation work.
