山区河流健康评价体系研究OA

River health evaluation is an important foundation for comprehensively promoting the construction of happy rivers and lakes.Taking the Jiayi River in Luoding City,Guangdong Province as an example,this paper constructs a mountain river health evaluation system with"basin""water""biology"and"social service function"as the criterion layers,and evaluates the health status of the Jiayi River.The results show that the score of the"basin"criterion layer is 88.42,the"water"criterion layer is 82.83,the"biology"criterion layer is 81.60,the"social service function"criterion layer is 83.26,and the comprehensive evaluation score is 84.13.According to the river and lake health evaluation standard classification,the Jiayi River belongs to Class II rivers and lakes.On this basis,the scoring results of each indicator under"basin""water""biology"and"social service function"are further analyzed,the main existing problems of the Jiayi River at the current stage are sorted out,and corresponding countermeasures are proposed.
