摘要
Abstract
Scientific evaluation of river health status can effectively promote the management of small and medium-sized river systems and strengthen river management and protection.Five criteria layers and 15 indexes were selected,and the subjective and objective weights of each index were calculated by scale expansion method and improved entropy weight method.The fuzzy evaluation model was constructed to evaluate the health status of Jiangqu River in alpine river.The results show that the overall grade Ⅰ membership degree of the Jiangqu River is 0.811,which is in a very healthy state.The health level of the social service function criterion layer of the downstream L6 and L8 reaches is grade Ⅱ,and there are problems such as flood control failure.The comprehensive evaluation level of other river sections is grade Ⅰ,but it also reflects the problems of poor bank slope stability and reduced fish resources.The constructed model objectively reflects the river health status of Jiangqu River and provides scientific support for the management of Jiangqu River.The evaluation criteria and system can provide reference for the health evaluation of the same type of river.关键词
