基于协调发展度的河流健康评价方法研究

Research on river health assessment method based on coordinated development degree

为评价河流系统的健康和协调发展状况,首先,从影响河流生态完整性要素和社会服务要素的角度出发,构建了包括水文资源、物理结构、水质、生物和社会服务功能等多个准则层的河流健康评价指标体系的统一框架;然后,借鉴社会经济与环境的协调发展度理念,建立了河流系统的协调发展度评价模型,并探索性地提出了基于河流健康管理的协调发展度等级标准;最后,以滦河为研究对象,对2011年滦河健康状态与协调发展状况进行了实证研究。结果表明,协调发展度模型既能评价河流系统的健康程度,又能衡量河流自然属性与社会属性的协调发展状况。

To evaluate the health and coordinated development of river systems, firstly, a complete systemfor river health assessment which includes water resource,physical structure,water quality,biology charac-teristics and social service is established;secondly,the concept of coordinated development in the sciencesof society and economy is used in this paper, and then construct the coordinated development evaluationmodel of river system,and put forward the criteria of the coordinated development evaluation model;final-ly, carried out the empirical research for the health coordination status of Luanhe River. The results showthat the coordinated development model can not only reflect the health degree of the river system,but alsocan measure the harmonious development of the natural and social attributes.
