本文通过对山区河流的基本特征研究,从生态功能和人类服务功能两大角度建立了山区河流健康评价系统,并基于投影寻踪理论构建了山区河流健康评估指标体系.以中国西南地区某典型山区河流为研究对象,本文对该河流水电开发前后的健康状况进行了研究.结果显示水电开发后河流综合健康状况较现状有显著提高.在此基础上,本文进一步通过对投影指标体系的结构特征分析,提出了维持河流健康的对策.

By analyzing basic characteristics of mountainous river systems, this paper established an index system of mountainous river health assessment from both an ecological service perspective and the perspective of meeting human needs, and has built a mountainous river health evaluation model based on Projection Pursuit theory. Taking a typical mountainous river in southwestern China as an example, this paper investigated its health status prior to and after hydropower development. The result showed that the comprehensive health situation after hydropower development is significantly better than that in the current situation. In addition, this paper proposed countermeasures for river health maintenance based on an analysis of structural features of the evaluation result.
