海河水利

河流健康评价可以识别河流的具体问题和“病因”，为治理保护提供精准的方向。依据国家和贵州省有关河湖健康评价指南，以赤水河干流为例，构建了“盆”“水”、生物和社会服务功能4项准则层、11项指标层的贵州山区河流健康评价指标体系，主要采用生物完整性指数的评价方法。结果显示，赤水河干流综合赋分为87.68分，为二类河流，处于健康状态。研究结论可为赤水河干流管理提供理论支撑。

River health assessment can pinpoint specific issues and identify their underlying causes, thereby providing precise direction for conservation and management. Based on national and Guizhou Province guidelines for river and lake health assessment, a health evaluation index system for mountainous rivers in Guizhou was established, using the main stream of the Chishui River as a case study. The system comprised four criterion layers—river basin, water, biology, and social service functions—and 11 indicator layers, with the Index of Biological Integrity(IBI) as the primary evaluation method. Results showed that the main stream of the Chishui River received a comprehensive assigned score of 87.68, classifying it as a Class II river in a healthy state. The findings provided theoretical support for the management of the Chishui River main stream.
