在定义西藏河流健康的基础上,构建河流生态系统健康评价指标体系:河流水文形态、河岸带、水体理化性质、水生物和社会经济功能5个一级指标和20个二级指标.根据不同区域西藏河流的特点,将河流生态系统健康评价标准划分为藏东南河流、藏中南河流、藏西北河流和藏东北河流4种;建立了河流健康综合评价模型.对位于林芝地区的巴河进行评价,得到该河健康评价结果为中等的结论.西藏河流所处地理位置、气候条件的差异导致河流健康评价标准的差异,针对不同区域河流特点所确定的标准更符合实际情况.

Based on the definition of river health in Tibet, a river ecosystem health evaluation index system was built, covering the five-level indicators, i.e. the shape of river hydrology, the riparian zone, the physical and chemical properties of water bodies, water, biological and socio-economic functions and 20 secondary indicators and characteristics of the regions covered by rivers in Tibet. The river ecosystem health evaluation criteria were divided into categories for the rivers in southeastern Tibet, central south Tibet, northwestern Tibet and northeastern Tibet. A comprehensive evaluation model was established for river health. Evaluation of the Ba river in Nyingchi concluded that its health was moderate. Tibetan rivers and their geographical locations, climatic conditions and other differences lead to the differences in their health evaluation criteria and the criteria established in accordance with the characteristics of different river regions are more in line with the actual situations.
