摘　　要：应用鱼类生物完整性指数(F-IBI)评价红水河梯级水库的生态系统健康状况。在各水库设置样本采样点,测定鱼类主要表型特征及水质主要理化因子,筛选并构建F-IBI评价体系。使用1、3、5赋值法计算各水库的IBI分值以评价各水库的生态健康状况。研究表明,红水河七座水库中,天生桥水库生态系统的状况表现为"较差",岩滩水库为"健康"状态,其余各水库健康状况为"良好"。总体上,红水河水系生态系统健康状况为"较好"。In order to assess the condition of ecosystem of seven step dropower Stations of Hongshui River, sampling points were settled in river reservoirs to examine phenotypic characteristic properties of fishes and the main physical and chemical factors affecting water quality, so as to filter out and construct the evaluation system of Fish-index of Biotic Integrity（ IBI） . The traditional step method was used to calculate the IBI value of each reservoir, and basing on this analysis, we evaluated the condition of each reservoir.According to this research, among seven reservoirs of Hongshui River, the ecological con-dition of Tianshengqiao Reservoir was“very poor”, Yantan Reservoir was“healthy” and other reservoirs were“good”.In general, the ecological condition of Hongshui River is“good”.
