摘　　要：为了评价伊犁河流域的健康状况,应用鱼类生物完整性指数(F-IBI)建立了伊犁河流域河流生态系统健康评价体系。2012年-2014年在伊犁河流域设置了6个采样断面,进行鱼类资源调查。从36个候选指标中筛选了8个核心指标用于构建伊犁河流域F-IBI评价体系。通过分析评价,结果显示有1个采样断面处于极好的健康状态,3个处于好的健康状态,2个处于一般状态。伊犁河流域生态系统健康整体上处于好的水平。基于FIBI体系的健康评价结果与其他方法评价结果基本一致,这表明构建的F-IBI体系对伊犁河流域的健康状况评估具有良好的适用性,可作为伊犁河流域水环境监测的一种有效手段。In order to build an assessment criteria and standard of ecosystem health for Ili River, Xinjiang. The Fish - In-dex of Biotic Integrity （ F - IBI） was applied to evaluate the health state of Ili River. Fishery resources of 6 sites in Ili River were investigated from 2012 to 2014. Eight key metrics were selected from thirty - six candidate metrics to develop the final F - IBI system. According to the assessment criteria, it was determined that one site was excellent, three were good and two were fair. Overall, the water quality of Ili River belonged to a better state. Moreover, the assessment results based on the F - IBI were consistent with those from other biotic indexes. Thus, the proposed F - IBI system is suitable to the Ili River, and could serve as one effective measure of environmental monitoring in the river system.
