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F-IBI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-Index 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.
