| 分析不同时期秦岭黑河流域鱼类生物完整性的特点及变化情况，为该流域水生生态系统健康评价和西安市重要水源地的保护提供参考依据。以鱼类为研究对象，通过现场调查（2018年）和收集历史资料（20世纪80年代和90年代），应用鱼类生物完整性指数（F-IBI）对该流域生态系统健康状况进行评价。根据研究区域的鱼类生态特点，初步构建了包含18个指标在内的秦岭黑河流域鱼类生物完整性指数评价体系，通过分析归纳，对这些指标进行筛选，最终确定了8个指标用于建立评价体系。结果表明，20世纪80年代秦岭黑河流域F-IBI得分为57，生物完整性表现为“极好”水平；90年代F-IBI得分为18，表现为“极差”水平；2018年F-IBI得分为30，表现为“差”水平。与20世纪80年代的资料对比，秦岭黑河流域鱼类资源减少，种类组成趋向单一化，鱼类生物完整性呈下降趋势，黑河流域生态系统健康状况下降，相关部门应对厚畛子镇、陈河镇等关键源区加强管理。 |

| The fish-based index of biotic integrity (F-IBI) is a quantitative measure of the effect of human activity on biological activity, and is a reliable method for evaluating the ecological and environmental conditions in lakes, wetlands, reservoirs, estuaries and rivers. In this study, an F-IBI assessment system was developed for the Heihe River at Qinling, Shaanxi Province. The index was then used to analyze and evaluate the environmental health of Heihe River during different periods. The objectives of the study were to provide a reference for evaluating aquatic ecosystem heath in the Heihe River basin and conserving the water source of Xi’an City. The F-IBI assessment system for Heihe River was based on field investigations of fishery resources in January, May and July 2018 and historical data on the fish assemblage in the 1980s and 1990s. Eighteen candidate indices, representing different attributes of the fish community were selected, based on the fish species inhabiting Heihe River. After screening and analysis, eight indices were identified as suitable for the F-IBI evaluation system, and they fell into three groups: community composition, environmental tolerance, and feeding habits. The F-IBI scores for the 1980s, 1990s and 2018 were, respectively, 57, 18 and 30, indicating that ecological conditions were excellent in the 1980s, very poor in 1990s and poor in 2018. Compared with the historical data of the 1980s, the 2018 field investigation showed a marked decline in the F-IBI due to decreases in both fish stocks and species diversity. The ecosystem health of the Heihe River has been declining since 1980s and the relevant authorities should enhance management of critical source areas including the towns of Houzhenzi and Chenhe. |
