摘　　要：于2018年10—11月,对独龙江水系干流及支流的河流物理生境、水体理化性质和大型底栖动物进行调查,并根据独龙江自身特点,运用改进的河流健康综合评价指数对该地区生态系统健康状况进行了评价。结果表明:该地区调查样点中85.2%的样点处于健康状况,仅人口密集的乡镇附近健康状况处于亚健康水平,其中旅游业发达的独龙江乡健康状况最差。河流是水资源的重要载体,随着当地旅游业的不断发展,科学评价当地河流的健康状况可以为独龙江河流生态系统修复、水资源的合理开发利用及可持续发展提供重要的科学依据。We investigated river physical habitat,water physicochemical properties,and benthic macroinvertebrates in the main and tributaries of the Dulong River from October to November 2018.Based on the characteristics of the Dulong River,we developed a comprehensive assessment index of river ecosystem health to evaluate its ecosystem health.The results showed that 85.2%of the sites in the survey were in health status.The sites near the densely populated towns were at the status of sub-health.Specifically,the worst unhealthy sites were found in the Dulongjiang Township with the most developed tourism industry.Rivers are important carrier of freshwater resources.Under the background of continuous development of tourism,a scientific evaluation of river health status can provide scientific basis for ecosystem restoration,rational exploitation and utilization of water resources,and sustainable development of Dulong River.
