摘　　要：河湖健康评价是河湖管理的重要内容,是掌握河湖健康状态、查找河湖问题的重要手段。本文以广东省东江干流为研究对象,以2017年和2022年数据为基础,从河流形态、水文情势、水质状况、水生生物、公众满意度5个方面对东江干流河湖健康状况进行综合评价和对比分析。结果表明,总体评价得分呈现下降趋势,由2017年的65.3下降到2022年的61.5,总体评价结果为健康状态;从目标层来看,功能状况得分增大,由2017年的60.2上升到2022年的67.7,均为健康状态;生态状况得分减少,由2017年的67.5减少到2022年的58.8,从健康状态转为亚健康状态。研究结果可为河流管理者科学、动态掌握河湖健康状况,进一步提出相应的管理对策提供有力支撑。River and lake health assessment is an important aspect of waterbody management and a key method for understanding the health status of rivers and lakes and identifying related issues.This paper focuses on the Dongjiang River mainstream in Guangdong Province,using data from 2017 and 2022.It conducts a comprehensive evaluation and comparison of the river’s health based on five aspects:river morphology,hydrological conditions,water quality,aquatic biology,and public satisfaction.The results show that the overall health score has decreased,from 65.3 in 2017 to 61.5 in 2022,with the overall health status still categorized as“healthy”.From the perspective of specific indicators,the functional status score increased,rising from 60.2 in 2017 to 67.7 in 2022,both classified as“healthy”.However,the ecological status score decreased from 67.5 in 2017 to 58.8 in 2022,shifting from“healthy”to“sub-healthy”.The findings provide valuable support for river managers to scientifically and dynamically understand the health status of rivers and lakes,and to develop corresponding management strategies.
