摘　　要：作为长江中游重要的生态敏感区域和节点区,洪湖多年来一直承接江汉平原的调蓄与灌溉功能,剧烈的人类活动导致洪湖水体污染和生态系统退化加剧,洪湖水质的提升现已成为实施长江保护修复攻坚战行动的重点。通过系统剖析发现洪湖水质提升的关键问题在于入湖水质不达标、内源污染较重以及水生态受损严重3个方面。要解决洪湖的水污染问题,应坚持系统思维和流域视角,做好洪湖外源控污截污、底泥清淤、湖区和湖滨带生态修复以及水资源科学调度利用等工作,并推行包括洪湖及其支流流域河湖长制联防联控联治机制、生态补偿机制等在内的综合水质提升管理措施。As a critical ecologically sensitive area and a key node in the middle reaches of the Yangtze River,Honghu Lake has long served as a hub for water storage and irrigation in the Jianghan Plain.However,intense human activities have exacerbated water pollution and ecosystem degradation in the lake,making the improvement of Honghu Lake’s water quality a central objective of the ongoing Yangtze River conservation and restoration efforts.A comprehensive analysis reveals that the key challenges to enhancing the lake’s water quality lie in three main areas:inadequate inflow water quality,severe internal pollution,and degraded aquatic ecosystems.To tackle the water pollution of Honghu Lake,a systematic and basin-wide mindset must be adopted,encompassing effective measures such as controlling and intercepting external sources of pollution,sediment dredging,ecological restoration of the lake area and lakeshore,as well as scientifically allocating and utilizing water resources.In addition,comprehensive management strategies,including the establishment of an integrated water quality improvement framework,should be implemented.This framework would include a collaborative mechanism for joint prevention,control,and governance of Honghu Lake and its tributaries,as well as an ecological compensation mechanism.
