中国水利

复苏河湖生态环境是美丽中国建设的重要内容，是推动新阶段水利高质量发展的重要路径之一。科学评估河湖生态复苏成效是掌握河湖生态复苏状况的重要手段。本文在对河湖生态复苏内涵进行分析的基础上，统筹水资源、水环境、水生态等要素，按照可量化、可监测、可评估的原则，采用层次分析法（AHP）构建了包括水安全、水资源、水环境、水生态、公众满意度5个准则层12个指标的平原河网地区河湖生态复苏成效评估体系。选取水利部首批母亲河复苏行动试点河道丁堡河-江海河为实例，利用构建的基于平原河网特征的河湖生态复苏成效评估体系，在确定各评价指标权重的基础上，按照指标层、准则层、目标层逐层加权，计算得到丁堡河-江海河的生态复苏成效水平值。结果表明，丁堡河-江海河通过生态复苏后已达到健康水平，符合河流现状真实特征，但仍应持续加强河道长效管护，强化生态复苏的后续管理，实现河湖功能永续利用。

Restoring river and lake ecosystems is an important component of building a Beautiful China and one of the critical pathways for promoting high-quality development of water conservancy in the new stage. Scientific assessment of the effectiveness of ecological restoration of rivers and lakes is an essential means of understanding their restoration status. Based on an analysis of the connotation of river and lake ecological restoration, integrating elements such as water resources, water environment, and water ecology, as well as following the principles of quantifiability, monitorability, and evaluability, this paper employs the analytic hierarchy process(AHP) to construct an evaluation system for assessing the effectiveness of river and lake ecological restoration in plain river network areas. The system comprises 12 indicators across five criteria layers: water safety, water resources, water environment, water ecology, and public satisfaction. Taking the Dingbao River-Jianghai River, one of the frst-batch pilot rivers for the Mother River Revival Action initiated by the Ministry of Water Resources, as a case study, this paper applied the constructed evaluation system. After determining the weights of each evaluation indicator, the ecological restoration effectiveness level value of the Dingbao River-Jianghai River was calculated layer-by-layer weighted aggregation from the indicator layer, criterion layer, to the objective layer. The results indicate that the Dingbao River-Jianghai River has reached a healthy level after the ecological restoration, which is consistent with the actual conditions of the river. However, it remains necessary to continuously strengthen long-term river management and maintenance, reinforce the follow-up management of ecological restoration, and achieve the sustainable utilization of river and lake functions.
