Nutrients carried in upstream rivers to lakes are the main cause of eutrophication. Building near-natural estuarine wetlands between rivers and lakes is an effective way to remove pollutants and restore the ecology of estuarine areas. However, for the existing estuarine wetland ecological restoration projects, there is a lack of corresponding evaluation methods and index systems to make a comprehensive assessment of their restoration effects. By summarizing a large amount of literature and doing field research, an index system was constructed by combining the characteristics of the near-natural estuarine wetlands themselves. It covered environmental benefits, technical management and maintenance, and socio-economic functions, and contained 3 systems, 7 criteria, and 16 indicators. The analytical hierarchy process (AHP) was used to determine the weights of each indicator. The top 5 indicators in order of importance were habitat diversity, total phosphorus (TP), coverage of aquatic plants, ammonia nitrogen (NH₃-N), and adaptation to the surrounding landscape. The above evaluation system was used for the comprehensive evaluation of the water purification project in the Fuhe estuarine wetland, Hebei Province, as an example. The results showed that the comprehensive score of the Fuhe estuarine wetland at this stage was 4.1492, and the evaluation grade was excellent. The effect of water purification and ecological restoration was good, and the selected technology was suitable and stable in operation. It had a greater positive impact on the surrounding economy and society and can be promoted and applied. The research results were important for clarifying the advantages and defects of the project and developing efficient and advanced restoration technologies.

基于层次分析法的近自然河口湿地评价指标体系构建及其应用

由上游河流携带到湖泊的营养物质是造成富营养化的主要原因。在江河湖泊之间建设近自然的河口湿地，是清除污染物、恢复河口地区生态的有效途径。然而，对于现有的河口湿地生态修复工程，缺乏相应的评价方法和指标体系来对其修复效果进行综合评价。通过总结大量文献和实地调研，结合近自然河口湿地本身的特点，构建了指标体系。涵盖环境效益、技术管理与维护、社会经济功能等3个制度、7项标准、16项指标。层次分析法（AHP）用于确定每个指标的权重。按重要性排序的前 5 个指标是生境多样性、总磷 (TP)、水生植物覆盖率、氨氮 (NH₃ -N），并适应周围的景观。以上评价体系以河北省府河河口湿地净水工程综合评价为例。结果表明，阜河河口湿地现阶段综合得分为4.1492，评价等级为优。水质净化和生态修复效果良好，所选技术适宜且运行稳定。对周边经济社会产生了较大的积极影响，可以推广应用。研究成果对于明确项目优势和缺陷，开发高效先进的修复技术具有重要意义。
