| 中文摘要: |
| 以南水北调东线一期工程受水区涉及的89个县 （市、区） 为单元，采用模糊聚类分析法，根据受水区的生态水文特征，将受水区分为5个生态水文区。根据生态系统服务功能理论，提出调水为受水区生态保育措施、城市绿地与湿地生态系统带来的物质量与价值量的评估方法，计算出调水能够为受水区带来的生态环境效益总价值量为62.33亿元，其中生态保育措施、城市绿地与湿地生态系统的价值量分别为0.41亿元、37.67亿元和24.25亿元。研究结果可为制定南水北调工程生态环境保护及水资源可持续管理策略与措施提供依据。 |
| 英文摘要: |
| Implementation of the South-to-North Water Diversion Project will exert a profound influence on the ecological environment in water reception areas. According to the theory of ecosystem service fun-ction，the eco-environmental benefits attained by the East-Route Phase 1 Project in the reception areas are expressed as material and value quantity. By using fuzzy cluster analysis method，the 89 counties and districts in the reception areas are divided into 5 eco-hydrological regions according to their eco-hydrological characteristics. The material and value quantity assessment methods of eco-logical conservation measures，urban green land and wetland ecosystem are proposed，and corresponding values are calculated. It is found that the total eco-environmental benefit is 6.233 billion yuan，among which the value quantity of ecologicalconservation measures，urban green land and wetland eco-system is 0.041 billion yuan，3.767 billion yuan and 2.425 billion yuan respectively. The results provide the basis for formulating the strategies and measures of eco-environmental protection and water resources management of the Project. |
