针对江淮丘陵区干旱缺水、面源污染及塘坝水生态系统退化等问题,2009年11月水利部立项开展了“江淮丘陵区粮食增产节水技术和生态系统重建”的课题研究,项目由安徽省·淮委水科院承担,安徽省淠史杭管理总局和合肥市滁河干渠管理分局共同参与。课题组开展了江淮丘陵区典型塘坝及水生态与蓄泄规律调研,分析了塘坝系统灌溉、抗旱能力的演变过程,提出了区域适宜的塘坝容量与种植结构,研究了库塘系统水资源联合优化调控模式,建立了塘坝水生态系统健康评估模型及富营养化预警评价模型,提出了塘坝水生态修复技术措施,为促进农田水土合理配置和塘坝水生态系统的修复提供了技术支撑。
In response to the drought and water shortage in the hilly area of Jianghuai Province, non-point source pollution and the degradation of Tangba aquatic ecosystem, the Ministry of Water Resources carried out the project research on “Increasing Grain Yield and Saving Water and Rebuilding Ecosystems in Jianghuai Hilly Region” in November 2009. It is undertaken by Anhui Huaibei Water Science Institute, Anhui Provincial Pishihanghang Administration and Chuhe Main Canal Management Bureau of Hefei. The research group carried out a survey of the typical pond dam and its ecology and storage and discharge rules in Jianghuai hilly area, analyzed the evolution process of the irrigation and drought resistance capacity of the pond dam, put forward the suitable capacity and planting structure of the pond dam, The model of health assessment and the eutrophication early warning evaluation model of pond dam ecosystem were set up. The technical measures for ecological rehabilitation of pond dam were put forward, which provided technical support for the rational allocation of soil and water in farmland and the restoration of pond dam ecosystem.
