水源地示范建设探索与实践——以南京市浦口区长江桥林水源地一级保护区水源涵养工程为例

为建设南京市首个具有示范效应的水源地,南京市浦口区长江桥林水源地一级保护区水源涵养工程建设项目项目坚持“最小干预”的设计理念,充分尊重滩地原有地貌,改造并连通水系;采用沉淀→滤除悬浮物→湿地系统等协同作用净化水质;通过分析水文数据,选择耐水湿、低维护、易养护的植物进行水源涵养;结合巡查便道设计为水源地一级保护区提供必要的配套服务设施。工程实施后社会效益、生态效益、示范效益显著,为集中式饮用水水源地建设提供了有益的参考。

Exploration and Practice of Demonstration Construction for Qiaolin Water Source in Nanjing

In order to build the first water source with the demonstration effect in Nanjing, the construction project of water conservation engineering in the first-grade protection area of Yangtze River Qiaolin Water Source in Pukou District of Nanjing adheres to the design concept of "minimum intervention" to fully respect the original landform of the beach, and to reconstruct and connect the water system. The water quality is purified through the synergistic action of sedimentation, filtering suspended solids and wetland system. By analyzing the hydrological data, the plants that are resistant to moisture, low maintenance and easy to maintain are selected for water conservation. In combination with the design of inspection access road, the necessary supporting service facilities shall be provided for the first-grade water source protection area. After the implementation of the project, the social, ecological and demonstration benefits are significant, which provides a useful reference for the construction of centralized drinking water sources.
