Abstract

Abstract

China's water conservancy engineering construction has gradually shifted from flood control to water ecological environment restoration, and engineering construction always plays an important supporting role. This paper took the construction of an ecological reservoir in the water source area of Reservoir in a typical dense built-up area in Shenzhen as an example. The effect of ecological reservoir interception on the improvement of the water environment in water source areas in a megacity with water shortage was studied through the methods of monitoring and model before and after the construction of the project. The results showed that all kinds of pollutants in the water source area met the standards, and the water quality was increased by 3.6 times on average after the completion of the ecological reservoir. When the initial rainwater was 110 mm and the normal rainwater was 40 mm, rainwater collected by the ecological reservoir can be overflowed into the reservoir. The model predicted that the water quality of the reservoir area under the condition of normal rain was better than that of the initial rain condition, and the initial rain and normal rain could significantly improve the utilization of water resources and the water environment. After the construction of the ecological bank was completed, the initial rain and regular rain will increase the water environment capacity by 4.7 and 3.3 times, respectively. This study provides a scientific basis for the research on construction of water source areas in developed cities with water-source and water-quality water shortages.
