Abstract:Taking the small Wuxiangsi Reservoir in Nanjing as the research object, a combined method of field reconnaissance, safety appraisal, water quality monitoring and quantitative analysis of hydrology and water resources is adopted to systematically sort out the existing problems of the reservoir, including potential flood control safety hazards, low coefficient of irrigation water utilization, unstable water quality compliance and imperfect management support system. Focusing on the two cores of efficient utilization of water resources and protection of water ecological environment, a water resource utilization system featuring intelligent irrigation and optimal scheduling of irrigation area digital twin is innovatively established, and a protection technology system covering whole-process prevention and control of non-point source pollution, construction of ecological buffer zones and restoration of water ecosystem is built. Meanwhile, the measures are perfected such as flood control compliance, development and utilization control, and intelligent management. The results can provide technical support for the reservoir to achieve the goals of flood control safety, stable water quality, ecological health and efficient management, and offer reference value for the coordinated public welfare functions and green development of similar small and medium-sized reservoirs.
