Problems solved by technology
[0002] The comprehensive control of multiple water sources is the key technical means to solve the shortage of lake water resources and the deterioration of water quality in arid and semi-arid areas. How to jointly use multiple water sources, including precipitation, irrigation water retreat, and water diversion, to maintain the ecological water quantity and water quality requirements of lakes is a key issue for lake ecological protection and It is a key technical problem that needs to be solved urgently in restoration practice. However, the comprehensive model based on hydrodynamics-water quality-ecology is often neglected in the multi-water source regulation method for lake water environment restoration and improvement, and the water quality threshold and multi-water source regulation in lake multi-water source regulation The scientific determination of the ratio is difficult to quantify, which in turn affects the simulation accuracy of lake water environment indicators and the precise regulation and decision-making of multiple water sources
[0003] Based on the analysis of the ecological hydrological process of the river basin and the determination of the protection goals of lake water quality or water ecology, scholars often use a single clean water source to restore and improve lake water quality and water ecology, lacking comprehensive utilization of precipitation, water retreat in irrigation areas, diversion In addition, the application of the existing lake hydrodynamics-water quality model or water quality-ecological model in the process of multi-water source regulation lacks the research objects of hydrodynamics, water quality and water ecology. and most ecological models are often described at the level of functional groups and lack of description at the level of characterization, because: ① Research on the improvement and restoration of lake water quality and aquatic ecology by diverting water from a single water source While limited by water sources, various water resources are wasted, and it is difficult to restore the water environment while improving the utilization efficiency of water resources; ② there is a lack of a comprehensive simulation model for the coupling of hydrodynamics, water quality and ecology, and the ecological module lacks biological characterization The effective description at the level makes it difficult to accurately determine the water quality and water ecological goals of multi-water source regulation, and it is difficult to quantify the effectiveness and scientificity of multi-water source regulation. The lack of existing research makes it difficult to scientifically determine lake water quality and water ecological goals. The proportion of multiple water sources is difficult to determine scientifically, which makes it difficult for lake managers to propose accurate multi-water source control schemes. It can be seen that there is still a lack of more scientific lake multi-water source control methods based on hydrodynamics-water quality-ecological models
