Description

Technical Field

[0001] The present invention relates to the technical field of ecological compensation quantification decision-making support, specifically a platform for ecological compensation quantification decision-making support for inter-basin water transfer projects. Background Art

[0002] With the development of society, the contradiction between the supply and demand of river water resources has become increasingly prominent, and the water use contradictions between provinces and departments are sharp. Inter-basin water transfer is an important measure to transfer water from basins with relatively rich water resources to basins with water shortages, so as to balance the water volume surplus and deficit between regions and meet the water resource needs of water-scarce areas. However, inter-basin water transfer often has a greater negative impact on the water transfer section. For example, before and after the implementation of the inter-basin water transfer project on the Orange River in Africa, the water transfer section of the Great Fish River in the South changed from an intermittent water area to a permanent water area, resulting in a major change in about 67% of the invertebrate communities in the water transfer section; the water transfer of Lake Texoma in the United States led to changes in the hydrological situation of the water transfer section and the water source area, and a large number of striped bass in the reservoir died in summer.

[0003] In recent years, domestic and foreign studies on the impact of inter-basin water transfer projects on the ecological environment have begun to be taken seriously, but generally focus on the impact of single parameters and single categories. For example, CN113689151B discloses a method for flood control risk assessment of the downstream area of a cross-river for an inter-basin water transfer project to quantitatively evaluate the flood control risk of the downstream area of a cross-river for an inter-basin water transfer project; CN111191886B discloses a method for evaluating the efficiency of inter-basin water transfer based on regional water resource simulation, which identifies the positive impact of inter-basin water transfer on the water resource beneficiary area and the negative impact on the water resource damaged area under the background of complex environmental changes by simulating the influence range and intensity of the water transfer project on the regional water resource pressure; CN112132486A discloses a method for evaluating the ecological environment impact of efficient utilization of water resources in the northwest inland river area, and its evaluation indicators mainly include water conservation, vegetation stability, soil conservation, soil quality improvement, etc. They generally lack in-depth research and comprehensive evaluation of the implementation effect and impact of water transfer projects.
