The invention discloses a water distribution method and system based on the characteristics of ecological gates. The method includes: calculating the water demand of each ecological gate water diversion benefit area and the unit ecological benefit of each ecological gate water distribution; formulating the total water volume at the reference section of the river section to be decided Constraints; NDVI, ecological sensitivity index and water shortage degree are used as classification indicators of ecological gates, and the method of systematic clustering is used to classify ecological gates with water shortage degree greater than 0 and water shortage degree less than 0; according to the ecological gate type and Set the water volume permitting coefficient of each ecological gate according to the water inflow; use the linear programming method to solve the actual water diversion of each ecological gate when the ecological benefit is the largest under different water inflow conditions. In this way, the present invention can coordinate the allocation of limited water resources according to the degree of water demand of many gates, benefit returns, etc., so as to obtain the maximum ecological benefits, and can provide decision support for relevant management agencies. is of great significance.
Description
technical field [0001] The present invention relates to the technical field of efficient utilization of water resources and environmental protection, and more particularly, to a method and system for water distribution based on the characteristics of ecological gates. Background technique [0002] In the vast arid and semi-arid regions of our country, river water is the main source of water for industry, agriculture and ecology, but the amount of influent water that can be reserved for ecological replenishment of the river basin after meeting the needs of industry and agriculture is very limited. When supplementing ecological water in some watersheds, in addition to relying on the seepage of the mainstream of the river, gates specially used for ecological replenishment are also built along the river to introduce the mainstream river water into the channel, through the seepage along the channel and the infiltration after the water flows out from the outlet. Supplement groundw...
