Field water resource optimal allocation method for reservoir irrigation area

Abstract

The invention discloses a reservoir irrigation area field water resource optimization allocation method, and the method comprises the following steps: S1, determining a water resource source, and dividing the water resource source into a backbone reservoir and a small reservoir; S2, performing water balance simulation calculation on the reservoir; S3, sampling the reservoir, performing standard detection on the sampled water quality, and screening qualified water quality; S4, performing water supply process simulation calculation of qualified water quality on field crop water supply, and determining irrigation water quantity; S5, constructing a water volume optimal allocation model, and determining water volume allocation time; S6, predicting the rainfall; S7, determining the allocation water quantity, and completing the optimal allocation of the field water resources of the reservoir irrigation area. The backbone reservoir and the small reservoir are jointly supplied with water to form a reservoir group; meanwhile, randomness of field rainfall is considered, so water resources in an irrigation area generate maximum economic benefits, the purpose of environmental protection and saving is achieved, normal water quality required by the irrigation area can be guaranteed, and it is guaranteed that the water resources are fully utilized.

Description

technical field [0001] The invention belongs to the technical field of agricultural resource allocation, and in particular relates to a method for optimal allocation of field water resources in reservoir irrigation areas. Background technique [0002] The purpose of implementing reservoir dispatching and field water allocation is to allocate appropriate amount of water resources to each field and various crops at an appropriate time, so that limited water resources can produce maximum economic benefits. If we can organically combine the optimal scheduling of reservoirs with the optimal water distribution in the field, the water resources will be distributed reasonably and effectively. However, most integrated optimization scheduling models only consider the water supply of backbone reservoirs, and very few consider the joint water supply of backbone reservoirs and local small water sources, which makes the optimal use of field water resources impossible. Therefore, the pres...
