Embodiment

[0029] Example: Reference Figure 1-2 As shown, the present invention provides a method for optimal scheduling of water resources based on hybrid plastic programming and its decomposition, which includes:

[0030] 1. Determine the threshold value according to the information of the original data, combine the large-scale system coordination decomposition algorithm to divide the entire geographical space of water resources into several irrigation areas, and set the natural factors, geographical factors and artificial engineering factors that provide water resources as variables, and set these Variables serve as geographical attributes of regions. Divide the area into plots of equal size, divide the plot into grids of 500m*500m, and unify the attribute elements of each grid. Finally, these rasters are clustered according to their attributes, and the clustering ensures the neighborhood connectivity (that is, the neighborhood similarity) of the geographical area, so that the type ...

Abstract

The invention discloses a water resource optimum dispatching method based on mixed shaping plan and decomposition. The problem is decomposed through analyzing the special structure of the problem, a local solution after the decomposition is obtained, and then, the special structure of the problem is utilized to obtain the optimum scheme of the special problem. The water resource optimum dispatching method has the advantages that a geographical module is divided through clustering, a mixed shaping plan mathematical model is built, the special structure of the problem is developed, and in addition, the problem is decomposed into small independent problems, next, the decomposed local solution is obtained, then, the local solution is recombined by using the special structure of the problem, the optimum scheme of the specific problem is obtained, and in addition, the optimality of the scheme is proved.

Description

technical field [0001] The invention relates to the application field of geographic information water resource water supply dispatching engineering, in particular to a method for optimal dispatching of water resources based on hybrid shaping planning and its decomposition. Background technique [0002] China has a vast area of ​​arid regions, where crop yields are low and unstable due to the shortage of water resources. Because water resources are constrained by many conditions such as geographical elements and natural resources, the allocation of water resources in different regions is significantly different, but in the entire large geographical space system , the basic principle of optimal allocation of water resources is the same, that is, to maximize the benefits of water resources utilization, including economic benefits, social benefits and ecological benefits, among which economic benefits are an important factor in determining the construction of water conservancy pr...
