Determination method of irrigation district water delivery project

Abstract

The invention relates to a determination method of a water distribution scheme in an irrigation area. The method is characterized in that by determining the information of the irrigation area and crops, a crop irrigation mode is determined, the irrigation information in the irrigation mode is acquired, and a decision objective of a stage water distribution scheme in the irrigation area is determined; by constructing a linear planning model, an optimal solution of crop planting area in the irrigation mode is obtained; by exchanging the optimal solution with the decision maker, an adjustment scheme is acquired for figuring out a decision index matrix, and the adjustment scheme is sorted by calculations such as linear scale transformation, linear weighting, and the like; and finally, the stage water distribution scheme and a shift water distribution scheme in the irrigation area are determined. The determination method adopts advanced irrigating theories and technologies, perfects the decision process of irrigation water management, and improves the efficiency of the irrigation water management.

Description

technical field [0001] The invention relates to the technical field of decision support, in particular to a method for assisting irrigation management decision makers in irrigated areas to determine water distribution schemes in irrigated areas. Background technique [0002] At present, more than 5,000 large and medium-sized irrigation areas have been built across the country. Irrigation areas are the basic guarantee for national food security and the main base for the development of modern agriculture. Agricultural irrigation water accounts for 80% of the total available water resources, of which 60% is wasted. In addition to the factors of engineering technology, the lack of scientific decision-making of irrigation water is also an important reason. [0003] The main functions of decision makers in irrigation water management in irrigation areas include decision-making on the annual planting structure and the irrigation area of ​​each round in the irrigation area. But at...

AI Technical Summary

Problems solved by technology

But at present, the decision-making of decision-makers in irrigation districts is only the continuation of previous plans, and there is no complete decision-making thinking for formulating plans before the implementation of each plan

Secondly, the promotion of advanced irrigation theories and technologies is also one of the important responsibilities of decision makers in irrigation areas. However, most decision makers do not know much about them, which is why advanced irrigation theories and technologies are rarely applied on a large scale in most irrigation areas. one

[0004] At present, the existing studies on the optimization of planting structure in irrigation areas, water distribution in irrigation areas, and optimization of crop irrigation systems only use computers to calculate various models, and lack methods for assisting decision-making based on the main job functions and decision-making characteristics of decision-makers in irrigation areas.
