Water resource allocation method and device

Abstract

The invention discloses a method and a device for configuring the water resource. The method comprises the steps of A, establishing an optimized model by taking land utilization maximization and water consumption minimization as a goal and taking surface water capacity constraint, available water capacity constraint of underground water, surface water irrigation proportion constraint, irrigation water requirement constraint, land utilization constraint, water reservoir capacity constraint and irrigation water capacity non-negativity constraint as constraint conditions; B, disassembling the optimized model into an upper bound sub model and a lower bound sub model according to a region interactive algorithm, introducing penalty coefficients through a type-2 fuzzy type reduction method, converting the upper bound sub model and the lower bound sub model into corresponding linear programming models, and solving the linear programming models; C, selecting different underground water use proportions, bringing the different underground water use proportions into the optimized model to compute, and obtaining a relationship between the underground water use proportions and a crop planting structure. By utilizing the method and the device, disclosed by the invention, the plan on water resource utilization under multiple uncertain conditions can be carried out, and a reasonable agricultural irrigation method can be provided.

Description

technical field [0001] The invention relates to the field of agricultural irrigation technology, in particular to the configuration technology for surface and groundwater resources. Background technique [0002] Agriculture is the source of basic means of subsistence on which human society depends, the premise and basis for further development of social division of labor and other sectors of the national economy to become independent production sectors, and the basis for the existence and development of all non-production sectors. The scale and speed of development of other sectors of the national economy are restricted by the level of agricultural productivity development and agricultural labor productivity. At present, while the world is developing its economy, it is facing problems such as: the variety and quality structure of agricultural products are not yet optimized, and the waste of agricultural water is serious. The severe shortage and degradation of agricultural l...

Problems solved by technology

For example, there is a lack of research and development to characterize the complexity of the agricultural system and multiple uncertain planning methods, and it cannot effectively take into account the uncertain factors of the agricultural system in terms of time and space, so it is difficult to give reasonable and effective solutions that take into account the needs of various aspects. decision-making options

In addition, in the application of agricultural system management, there is currently a lack of features that can effectively reflect system dynamics, diversity, and time and space. All these problems have become an important bottleneck that seriously restricts the research on the rational allocation of agricultural water resources.
