A method for optimizing the allocation of water resources in a watershed

Abstract

The invention relates to a water resources distribution technology, which discloses a method for optimizing the allocation of water resources in a watershed, which solves the contradiction problem ofwater use in each region and each water use part under the condition of water resources shortage, and realizes the water use-equity, efficiency and economic water resources allocation. The method includes the following steps: a, considering the fairness of initial water rights allocation, the stability of water resources allocation system and the efficiency of water use rights allocation, constructing a multi-objective bi-level decision model of water resources allocation; b, solving the multi-objective bilevel decision-making model and allocating the water resources according to the result ofthe solution. The invention improves the fairness of water resources distribution in river basins, From the viewpoint of stability and economic efficiency, a multi-objective two-level model is established to consider the Steinberg game relationship between basin managers and zoning managers, and the Nash game relationship between different water use sectors, so as to help basin managers achieve sustainable water resources allocation and regional economic development.

Description

technical field [0001] The invention relates to water resource allocation technology, in particular to a method for optimal allocation of river basin water resources. Background technique [0002] In the distribution of water resources in real life, the initial water rights of a single basin are allocated by the basin manager to the district manager (ie, the primary market). Water sector (ie secondary market). In the case of sufficient water resources, the demand-based allocation scheme can meet the needs of various water sectors; however, for today's increasingly water-scarce society, the need-based allocation is obviously not applicable. [0003] In fact, two types of decision makers are involved in the process of assigning initial water rights and water use rights in a basin, namely, basin managers and zone managers. The river basin manager does not interfere with the allocation of water use rights by zone managers, but his initial The allocation of water rights will af...
