Problems solved by technology

However, few studies have simultaneously considered the equitable distribution of water resources between agricultural, household and industrial sectors
In addition, climate change intensifies and causes changes in the amount of water available, which inevitably leads to the risk of economic losses in the water sector
[0004] Therefore, the scarcity and fluctuation of water resources and the increase in demand for water increase the competition and conflict among water users

Embodiment

[0123] This example uses the proposed model in the Qujiang River Basin to conduct a case study to verify the practicability and rationality of the proposed multi-objective water resource allocation model, and to determine the water resource allocation strategy for the Basin Administration.

[0124] (1) Case background

[0125] The Qu River Basin is the largest tributary of the Jialing River. It passes through five municipalities directly under the central government in Sichuan Province - Bazhong, Dazhou, Nanchong, Guang'an and Guangyuan. In 2013, it covered a watershed area of ​​34,151 km2 and had 1,103,060 hectares of farmland and a population of 20,916,300. The Qujiang watershed provides water for domestic, agricultural, industrial and ecological sectors. Satisfying ecological water first, ensuring environmental sustainability, and then allocating water to the other three sectors.

Abstract

The invention relates to a water resources allocation technology, which discloses a multi-objective water resources balanced allocation method based on a conditional risk value constraint, which realizes quantitative fairness and risk controllable water resources allocation. The method comprises the following steps: a. Determining an objective function of multi-objective water resources allocation; B. Determine the constraint conditions of multi-objective water resources allocation; C. Constructing a global model of multi-objective water resources allocation according to the objective functionand constraint conditions; D. The global model of multi-objective water resources allocation is optimized. The invention establishes a multi-objective linear water resource allocation model, and helps decision makers to fairly distribute water resources to industry, agriculture, household and ecology through an optimized water resource allocation strategy, and simultaneously controls the risk ofeconomic loss.

Description

technical field [0001] The invention relates to water resource allocation technology, in particular to a multi-objective water resource balanced allocation method based on conditional value-at-risk constraints. Background technique [0002] Water shortage is a global problem that endangers human survival, affects regional socio-economic development and achieves sustainable development. Population growth and economic explosion have led to increasing competition among water users, in addition, extreme weather has led to uncertainty in available water supply and increased economic risk in water resource management. Therefore, fair and risk-controllable water resource allocation is urgently needed. Equitable access to water and the benefits of using it correctly are critical to eradicating poverty and promoting economic growth. In addition, the fairness of water resource allocation is closely related to social stability. Therefore, a scheme to ensure a stable, acceptable and ...
