Problems solved by technology

Moreover, the traditional water resource allocation models are mostly based on several elements of the water cycle and ecological evolution, and the mechanism research on the interaction between the binary water cycle and the ecosystem in inland arid regions has not been deeply integrated into the water resource allocation model, and cannot meet the needs of inland areas. It is difficult to simulate the dynamic process due to the practical needs of multi-dimensional balanced regulation of water resources in arid areas and the response of different water resources development and utilization processes to the ecosystem in inland arid areas

specific Embodiment 1

[0034]The Tarim River is the largest inland river in China. Its basin is composed of nine major water systems. The main stream of the Tarim River has a total length of more than 1,000 kilometers. Under the influence of human activities, the evolution of the ecosystem in the Tarim River Basin is mainly "two expansions and four reductions", that is, the area of ​​irrigated oases in the upper reaches of the basin and the area of ​​deserts in the lower reaches expand, while the transition zone between the two: forest land and grassland , natural waters and biological habitats are shrinking. Under the "natural-society" dual water cycle, large-scale soil and water development and unreasonable water resource allocation pattern have caused changes in social water cycle fluxes such as total water consumption and total water consumption in the basin, which in turn has a negative impact on water and soil, water-salt and Eco-hydrological processes such as water ecology will be affected. ...

Abstract

The invention belongs to the technical field of water resource allocation, and specifically relates to a multi-dimensional balanced allocation system of water resources for inland arid regions. The system includes a basic system layer, a model input layer, a mechanism identification layer and a multi-objective decision-making analysis layer. The system takes "water resources" as the control object, takes "total water consumption balance, total water consumption balance, water and soil balance, water-salt balance, water volume balance and water ecological balance" as the control objectives, and takes "ecological hydrological process" as the control focus , using "optimization-simulation-assessment" as a technical means, constantly incorporating the complex and variable eco-hydrological index thresholds with different temporal and spatial distributions into the process of water resource development and utilization in inland arid areas, seeking the social goals of water resource allocation , the equilibrium solution between economic goals and ecological goals.

Description

technical field [0001] The invention belongs to the technical field of water resource allocation, and in particular relates to a multi-dimensional balanced water resource allocation system for inland arid areas. Background technique [0002] From the 1970s to the 1990s, with the increase of human activities, the large-scale development of water and soil resources made the ecological imbalance in my country's inland arid areas more serious, and caused a series of ecological environmental problems, the most typical ones being salinization and desertification. Phenomenon. Tracing back the rise and fall of oasis civilization in inland arid areas, it can be found that human activities have an important impact on the ecological changes of oases. Large-scale water and soil development and unreasonable water resources development and utilization allocation pattern have broken the original ecological balance of the watershed. Salinization and desertification (withered and decayed nat...
