Water resource multi-dimensional equilibrium configuration system for inland arid regions

Abstract

The invention belongs to the technical field of water resource allocation, and particularly relates to a water resource multi-dimensional equilibrium configuration system for inland arid regions. Thesystem comprises a basic system layer, a model input layer, a mechanism recognition layer and a multi-target decision analysis layer. According to the system, a water resource is used as a control object; the total water consumption balance, the total water consumption balance, the water and soil balance, the water and salt balance, the water quantity balance and the water ecological balance are used as control targets; an eco-hydrological process is used as a key point of control; optimization-simulation-assessment are used as technical means; complex and changeable eco-hydrological index threshold values with non-uniform time-space distribution are continuously brought into a water resource development and utilization process of the inland arid regions; and an equilibrium solution of water resource configuration among a social goal, an economic goal and an ecological goal is searched for.

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...

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
