Abstract

The invention relates to a quantitative calculation method for lake wetland ecological water requirement in an arid region. The method includes determining indicator species, searching for key restraining factors, building a model and calculating the lake wetland ecological water requirement. Compared with a water quantity balancing method, a curve relevant method, a minimum water level method and the like in the prior art, the method achieves the effect that structure and stability of an ecological system in the arid region are comprehensively considered. Compared with a functional method, the method achieves the effect that hydrological condition required by the indicator species around the lake wetland for growth and propagation is considered and is suitable for the lake wetland in the arid region. The method can be directly used for determining an ecological restoring target of the lake wetland in the arid region, guiding the implementation of wetland ecological water supplementation measures and has an important theoretical and practical meaning for basin water resource planning and configuration.

Description

technical field

[0001] The invention relates to a quantitative calculation method for ecological water demand of lakes and wetlands in arid areas, and is a method that can promote water resource management in river basins and ecological environment protection. Background technique

[0002] The traditional research on the ecological water demand of lakes and wetlands has not formed a complete calculation method, and its water demand is mostly determined by the water allocation of the water resources management department, emphasizing the importance of the flow of water resource allocation to the ecosystem; the calculation of the ecological water demand of foreign lakes and wetlands mainly According to the sensitive indicator species to be protected, such as fish's demand for water environment indicators, more attention should be paid to the fluctuation limit of water level when calculating. The calculation methods for the overall ecological water demand of lakes and wetlands ...
