Problems solved by technology

These methods are not deep enough in the research on the eco-hydrological process and interaction mechanism of lake wetlands. Most of the ecosystem elements are analyzed independently, and the integrity of the ecosystem and the interdependence of internal elements are less considered.

Embodiment 1

[0043] This embodiment is a method for quantitatively calculating the ecological water demand of lakes and wetlands in arid areas, and the process of the method is as follows: figure 1 shown. The steps of the method described in this embodiment are as follows:

[0044] Steps to identify indicator species: indicator species and key populations in the food chain for identifying lake wetlands in arid regions, including:

[0045] Ecosystem structure analysis: starting from the integrity of the ecosystem, comprehensively considering the structure and food chain of the lake wetland ecosystem, and analyzing the growth characteristics of wetland vegetation, benthic organisms, fish, birds and other organisms in arid areas.

[0046] Ecosystem structure analysis is mainly based on literature research and field investigation, and finds the main animals and plants in the food chain in the ecosystem of lakes and wetlands in arid areas. The analysis objects include: inorganic environment, ...

Embodiment 2

[0095] This embodiment is an improvement of the first embodiment, and is a refinement of the correlation analysis method of the first embodiment. The correlation analysis method described in this embodiment is: the gray correlation degree method or the multiple regression method.

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 ...
