Method for determining regulation value of water level of wetland suitable for water birds to live

Abstract

The invention relates to a method for determining the regulation value of the water level of a wetland suitable for water birds to live. The method comprises the following steps: investigating the current status of water bird resources, and determining the average appearing case of all water bird species in a regulated region with different water levels in different months of the past five years;calculating different water depths and region areas needed by different months in the regulated area of the constructed wetland according to the living habits of all the water bird species observed indifferent months of the past five year; and determining the regulation value of the water level of every region in the wetland in different months. The most economical method for determining the regulation value of the water level of the constructed wetland, meeting the demands of the regions with different water levels in the wetland, varying with the species, quantity and the living and multiplying demands of the birds in different months, is provided to solve the present situation that existing wetland water level regulation generally lacks technical guidance, only relies on experiences and is not conducive to the living of birds, and the method can enhance the suitability and attractiveness of wetlands to birds, scientifically protect wetland birds and increase the quantity and diversity of the birds.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a method for determining a wetland water level control value suitable for the habitat of water birds. Background technique [0002] Wetlands are nesting grounds, wintering grounds and migration transfer stations for waterbirds. In recent years, constructed wetlands, as a project with both ecological restoration and landscape entertainment value, have been increasing in number and scale. At the same time, water level control devices such as sluice gates have been added to meet the needs of the project itself, tourists' hydrophilic entertainment, and wetland animals and plants. However, there is still a lack of technical guidance on how to set the water depth in different months in each area of ​​the constructed wetland, and how to adjust the water level in different areas in the most economical way to meet the needs of each period. Especially for many k...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a solution that satisfies the lack of basis for the determination of the water level of the existing artificial wetland and the lack of basis for the regulation of the water level in different periods, and it is difficult to meet the habitat demand changes caused by the changes in the species, quantity and habits of birds in different periods. The method of determining the water level control value of the constructed wetland based on changes in the species, quantity, and habitat and reproduction needs of birds in different months can increase the suitability and attractiveness of the constructed wetland to birds, and scientifically protect wetland birds. Increase the number and diversity of birds and improve the ecological restoration effect of constructed wetlands
