A method for determining the regulation value of wetland water level suitable for waterfowl habitat

Abstract

The invention relates to a method for determining a wetland water level control value suitable for the habitat of waterfowl. The method includes the following steps: investigating the current situation of waterfowl resources, and determining the average occurrence of waterfowl species at different water levels in the control area in different months in the past five years; According to the living habits of various waterfowl species observed in different months, calculate the areas of different water depths required in different months in the controllable areas of artificial wetlands; determine the water level control values ​​in various areas of wetlands in different months; Relying on experience, it is not conducive to the current situation of bird habitat, and proposes a most economical method for determining the water level control value of constructed wetlands that meets the changes in the demand for different water level areas of wetlands due to changes in bird species, numbers, habitat and reproduction in different months , can enhance the suitability and attractiveness of wetlands to birds, scientifically protect wetland birds, and increase the number and diversity of 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
