Embodiment 1

[0014] A non-ferrous metal smelting base adopts the above method, with an area of ​​200m 2 , the bottom and surrounding pool walls 1 are constructed of cement concrete, and the matrix is ​​made of non-polluting soil 2, filled in a W-shaped with high and low points, and the W-shaped wetland is divided into three areas: land area 4, shallow water area 5 and deep water District 6. Wetland plants 3 are mainly planted with cattails, with a planting density of 80 plants / m 2 , the water source uses local groundwater at a depth of 200m. During the period of use, the water source is regularly replenished to ensure that the water depth in the shallow water area is between 2-10cm. The wetland plants are harvested twice a year, and the amphibians are protected from toads. Compared with the toad in the polluted area, the birth rate increased by 7%, the death rate decreased from 74% to 0, the deformity rate decreased from 3% to 0%, and the metamorphosis rate increased from 90% to 100%. T...

Abstract

The invention discloses a W-shaped artificial wetland for protecting amphibians in a pollution site. The bottom of the wetland and the pond walls at the periphery of the artificial wetland are built by cement concrete. Pollution-free soil is used as a matrix, a filling mode is W type, and the whole wetland is divided into three regions which are a land region, a shallow water region and a deep water region respectively; reeds and cattails are adopted as main wetland plants and can be combined with other aquatic plants; local underground water is used as a water source; when the wetland is used, the water depth of the shallow water region can be ensured to be 2-10cm just by supplementing the water source regularly, and the wetland plants are harvested for 1-2 times each year. The wetland is simple in structure, easily available in materials and low in building expense, and can play an important role in amphibian protection.

Description

Technical field: [0001] The invention discloses a W-shaped artificial wetland used for the protection of amphibians in polluted sites, belonging to the field of animal protection. Background technique: [0002] With the deterioration of the ecological environment and the reduction of living space, amphibians are facing enormous pressure for survival, and the decline in the population of amphibians has become a hot spot of global concern. In recent decades, the problems of the ecological environment in my country have become increasingly prominent. Habitats have been severely damaged, biodiversity has declined sharply, and the survival and reproduction of amphibians are facing unprecedented challenges. The extinction rate of amphibians is as high as 200 times the normal rate. The reasons for the decline of amphibian populations are complex and diverse, among which wetland overuse, habitat loss and environmental pollution are currently recognized as the most important influenci...
