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

For the W type artificial swamp of contaminated site batrachians protection

Technical field:

The invention discloses a kind of W type artificial swamp for the protection of contaminated site batrachians, belong to protection of animal field.

Background technology:

Along with the deterioration of ecotope and the minimizing of living space, batrachians is faced with huge survival pressure, the decline of batrachians population quantity has become the focus of a global concern, in recent decades, China's ecological environment problem becomes increasingly conspicuous, the habitat of many species is seriously damaged, and species diversity falls sharply, and amphibian existence and breeding are facing unprecedented challenge.Amphibian extinction speed, up to 200 times of usual dispatch, causes that the reason complexity of batrachians population quantity decline is various, and wherein wetland excessive use, habitat loss and environmental pollution are current generally acknowledged significant effects factors.Have an appointment 1/3 batrachians of China is coerced by environmental pollution, and more than 80% species of being coerced are all distributed in wetland Region.Many organic pollutants (as petroleum hydrocarbon, volatile phenol), heavy metal (as copper, chromium, lead), agricultural chemicals (as G-30027) etc. exist that toxicity is lasting, difficult degradation, with features such as waters high workabilities, caused permanent toxicity to coerce to the batrachians in physical environment and this habitat.Have in various degree and the lopsided situation of quantity some contaminated site batrachianss.Mainly the foundation of wilderness area for the measure of batrachians population protection aspect at present.But setting up of wilderness area is consuming time, consumption power, too expensive, can not be applied to widely reality.

Summary of the invention:

The object of the present invention is to provide a kind of a kind of W type artificial swamp for the protection of contaminated site batrachians at contaminated site protection amphibian animal healthy living.

Technical solution

The present invention bottom and surrounding pool wall are built with cement concrete, and in pond, matrix is used pollution-free soil to be built into W type, plantation wetland plant.

Described matrix filling mode is W type, and W type wetland is divided into three regions: first area is the ramp portion that both sides exceed the water surface, is land district; Second area is middle level land, and depth of water 2-10cm, is shoaling water; The 3rd region is region between shoaling water and land district, and depth of water 50-100cm is ballow.

The invention has the beneficial effects as follows:

Cement concrete has effectively prevented water body loss; On wetland, plant the emergent such as reed and cattail and can effectively reduce moisture Evaporation; In matrix and water body, pollutent is up to standard, has effectively prevented that internal contamination is to amphibian harm; Inner three bigdoses of wetland can be for amphibian growth, grow, seek a spouse, breed, lay eggs, metamorphosis and healthy living provide good condition; protection batrachians avoids the murder by poisoning of contaminated site pollutent; the present invention is simple in structure, material easily obtains; structure expense is very low, aspect batrachians protection, can play a significant role.

Accompanying drawing explanation:

Fig. 1 is structural representation of the present invention;

Fig. 2 is the vertical view of Fig. 1.

Embodiment:

Size of the present invention can be determined with practical situation, and matrix is used pollution-free soil, is filled to and has the W type dividing that has height, and W type wetland is divided into three regions: first area is the ramp portion that both sides exceed the water surface, is land district; Second area is middle level land, and depth of water 2-10cm, is shoaling water; The 3rd region is region between shoaling water and land district, and depth of water 50-100cm is ballow.Water source uses local underground water.

Use the present invention only to need regular replenishment water source, guarantee that the shoaling water depth of water is between 2-10cm, wetland plant harvesting in year 1-2 time, easy to use, instant effect.

Embodiment 1:

Certain non-ferrous metal metallurgy base, adopts aforesaid method, area 200m ², bottom and surrounding pool wall 1 use cement concrete are built, and matrix is used pollution-free soil 2, is filled to and has the W type dividing that has height, and W type wetland is divided into three regions: be respectively land district 4, shoaling water 5 and ballow 6.3 kinds of wetland plants are planted take cattail as main, planting density 80 strains/m ², water source uses local 200m depths underground water.Between the usage period, regular replenishment water source, guarantees that the shoaling water depth of water is between 2-10cm, wetland plant harvesting in a year 2 times, and protection batrachians object is flower back of the body toad.Compare with zone of pollution flower back of the body toad then, natality improves 7%, mortality ratio reduces to 0 by 74%, abnormal rate is reduced to 0% by 3%, distortion ratio brings up to 100% by 90%, in each vegetative period, in flower back of the body toad body, ROS content reduces 16%-22%, and total antioxidant capacity improves 18%-35%, and hemocyte DNA damage degree reduces 23%-45%.The use of visible W type artificial swamp can be good at for the amphibian protection of contaminated site.

Claims

1. for the W type artificial swamp of contaminated site batrachians protection, it is characterized in that: bottom, wetland pond and surrounding pool wall cement concrete are built, and in pond, matrix is used pollution-free soil to be built into W type.

2. according to the W type artificial swamp for the protection of contaminated site batrachians described in claims 1, it is characterized in that: matrix filling mode is W type, W type wetland is divided into three regions: first area is the ramp portion that both sides exceed the water surface, is land district; Second area is middle level land, and depth of water 2-10cm, is shoaling water; The 3rd region is region between shoaling water and land district, and depth of water 50-100cm is ballow.
