Abstract

The utility model discloses a W-shaped artificial wetland for protecting amphibians in contaminated fields. The bottom and surrounding tank walls of the W-shaped artificial wetland disclosed by the utility model are built with cement concrete. The matrix is pollution-free soil, filling way is W-type, the entire wetland is divided into three partitions, namely, a land area partition, a shallow water partition and a deep water partition respectively. Wetland plants mainly comprise reeds and cattails optionally in combination with other aquatic plants. Water source is local groundwater. When the W-shaped artificial wetland is applied, water source needs to be supplied regularly to ensure that the depth of the shallow water partition is 2-10cm and plants in the wetland are harvested for 1-2 times per year. The W-shaped artificial wetland disclosed by the utility model has the advantages of simple structure, readily available materials and low building costs and can play an important role in protecting amphibians.

Description

For the W type artificial swamp of contaminated site batrachians protection

technical field:

The utility model 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.

utility model content:

The purpose of this utility model 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

Bottom, the utility model wetland pond 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 50-100 cm is ballow.

The beneficial effects of the utility model are:

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 utility model is simple in structure, material easily obtains; structure expense is very low, aspect batrachians protection, can play a significant role.

brief description of the drawings:

Fig. 1 is structural representation of the present utility model

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

embodiment:

The utility model size can be determined with practical situation, and matrix 2 is used pollution-free soil, is filled to and has the W type dividing that has height, and W type wetland 1 is divided into three regions: first area is the ramp portion that both sides exceed the water surface, is land district 4; Second area is middle level land, and depth of water 2-10cm, is shoaling water 5; The 3rd region is region between shoaling water 6 and land district 4, and depth of water 50-100 cm is ballow 6.Water source uses local underground water.

Use the utility model only to need regular replenishment water source, ensure that the shoaling water depth of water is between 2-10 cm, wetland plant harvesting in 3 one years 1-2 time, easy to use, instant effect.

case study on implementation:

Case 1: certain non-ferrous metal metallurgy base, adopts aforesaid method, area 200 m ², bottom and surrounding pool wall are built with cement concrete, and matrix 2 is used pollution-free soil, is filled to and has the W type dividing that has height, and W type wetland 1 is divided into three regions: be respectively land district 4, shoaling water 5 and ballow 5.Wetland plant 3 for cattail be main, planting density 80 strains/m ², water source uses the dark following underground water of local 200m.Between the usage period, regular replenishment water source, ensures that the shoaling water depth of water is between 2-10 cm, 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%.

Claims

1. the W type artificial swamp of protecting for contaminated site batrachians, it is characterized in that: bottom, wetland pond and surrounding pool wall cement concrete are built, in pond, matrix is used pollution-free soil to be built into W type, 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 50-100 cm is ballow.
