Description

Method and structure for building up crawfishes' habitat of spontaneous restoring type

The present invention relates to a method for constructing a natural restoring crayfish habitat, which seeks the habitation or restoration of a natural crawfish by constructing a habitat in which the crawfish can be inhabited in an environment-friendly manner, unlike constructing only an artificial building or complex .

Due to large-scale development projects, forests in many regions are damaged and many valleys are damaged. As the valley is damaged, crawfish, which have been commonly seen in the past, have disappeared, becoming stories of memories or fairy tales, and even after restoring rivers, crayfish cannot be found.

Past environmental restoration has been done with emphasis on completion and dimensions. Therefore, the habitats of living things and the creation of various ecological environments are not considered, and the flow of water simply takes the form of streams, such as concrete or retaining wall blocks.

Then, as interest in the natural environment increased, the emphasis was placed on the creation of an ecological environment with a variety of biological spaces similar to the natural environment, not just rivers, which considered only the dimensions and the function of completion. However, even in these changes, only the focus on the ecological environment that is observed externally, namely, the planting of the dike and the favorable environment for landscape construction, has not been considered for the aquatic ecosystem that lives in the river.

Recognizing these problems, biotope composition and related research on various biological habitats have recently been highlighted.

Looking at the conventional research on the environmental composition of the biological habitat, there is no patent for the habitat of the crayfish, and the general habitat for the habitat and the restoration method of the firefly habitat as a specific species is disclosed.

In addition, the environmentally friendly firefly restoration device disclosed in the Republic of Korea Patent Publication No. 10-2006-0025958 describes a firefly restoration system and its composition method. Specifically, the environmentally friendly firefly restoring device is an inlet and outlet for water inflow and outflow on both sides of the waterway where the curved and irregularities are repeated, and the fireflies are ecological ponds in which a habitat environment is formed so that fireflies can grow and reproduce. In addition, an inlet connected to the outlet of the ecological pond is formed on one side and a perforated pipe is formed on the bottom thereof, and there are a lot of natural materials and porous filter media for purifying water flowing from the inlet, and the water passes from the upper layer to the lower layer. After the sequential purification of the purge pond and the discharged water discharged through the bottom of the perforated pipe and the circulation system for supplying to the pond.

As described above, various types of biotopes have been formed as fish hideouts in rivers, insect biotopes using aquatic plants and shallow waters in ponds or wetlands, or eco-pathway biotopes with connectivity for network formation. However, the creation of biological habitats without considering the scientific approach or the watershed level is expensive to maintain after creation, and it is difficult to create a continuous population maintenance and habitat environment.

In addition, most of the habitats for the promotion of biodiversity are focused on creating various growth environments through the planting of aquatic plants, and other problems are also mainly focused on improving water quality.

In addition, most of the habitat restorations so far focus on the improvement of habitat environment through planting of aquatic plants or the development of restoration apparatuses that produce visible effects. It is rare that a habitat is created in accordance with the environment.

In the present invention, it is intended to provide a technology for creating a habitat for habitation so that there is no problem in environmentally friendly habitats, and new and efficient methods or measures are constantly required for the creation of such environmentally friendly habitats.

In addition, in proceeding with the creation of a natural restoring crayfish habitat of an embodiment of the present invention, the water tank composition step and the tree habitat area creation step is also possible to change the progress of the progress step.

First, look at the fleshing and ecological characteristics of crayfish.

Lobster is a freshwater crustacean belonging to the Decapoda lobster (Cambaridae), which is about 6.4 to 7.2 cm in length and about 2.9 to 3.2 cm in length except forehead horns. The body is covered with exoskeleton (crustacean). The back side is smooth and reddish brown. The calcareous or cartinous exoskeleton also protects the body and periodically peels off. The body is symmetrical and composed of many nodes, divided into three parts of head, chest and abdomen or two parts of head and abdomen. The head and chest are slightly flattened to the back and the abdomen is flat. The head has 1 pair of compound eyes, 2 pairs of antennae, 5 pairs of legs, a belly segment, and 5 pairs of swimming legs. The front big leg is made of tongs and is good at walking backward.

Lobsters eat snails, insect larvae, worms, tadpoles, carcasses of small animals, daphnia, moss, plants, earthworms, frogs, etc., preferring animal food to vegetable food, and are mostly nocturnal and active at night. In addition, it takes about 8 to 10 months for lobsters to hatch from eggs to adult lobsters through young and medium lobsters, which are fertilized in vitro and napliuas in egg shells of eggs nestled in the abdomen. ), Which is attached to the mother's belly with claws such as zoea and mysis, and leaves the mother one week later to crawl under water several times while growing. Lobsters also mate in the fall and lay eggs in the spring to breed, and the mother also shows maternal love to protect the babies awakened from their eggs with their legs.

 Egg → Crawfish → Medium Lobster → Adult Lobster

Cultivation of lobster habitats requires an accurate analysis of the lobster's habitat environment and characteristics, which must be created and restored based on this information. Therefore, it is important to look at the characteristics of lobsters first. Through accurate understanding of the characteristics of these lobsters, it is possible to restore the clean aquatic environment where lobsters can live upstream when restoring the aquatic environment. Invasion of living organisms can also create livestock in the sheltered neighborhoods.

Specifically, lobsters have been reported to favor such environments because they are inhabited in small ditches away from valley valleys, and inhabited under rocks, between gaps, under leaves, and in water.

Suitable for crayfish populations, the ditch is about 1 m wide, rich in stone, many decayed leaves, and the valley has an altitude of 200 to 400 m. In addition, the water temperature is about 5 ~ 20 ℃, which is cold enough to cool your hands, and the water contains floating substances and deciduous corrosives. In addition, for habitation of lobsters, ditches with large stones and logs are formed. Big stones should be of a size that cannot be easily moved by sudden flow increases or children playing in the ditch and should be surrounded by pebbles or gravel. Also, in the middle or at the edge of the channel, there are rocks, cows, etc., and there is a stone gap with a diameter of about 40 cm. In addition, a large number of stone gaps are formed by small and large stones, and it is better if holes are formed by logs that have fallen on the roadway.

As described above, the method for forming a natural restoring crayfish habitat for the natural restoring crayfish habitat 50 according to the present embodiment is divided into a plurality of steps, and each process will be described in detail below.

In the first ground waterproofing step, the slopes and bends are provided, and the ground for the crayfish habitat is formed to be waterproof and include a plurality of habitat gaps for lobster habitat.

To this end, first, dug deeper than the thickness of the ground to be ground through the ground waterproofing step, then pick out bad rock, gravel, boulder, and other rubble, and then harden it to solidify the ground (501) (P552). .

As mentioned above, in the natural restoring crayfish habitat 50 of the present embodiment, in the habitat area 520 formed as a whole, the inclined area 510 formed with a slope 510 'inclined with respect to a relatively flat surface. It includes.

The slope area 510 may be formed after completing the habitat area 520 forming a flat bottom as a whole, but in the present embodiment, the crayfish habitat 50 is constructed by including the slope area 510 in the ground waterproofing step. See an example.

The natural restoring crayfish habitat 50 includes a slope area 510 having a slope (510 ') of about 5 to 20 degrees, at least 5m or more, 0.3 ~ 2 m wide It is formed to have, the slope 510 ′ of the slope area 510 is formed to be inclined to about 5 to 20 degrees from the flat ground, it is preferable to install at least one water fall within 2 to 3 m.

In this embodiment, the natural restoring crayfish habitat (50) is about 7 degrees inclined to include about 2m of water, and the center of the 10m long crayfish habitat 50 having a width of about 1m description do.

After the ground 501 is compacted, the nonwoven fabric 502 'is formed on the ground ground 501 to form a nonwoven fabric layer 502 (P554).

In the present invention, in order to waterproof the bottom of the ground for the efficient composition of the natural restoring crayfish habitat (50), by adjusting the ratio of lime to earth-friendly aggregate, clay, or stone dust, the waterproof and chemical changes were investigated. Same as

<Table> Changes in Waterproofing Efficiency and Chemical Properties According to Steel Content

According to the survey, ocher, clay, and stone powder do not react chemically with water and produce no toxicity. In the case of the lecture, it is confirmed that the waterproofing efficiency decreases when the content rate is low as an important factor in determining the waterproofing efficiency, and when the content rate is high, the increase of alkali and the waterproofing layer are broken due to the environmental change due to the lack of fluidity. Therefore, in order to efficiently waterproof, it is preferable to mix the at least one selected from ocher, clay, and stone powder with lime within 20% by weight.

Based on the irradiation, at least one of natural soils such as mud, loess, clay, and stone powder is selected on the upper portion of the nonwoven fabric layer 502 to form a waterproof layer 503 having a thickness of about 20 to 50 cm. In addition to this, the waterproof layer 503 may be mixed with any one or more of the above-mentioned natural soils such as mud, loess, clay, and stone powder at a ratio of less than 20% by weight to further solidify the steel. It is also possible to formulate (P556).

Next, after covering the top of the waterproof layer 503 formed with ocher, the ground aggregate is covered by covering the fine aggregate with a predetermined thickness, for example, about 10 to 30 cm, to form a waterproof upper layer 504 (P558).

After the ground of the crayfish habitat 50 is formed to be waterproof through the ground waterproofing step, the ground including a plurality of habitat gaps or voids in which the crayfish can inhabit the upper part of the waterproofed crayfish habitat 50 area. The habitat site forming step of forming a.

In the present invention, the survival rate of the crawfish according to the main aggregate composition of the bed material was investigated in order to form the habitat ground for the efficient composition of the natural restoring crayfish habitat 50, the results are as follows.
