Abstract

PROBLEM TO BE SOLVED: To provide a preservation method of a wood land capable of being early greened by on-spot native seeds and restraining wind blowing against woods on one side inclined plane. SOLUTION: After the trees 3 on one side inclined plane in the mountain 1 are cut down to remove, a tiered stand 2 is formed by cut, and for a method forming a green belt in a boundary 4 between the woods on one side inclined plane and woods on the other side inclined plane in the top of the mountain, the surface soil 12 formed by the cut is accumulated on the boundary 4, at the same time, a fence 14 is made of branches and leaves of trees to be cut down on the accumulated surface soil 12, and the fence 14 is used as a constructed buffer zone between a formation land and the wood land.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a method for preserving forest land.

[0002]

2. Description of the Related Art When developing golf courses, new towns, and highways, green areas and forest areas are often targeted areas. After clearing and removing green areas and tree areas,
Construction work for the land will be performed. in this case,
A greenery is created at the boundary between the cut and uncut areas.

FIGS. 2 (a) to 2 (c) show an example of a construction of a doll bed in a mountainous area. When a doll bed 2 is formed on one slope of a mountain 1 by cutting, the construction shown in FIG. All trees 3 growing on the slope at the position are cut down and removed, and as shown in FIG. At this time, the top of the mountain 1 is defined as a boundary 4 between the forest area on one side of the slope and the vegetation 5 on the boundary 4 by vegetation sandbags, vegetation mats, seed spraying, or the like, as shown in FIG. To create a green zone, and grow trees 3 on the other slope
To protect the land and preserve the land.

[0004]

However, in the above method, the following problems have been pointed out. First,
In many cases, non-native species are adopted as seeds for greening. In this case, the vegetation is poorly cultivated because it is not in harmony with the local ecosystem and climate, and the topsoil is cut off by cutting. Therefore, there is a disadvantage that it takes time to become a mature tree. Also, as mentioned above, if a slope such as a mountainous area is developed, the topography and ecosystem will change, and if a strong wind such as a typhoon strikes at a stage where the green zone does not grow sufficiently, the remaining one side slope will be In trees, the effect of suppressing strong winds is small, so fallen trees are likely to occur and cause serious damage.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a method for suppressing forest land in which early greening by indigenous local species and suppression of wind blowing into a tree on a one-sided slope are achieved. To provide.

[0006]

In order to achieve the above object, the method of the present invention is to cut and remove trees on one side of a mountainous area, cut the trees, and then, at the top of the mountain, remove the trees on the other side of the slope. In a method for preserving a forested land that forms a green zone at the boundary of the above, the topsoil generated by the cut is deposited on the boundary, and a fence is formed on the deposited topsoil by the branches and leaves of the felled timber. Is used as a buffer zone for land development and forest land.

Therefore, according to the above-described method, the fences formed can take measures against wind on trees on one side slope for the time being. In addition, it is possible to expect early growth of greening due to germination of seeds of local vegetation contained in the topsoil accumulated in the overburden due to aging, and greening due to mulch due to fence corrosion.

[0008]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 illustrates the method of the present invention. In FIG. 1, the same parts as those in the conventional example shown in FIG.
First, as shown in (b), the trees 3 on the one-side slope of the mountain 1 are cut down from the natural state shown in (a). The felled trees are sequentially accumulated in an appropriate accumulation place, where they are cut to an appropriate size by cutting or sawing.

[0009] Next, a doll bed 2 is formed by cutting at the logging site. In this case, as shown in (c), the construction work by the heavy equipment 10 is performed.

This cutting work is performed in a normal work form. In the present invention, in addition to the above, the topsoil 12 is scraped off prior to the formation work, and the topsoil 12 is removed from a forest zone on the other slope at the top of the mountain. Are sequentially scattered at the boundary portion 4 and are deposited on the boundary portion 4 as shown in FIG.

If the area of the peak is not sufficient, the peak may be cut flat and then be scattered.

After the completion of the construction, the above-mentioned branches and leaves which have been cut down to a predetermined size are transported to the boundary portion 4 and are used to form the fence 14 on the sedimentary topsoil 12 as shown in FIG. .

The fence 14 is made by a so-called digging method. No preservative treatment is performed. The material for binding between the fences is also a natural reduction type material such as ivy or scotch rope. A belt is created.

After the completion of the construction, for the time being, the fence 14 functions as a windbreak fence for the tree 3 that has been set on the other slope.

In the meantime, seeds of local vegetation contained in the topsoil 12 germinated and grown. On the other hand, the branches and leaves constituting the fence 14 are sequentially eroded and collapsed.
By returning to the inside, humus is further turned into a nutrient source, and by promoting the growth of local vegetation, generational changes with the fence 14 are made due to aging, and finally the boundary with the tree 3 on one side slope A greening zone will be created naturally in No.4.

[0016]

As is apparent from the above description, in the method for preserving forest land according to the present invention, local vegetation is used as a greening zone, so that there is little environmental change and the growth can be carried out at an early stage. In addition, until the green zone grows sufficiently, the fences using the cut trees can secure the windbreak function against trees on one side of the slope, so there is no danger of falling down due to strong winds and sufficient conservation can be performed. In addition, eutrophication of the green zone can be achieved by natural collapse due to corrosion.

Further, according to the method of the present invention, since all the materials for forming the green belt are locally procured, the material costs can be reduced and the transportation costs for transporting the materials to the mountaintop can be reduced.
