Abstract

The invention relates to the forest industry and forest management and can be used for gradual logging. The purpose of the invention is to reduce the windfall of the cultivated forest and improve the conditions for the renewal of the cutting area. Released cutting area: wring into two or more delays nki 1,2 ... so that the length I of strips 3 does not exceed 250 m, chop the main portage 4 along the delta border or cutting area, divide each division into apiary strips 3 a width of 30-45 m and develop them by a perekolosnomnyy or kulisnym method with the condition of adjoining in adjacent areas nk I and 2 in inax order. Cutting trees are trunking along the portages 5 and the main drag 4 to the loading platforms 6. In subsequent methods of cutting, the scenes are cut down in the same order. The method allows, by increasing the productivity of the cutting area, to reduce the cost of timber harvesting. 2 or 9 (L

Description

Yu

And the wilderness belongs to the industry and forestry industry, and it can be used when carrying out forest cuttings.

I.U. ib of the invention - reduction of the windiness of the remaining tree stand and improvement of the conditions for the resumption of the cut logs.

FIG. I gfeivedena scheme for the development of a cutting area with inter-strip felling of trees; in fig. 2 - the same, with the kulisnoy felling of trees.

The method is carried out as follows.

The allotted cutting area is divided into two or more I and 2 cases, with the expectation that the length of 1 apiary lanes 3 does not exceed 250 m, the main fiber 4 is cut along the delta border or along the cutting area, each division is divided into strips

5 and mainline Volszhu 4 at loading areas C).

In the second and subsequent cuttings, depending on the number of methods, the remaining scenes are cut down in the same order.

The implementation of the proposed method allows, in comparison with a uniform method of gradual cutting by increasing the productivity of work on the development of the cutting area, to reduce the cost of timber harvesting.

Claims (1)

Invention Formula The method of gradual logging, which includes splitting the cutting area into strip-apiaries and the subsequent inter-strip or rocker clear felling of trees, characterized in that, in order to reduce the vegetation of the remaining tree stand and improve the conditions for renewal, the cutting area is cut 3 to 30-45 m 20 ivat on affairs nki and develop so that the cut-down strips of the apiary of one case are adjacent to the cut-down strips of the apiaries of the other case in a checkerboard pattern. by crossband or kulisnym method with the condition of adjoining apiary stripes 3 adjacent cases 1 and 2 in a checkerboard pattern. Cut down trees treleut on portages 0 five 5 and mainline Volszhu 4 at loading areas C). In the second and subsequent cuttings, depending on the number of methods, the remaining scenes are cut down in the same order. The implementation of the proposed method allows, in comparison with a uniform method of gradual cutting by increasing the productivity of work on the development of the cutting area, to reduce the cost of timber harvesting. Invention Formula The method of gradual logging, which includes splitting the cutting area into strip-apiaries and the subsequent inter-strip or rocker clear felling of trees, characterized in that, in order to reduce the windfall of the remaining tree stand and improve the conditions for renewal, the cutting area is developed into businesses and designed so  they do business and develop that the cut-down strips of the apiary of one case are adjacent to the cut-down strips of the apiaries of the other case in a checkerboard pattern.
