Stand forest accurate target tree selective cutting selection technology

Abstract

The present invention discloses a stand forest accurate target tree selective cutting selection technology. A target tree is taken as a center, six trees nearest to the target tree are selected as subject trees, voronoi-thiessen polygon is taken as a picture composition basis, horizontal angle parameters are determined, competitive ratio is calculated, selective cutting rules are set up, the selective cutting target tree in the stand forest is scientifically and reasonably selected, the selective cutting target tree can be simply, fast, reasonably and quantitatively determined, operation is simple and convenient, and the selective cutting work target tree determine the efficiency can be effectively improved.

Description

1. Technical field [0001] The invention relates to a technology for selecting target trees for precise selective felling of forest stands, in particular to a technology for precise selective cutting of forest stands using 7 trees. 2. Technical background [0002] Forest tree production is one of the main economic benefits and has been valued for many years. Under normal circumstances, clear cutting is adopted, but the impact on the surrounding environment after clear cutting is huge, causing a series of environmental problems, which is especially unsuitable today when forest protection is strongly advocated, so selective cutting is often used. The forest can be regenerated through selective cutting. Practice has proved that selective cutting is one of the most important measures that are conducive to the sustainable use of forestry resources. protection, but also contribute to the conservation of biological diversity.

Problems solved by technology

[0004] In the traditional selective logging operation, the measurement is limited by the equipment, site conditions, and technical methods used. The workload is heavy and the cycle is long, so it is difficult to quickly obtain satisfactory results.

As an important technical method and means of forest survey, the angle gauge has been favored by forestry workers all over the world since it was invented. There are reports
