Problems solved by technology

Low-efficiency forest refers to the interference and destruction of strong natural and unnatural factors, the function of the forest stand system is reversed, the system components are deficient, the tree growth is slow, the quality is poor, the total vegetation coverage is low, and the soil structure under the forest is seriously affected. Erosion, the ultimate performance is that the function of water and soil conservation is poor, the entire forest ecosystem almost loses its self-recovery ability, and the forests with poor protection benefits or low economic benefits

Embodiment 1

[0043] A method for near-natural management of low-efficiency masson pine plantations in low mountain and hilly areas, comprising the following steps:

[0044] S10. Determine the type of forest stand; the first type of forest stand: the forest stand that needs to adjust the growth space of trees and promote the growth of trees; the second type of forest stand: the forest stand that needs to adjust the composition, density or structure;

[0045] S20. Select a tending method according to the type of forest stand; the first type of forest is transformed by target tree management and tending thinning; the second type of forest is transformed by tending thinning or gap felling;

[0046] S30. Select the tending time according to the tending method for tending; target tree management is carried out from young forest canopy to mature forest before harvesting; tending harvesting and forest gap harvesting can be carried out throughout the year.

Embodiment 2

[0048] This embodiment is based on Embodiment 1, in the step S20, tending is performed by tending thinning. In said step S20, the following steps are also included before adopting tending and thinning for tending:

[0049] S201. Determine the thinning intensity; determine the thinning intensity according to site conditions, initial planting density, and forest stand status;

[0050] S202. Selection and labeling of felled trees; the accuracy rate of tree selection and felling is required to reach more than 98%. Labeling should be carried out in the lush season.

Embodiment 3

[0052] In this embodiment, on the basis of Embodiment 1, in the step S20, adopting target tree management to carry out tending includes the following steps:

[0053] S21, determine the target tree density; figure 1 As shown, the target tree density is 100-400 trees / ha. Specifically, if the target tree is a middle-aged stand with good site conditions or a commercial forest, the target tree density can be increased to 200-400 trees / ha; if the target tree is a near-mature stand with poor site conditions or for public welfare For forests, the target tree density can be reduced to 100-200 trees / ha.

[0054] S22. Select a target tree; when selecting a target tree, select according to the principle of selecting the target tree and the criteria of the target tree. Among them, the principles for selecting the target tree are: 1. Avoid the forest road, the edge of the skidding road and the edge of the forest; 2. Relatively even distribution in the small class; 3. See more and compare ...

Abstract

The invention discloses a method for close-to-nature management of low-efficiency masson pine plantations in low mountain and hilly areas, comprising the following steps: S10, determining the type of forest stand; the first type of forest stand: a forest stand that needs to adjust the growth space of trees and promote the growth of trees ; The second type of forest stand: the forest stand that needs to adjust composition, density or structure; S20, select the tending method according to the type of forest stand; Thinning or gap harvesting is transformed; S30, select tending time according to the tending method; target tree management is carried out before harvesting from young forest canopy to mature forest; tending logging and gap logging can be carried out throughout the year. The present invention adopts the method of near-natural management to transform low-efficiency forests, and its transformation potential is huge and the ecological benefits are good; the situation of large-area low-efficiency forests in my country will be improved due to near-natural management, which will help promote the development of forests in my country. Sustainable management and promotion of sustainable development of forestry.

Description

technical field [0001] The invention relates to the technical field of forest ecological restoration, in particular to a method for close-to-nature management of low-efficiency masson pine plantations in low mountain and hilly areas. Background technique [0002] The evil consequences of ecosystem disturbance and destruction by human factors have become a prominent and major problem facing the world today, and have attracted widespread attention from all over the world. The theory of restoration and reconstruction of degraded ecosystems and its application technologies have attracted much attention. Low-performance forest is one of them. Low-efficiency forest refers to the interference and destruction of strong natural and unnatural factors, the function of the forest stand system is reversed, the system components are deficient, the tree growth is slow, the quality is poor, the total vegetation coverage is low, and the soil structure under the forest is seriously affected. ...
