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 to carry out 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 low mountain and hill region pinus massoniana low-efficiency artificial forest near natural forest management method. The method comprises the following steps of S10, determining forest stand types, wherein the first forest stand is the forest stand needing to adjust the forest growth space and promote the forest growth, and the second forest stand is the forest stand needing to adjust the composition or density or structure; S20, selecting a tending method according to the forest stand types, wherein the first forest stand adopts target tree management and tending intermediate felling for transformation, and the second forest stand adopts tending intermediate felling or forest gap type felling for transformation; S30, selecting the tending time for tending according to the tending method, wherein target tree management is conducted before the sapling forest is closed to be the mature forest for felling, and tending felling and forest gap type felling can be conducted all year round. Accordingly, the near natural forest management method is adopted for transforming the low-efficiency forest, the transformation potential is huge, and the ecological benefitis good; the large-area low-efficiency forest condition in our country can be well improved due to near natural management, and sustainable management of the forest in our country is helped to be promoted, and sustainable development of the forestry is helped to be promoted.

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. ...
