Problems solved by technology

Using existing tree species and plants to restore shrub forests without replanting to arbor forests. Cultivating target trees is the key to solving the problem. However, in current production practices, clearcut shrub forests are often used for reforestation, which is costly; or conventional mountain closures are used for afforestation. The method takes a long time, the effect is not significant, and it is difficult to form an arbor forest

Embodiment 1

[0038] The implementation site is located in Houlong Mountain, Xiayang Village, Taiyang Town, Lin'an City, Zhejiang Province, with an altitude of 50 meters and a southeast slope of about 25°.

[0039] target tree selection

[0040] In 2012, firstly, target tree species were screened in the shrub forest. According to a comprehensive investigation and statistics, there are 45 species of trees, including 20 species of trees and 25 species of shrubs. Arrange all tree species in this tree species list in order of priority development. Shrub species are ranked at the bottom, followed by small tree species, and large tree species are prioritized for cultivation. The subtropical pioneer arbor community to the top community evergreen broad-leaved forest is preferred. The typical tree species in the succession sequence were used as the target tree species. This prioritized list of tree species is a candidate list of target trees that are important for stand stability and productivity,...

Embodiment 2

[0059] The implementation site is located in Shuangkeng Village, Yuqian Town, Lin'an City, Zhejiang Province, with an altitude of 150 meters and a southeast slope of about 40°. The coverage of shrubs is 30%, and the height of shrubs is 2.20 meters.

[0060] target tree selection

[0061] First, screen the target tree species. After a comprehensive survey and statistics, there are 30 tree species, including 18 species of trees and 12 species of shrubs. Arrange all tree species in this tree species list in order of priority development. Shrub species are ranked at the bottom, followed by small tree species, and large tree species are prioritized for cultivation. The subtropical pioneer arbor community to the top community evergreen broad-leaved forest is preferred. The typical arbor tree species in the succession sequence is used as the target tree species. The target tree refers to the dominant tree in the main forest layer that plays an important role in the stability and pr...

Abstract

The invention discloses a non-reinforcement-planting modification method for southern difficult mountain shrubbery, and belongs to the technical field of forest management. The method comprises four steps including purpose tree variety screening, objective tree selection, ecological objective tree selection and forbidding. The method is simple and easy to implement, can remarkably improve possibility that the shrubbery grows into arboreal forest, reduces problems that ecological service functions are sharply decreased and the like because the shrubbery is clearly cut and comprehensive reinforcement planting is needed, and saves large-amount funds required in clear-cutting modification. The method utilizes current plants in the shrubbery for accurate tending and cultivation, the method has the advantages that woodland covering is continuous, the ecological system is stable, ecological service functions continuously rise and the like, and the method is suitable for promotion and application.

Description

technical field [0001] The technology of the invention belongs to the technical field of forest management, and in particular relates to a method for exempting replanting of shrub forests in southern difficult mountainous areas. Background technique [0002] Shrub forest is a vegetation type widely distributed in nature, and its distribution area in my country is 2×10 8 hm 2 , second only to grassland, but higher than forest. Compared with trees, the height of shrubs is generally less than 5m, and they grow in clusters with indistinct trunks. The natural shrub forests in the southern mountains are mostly degraded by evergreen broad-leaved forests after over-harvesting and utilization, and their productivity is low. It is the most widely distributed evergreen broad-leaved forest degraded type in subtropical regions. Significant changes have taken place in the species composition and system structure of the degraded shrub forests, resulting in a series of problems such as r...
