Embodiment Construction

[0018] A method for planting forest, shrub and grass vegetation in a karst rocky desertification area, comprising:

[0019] Step 1. Determine the vegetation succession stage

[0020] The main purpose is to use the principles of community ecology to understand the changes in the characteristics of community types, structures, compositions, and species in karst rocky desertification areas, to find out the ecological service functions of different vegetation, and to propose a compensation and matching structure strategy tailored to local conditions. The natural succession stages of vegetation in karst areas are divided into grassland-grass-shrub-shrub-tree-shrub-arbor forest stage, and the community characteristics of different stages are different during the succession process of karst vegetation from low-level to high-level (Table 1). The stage of vegetation succession needs to be determined first.

Abstract

The invention discloses a method for planting forest, shrub and herbaceous plant vegetation in a karst rocky desertification region. The method comprises the steps that 1, according to the change conditions of the community type, structure, composition and species characteristics of the karst rocky desertification region, a natural succession stage of the vegetation in the karst region is determined; 2, seed selection is carried out according to geology and soil conditions of the karst rocky desertification region; 3, plant combination matching is carried out by taking plant functional groupsas units; 4, according to geomorphological structure features of peak cluster depression of the karst rocky desertification region, ecological restoration and industrial development are comprehensively considered, and a three-dimensional matching mode of mountain space is established; 5, after matching, the forest, shrub and herbaceous plant vegetation is planted. The technical problems that an ecological system in the karst rocky desertification region degrades, the biological diversity is greatly reduced, and the water and soil loss is gradually intensified are solved.

Description

technical field [0001] The invention belongs to a method for planting karst vegetation, in particular to a method for planting forest, shrub and grass vegetation in a karst rocky desertification area. Background technique [0002] The ecosystem in karst rocky desertification areas has been degraded, biodiversity has decreased sharply, and soil erosion has gradually intensified, which has become a major ecological problem restricting the regional economic and social development of karst areas in Southwest my country. The ecological problems in this area have always been the focus and difficulty of my country's poverty alleviation, ecological restoration and reconstruction. However, due to human disturbance, the primary forests in karst areas have been damaged to varying degrees, forming different types of plant communities: grass slopes degraded by severe damage, to arbor forests close to primary forests, and between There are shrub grass slopes, shrub forests, arbor shrub f...
