Problems solved by technology

The hazards of rocky desertification are very serious, mainly manifested in the fact that it directly leads to a substantial reduction or even loss of land carrying capacity, aggravates natural disasters, seriously affects ecological security, leads to increased poverty in rocky desertification areas, and affects sustainable economic and social development. Desertification will lead to simplification of vegetation structure, simplification of ecosystem, leading to a sharp decline in biodiversity, etc.
[0003] In order to solve the above problems, the Chinese invention patent with the publication number CN104737866A discloses a land rocky desertification control method, which uses a combination of geotextiles and geocells. On the one hand, it can be directly used for water and soil in rocky desertification areas. Maintain, create conditions for large-scale afforestation, on the other hand, planting vegetation in geocells can rebuild the ecosystem, fix rocks and water from the roots, and prevent the expansion of rocky desertification; however, using geotextiles and geocells to fix water and soil On the one hand, the material consumption is large and the engineering quantity is large. On the other hand, the materials used in the geocells are engineering materials, and the reconstructed ecosystem is not a purely natural ecology. Natural restoration of ecology in degraded areas is not effective

Embodiment 1

[0035] A control method for a rocky desertification area, comprising the following steps:

[0036] S1. Soil preparation

[0037] 1) Digging pits: find low-lying places and depressions in rocky desertification areas, and dig pits with the help of digging equipment to form multiple pits scattered in rocky desertification areas;

[0038] 2) Clean up stones: clean up potholes and broken stones scattered in other areas, and collect them for later use.

[0039] S2. Build a frame

[0040] 1) Prepare branches: select branches from hard material tree species, the hard material tree species is Hongsenhuai, and the branches are completely lignified branches;

[0041] 2) Branch frame construction: transport the branches to the rocky desertification area, and set up the branches to form a branch frame. The longitudinal section of the branch frame is trapezoidal, narrow at the top and wide at the bottom; On the premise that the frame is supported from the side by the support, the branch ...

Abstract

The invention discloses a treatment method for a rocky desertification area. The treatment method includes: preparing soil, to be more specific, digging holes and cleaning rocks; building racks, to bemore specific, preparing branches and building branch racks; improving soil, to be more specific, building a planting slope, building water-retaining holes, and performing ground construction; performing ecological construction, to be more specific, building forest land, sowing grass seeds and laying mosses. The method has the advantages that by building the branch racks, setting the water-retaining holes and the planting slope and performing multilayer vegetation ecological construction, the natural restoration of the rocky desertification area can be promoted, natural ecology is built, long-acting treatment is achieved, and water retaining and soil fixation are achieved.

Description

technical field [0001] The invention relates to a treatment method for rocky desertification areas. Background technique [0002] Rocky desertification is the most serious ecological problem in karst areas in my country, and it is called "cancer of the earth". Rocky desertification mainly occurs in karst areas, and its causes are very complex, including natural factors, including: the rock foundation in karst areas is carbonate, which can easily cause soil erosion, and the concentrated and strong precipitation in karst areas provides conditions for soil erosion Wait. There are also social factors, including excessive firewood harvesting, excessive grazing, and disorderly industrial and mining construction and development. The hazards of rocky desertification are very serious, mainly manifested in the fact that it directly leads to a substantial reduction or even loss of land carrying capacity, aggravates natural disasters, seriously affects ecological security, leads to in...
