Method for controlling stony desertification and restoring ecosystem of stony desertification region

Abstract

The invention discloses a method for controlling stony desertification and restoring an ecosystem of a stony desertification region. A technology for conserving water and soil in the stony desertification region, a surface vegetation restoring method and a technology for establishing artificial succession of rock vegetations are involved in the method. The method is characterized by comprising the following steps of: firstly, controlling the stony desertification and conserving water and soil to prevent water and soil loss and increase soil moisture; secondly, restoring surface vegetations and restoring the ecosystem by the technology for establishing the artificial succession of the rock vegetations; and finally, forming an ecosystem of artificial biotic communities in the stony desertification region, re-establishing the ecological environment in the stony desertification region, recovering the land production capability and preventing the soil and water loss. By the method for controlling the stony desertification and restoring the ecosystem of the stony desertification region, a benign and sustainable ecosystem based on a plurality of species of plants is established, and the sunlight, heat, air, water, stones, the soil and the plants form a multi-level, multi-species, benign and sustainable operating mode, so that the use rate of water and soil resources is improved, the effects of controlling the stony desertification and establishing the ecological environment are achieved, and the economic, social and ecological benefits are good.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and ecosystem reconstruction engineering, and relates to a method for controlling rocky desertification and its ecosystem restoration, in particular to a soil and water conservation technology in karst rocky desertification areas, and a method for surface vegetation restoration and ecosystem reconstruction. Background technique [0002] Stony Desertification refers to the destruction of surface vegetation, serious loss of water and soil, and decline of land production capacity due to unreasonable human social and economic activities under the natural background of tropical and subtropical humid and semi-humid climate conditions and karst development. Or loss, large areas of exposed bedrock or gravel accumulation of land degradation phenomenon, is also an extreme form of land degradation in karst areas. [0003] As of now, the total area of ​​rocky desertification in my country is ...

Problems solved by technology

The disadvantage is that it mainly relies on the three-dimensional network-like aerial frame, the water retention function is poor, and there are technical problems such as water storage and transportation.
