Composite stony desertification ecological restoration method

Abstract

The invention discloses a composite stony desertification ecological restoration method which comprises the following steps: spreading soil and an artificial matrix on stony desertification land, dividing the stony desertification land, digging a blocking channel, and planting shrub plants and arbor plants in the blocking channel; grass seeds are sown or pasture is transplanted in the planting grids; a geonet is laid on the planting grids; and the forage grass is maintained by adopting a micro-spraying facility. According to the method, gridding treatment is conducted on the stony desertification land, soil improvement is conducted on the stony desertification land, the soil is solidified in the mode of digging the planting lattices, the isolation bricks are adopted for fixation, the soil adhesion is improved, water and soil loss is avoided, and the economic income can be increased by planting pasture in the planting lattices. The blocking channels are arranged at certain intervals, economic crops such as arbors or shrubs are planted in the blocking channels, and the capacity of stabilizing soil and maintaining water and soil is further improved.

Description

technical field [0001] The invention relates to the technical field of ecological environment restoration, in particular to a compound ecological restoration method for rocky desertification. Background technique [0002] Rocky desertification refers to the phenomenon of loss of surface soil, bare bedrock, loss of agricultural use value of land and degradation of ecological environment due to soil erosion. Rocky desertification mostly occurs in limestone areas, the soil layer is thin, and the surface presents the evolution process of gradually exposing rocks similar to desert landscape. The most direct consequence of the development of rocky desertification is the loss of land resources. And because of the lack of vegetation in the rocky desertification area, it is impossible to conserve water sources, which is often accompanied by serious drinking water difficulties for humans and animals. [0003] With the improvement of awareness of environment and ecological protection...

Problems solved by technology

And due to the lack of vegetation in the rocky desertification area, it is impossible to conserve water, which is often accompanied by serious drinking water difficulties for humans and animals.

[0003] With the improvement of awareness of environment and ecological protection, the restoration of the ecological environment of rocky desertification has become a means to change the ecology of rocky desertification. However, the current ecological restoration methods of rocky desertification are limited and cannot solve the problem of ecological restoration well. It is difficult to effectively restore the ecosystem by planting green plants, and problems such as poor vegetation adhesion and easy loss again are still prominent
