Embodiment Construction

[0022] The present invention will be described in more detail below in conjunction with the accompanying drawings, so as to facilitate the understanding and application of those skilled in the art.

[0023] Such as figure 1 As shown, the structure of the binary planting matrix used for mine reclamation in arid areas constructed by the present invention is as follows from bottom to top: the bottom ecological geotextile 1 laid on the mine matrix, the thickness of the bottom ecological geotextile 1 paved on the bottom A water storage cavity layer 2 of 70-80 cm, an intermediate ecological geotextile 3 laid on the water storage cavity layer, and a planting layer 4 with a thickness of 30-50 cm spread on the intermediate geotextile 3 .

[0024] The specific construction methods include:

[0025] The first step is to clean up the grass-roots site where plants will be planted. After leveling, the slope angle should be less than 20°, and set control management signs;

[0026] The seco...

Abstract

The present invention discloses a binary planting matrix structure for mine reclamation in arid areas. The binary planting matrix structure for mine reclamation in the arid areas comprises a bottom layer of ecological geotextile laid on the mine matrix, a 70-80 cm thick water storage cavity layer spread on the bottom layer of the ecological geotextile, a middle layer of ecological geotextile laidon the water storage cavity layer and a 30-50 cm thick planting layer laid on the middle layer of ecological geotextile. A construction method is simple, raw materials are easy to obtain, cost is low,and the construction method has better economic and social benefits. By covering of the ecological geotextile and adding super absorbent resin, water-holding and moisture-preserving capacity of the matrix in the mining area under harsh environmental conditions can be improved, water storage capacity of the matrix in the mining area is greatly improved and survival rate of plants in the mining area is improved.

Description

technical field [0001] The invention relates to mine regreening, in particular to a binary planting matrix structure used for mine reclamation in arid areas, and also relates to a construction method of the binary planting matrix structure. Background technique [0002] The mine environment is a complex system, and the development of mineral resources will produce a series of environmental problems, especially in arid areas with fragile ecology. Due to the characteristics of large area, low reclamation rate, and small restoration scale, mine abandoned land will take a long time and be difficult if it is allowed to recover naturally. In this case, it is very important to implement effective mine reclamation matrix construction technology and improve the utilization rate of land resources. [0003] The main problem facing mine reclamation in arid areas is that the topsoil layer is destroyed, and there is a lack of medium, water, nutrients, etc. required for plant growth, resu...
