Moisture regulation structure for recovering vegetation in rock-soil residue field

Abstract

The invention provides a moisture regulation structure for recovering vegetation in a rock-soil residue field, comprising a residue stack bottom layer, a covering layer positioned on the residue stack bottom layer and a vegetation layer positioned on the covering layer. The covering layer is formed by a rock residue transition layer, a moisture interception layer and a mechanical reinforcing layer from inside to outside. The vegetation layer is formed by a matrix layer containing seeds or a matrix layer without containing seeds and a lawn nursery strip layer positioned on the matrix layer. The structure can ensure safe and stable residue stack, prevent landslide and soil erosion, effectively reduce water seepage of the residue stack, improve the ability of water retention, regulate the water ecological validity of the vegetation recovery structure system, strongly guarantee the moisture conditions required by vegetation growth and guarantee the recovery effect of the vegetation in theresidue field. The structure is mainly used for recovering the vegetation in the rock-soil residue field.

Description

technical field [0001] The invention relates to a rock-soil dreg field vegetation recovery structure in the field of water and soil conservation, in particular to a water control structure for rock-soil dreg field vegetation restoration. Background technique [0002] Water is the basic material condition for plant survival, and it is also an important ecological factor that affects plant morphology, growth and development, reproduction, and seed dispersal. Too little water in the environment will cause the plants to lose water and wilt; if it is too much, the aerobic respiration of the plant roots will be reduced, and the anaerobic respiration will be strengthened, resulting in alcohol accumulation and rot. Therefore, the presence of water and its ecological availability are the keys to ensure the healthy growth of plants. The rock and soil slag field is formed by the accumulation of discarded rocks, gravels and overburden weathered materials, which are loose and unstable, ...

AI Technical Summary

Problems solved by technology

The construction of this structure is quite time-consuming, laborious, and costly; moreover, the overlying soil layer is cohesive soil, although it has a certain function of intercepting water, but a large amount of soil needs to be excavated during construction, which not only destroys the local land resources, but also has great impact on solving the slag pile. Water seepage, water retention and other effects are not significant
