Abstract

The invention provides a vegetation ecological restoration method for a spoil area. The method includes: leveling the spoil area and keeping a preset flatness; laying a layer of soil to the surface of the leveled spoil area; improving the soil to make the soil suitable for agriculture and forestry; planting target vegetations on the improved soil, and using qualified treated domestic wastewater for irrigating the target vegetations according to a preset irrigation period. By the vegetation ecological restoration method for the spoil area, the soil is modified according to nutrients of the soil, then parameter information of the target vegetations and the soil is analyzed to obtain water requirements of the target vegetations according to the parameter information, and finally the target vegetations are irrigated according to the obtained water requirements. The vegetation ecological restoration method has the advantages that soil mellowing is accelerated, soil improvement is promoted, quickness in plant growth is guaranteed, water resources are saved, and environment friendliness and cost saving are realized.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a vegetation ecological restoration method in a spoil ground. Background technique [0002] A large amount of waste slag generated during the construction of hydropower stations requires a large site for centralized stacking. The stacking of these waste dregs has destroyed the original ecological environment of the dregs area, posing the threat of water and soil erosion. Therefore, after the project construction is completed, it is necessary to carry out necessary ecological restoration work on the slag yard, and accelerate the pace of ecological restoration through human interference. [0003] Most of the existing research on vegetation restoration in China is concentrated in areas with abundant rainfall and severe soil erosion hazards. The focus is on biodiversity and ecological community evolution. There are few studies on areas with high cold, little rain and barren...
