Embodiment 1

[0040] The borrow area for embankment construction in a certain northern area is selected as forest land, covering an area of ​​62.4hm 2 , which belongs to flat land borrowing. After borrowing, the ground presents a huge borrow pit, the soil is exposed, the soil erosion is serious, the fertility of the soil is reduced, the land structure is destroyed, the vegetation is seriously damaged, the structure and function of the ecosystem are seriously affected, and the ecological environment is seriously damaged. .

[0041] In order to improve the ecological environment of the borrow field, the following implementation steps are adopted:

[0042] 1. Investigate the borrow site

[0043] Investigate the borrow yard to understand the basic conditions of the borrow yard, including: borrow yard topography, borrow yard topography, borrow yard geology, transportation roads around the borrow yard, original vegetation of the borrow yard, adjacent buildings, etc. Make preparations for ecolo...

Abstract

The invention discloses a method for ecological restoration of an earth taking area. The method comprises the steps of earth taking area reconnaissance, compiling of an earth taking area construction scheme, setting of a measurement control net, clearing of site obstacles, water drainage facility arrangement, side slope cutting, enclosure and the like. By adopting the method for ecological restoration of the earth taking area, the hidden danger of geological disasters existing after earth taking in the existing earth taking area and water and soil loss can be solved, and the influence of earth taking on the original ecological environment can be also effectively reduced by adopting the method.

Description

technical field [0001] The invention relates to the technical field of an ecological restoration method for a soil field, in particular to a method for restoring the ecological disturbance caused by borrowing soil from a borrow field, so that the borrow field can quickly restore the necessary functions of the ecosystem and achieve a self-sustaining state of the system. a repair method. Background technique [0002] During the borrowing process, the borrow site is damaged by various methods such as machinery, excavation, occupancy, waste, etc., the topography changes, the soil structure and soil composition change, resulting in soil pollution, water pollution, vegetation damage, water and soil Disturbance consequences such as loss will damage the local natural landscape and human landscape to a certain extent, and even cause the degradation of the ecosystem. [0003] Ecological restoration has received more and more attention and attention from the international community in...
