Grassland region open pit mine vegetation restoration method

Abstract

The invention discloses a grassland region open pit mine vegetation restoration method. The grassland region open pit mine vegetation restoration method comprises the steps of landform consolidation,soil improvement, vegetation establishment and construction, maintenance and management, and the like. According to the grassland region open pit mine vegetation restoration method, on the premise ofkeeping the original landform and plant communities of a restoration region as much as possible, the landform is levelled, and soil improvement is conducted by means of soil structure improvement, nutrient replenishing and acid-base property adjustment, so that soil in a mine region is suitable for planting; and by conducting cross sowing on local native plants in a grid mode, the growth rate andthe survival rate of the plants in the restoration region can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of vegetation restoration in mining areas, in particular to a method for restoring vegetation in open-pit mines in grassland areas. Background technique [0002] The mining industry plays an important role in China's national economy. With the development of my country's economy and the increasing demand for mineral resources, the development and utilization of coal resources have caused a series of ecological and environmental problems. In recent years, with the continuous expansion of the mining of mineral resources, considerable negative impacts have been exerted on the ecology and environment of grassland areas, such as the decline in the quality and yield of grassland pastures, the loss of plant community biodiversity, the decline of groundwater levels, soil and vegetation Changes in structural composition, soil erosion, and frequent sandstorms have led to the deterioration of grassland ecology and seri...
