摘要

In this paper, descriptive statistical analysis, correlation analysis and principal component analysis were used to study the terrain factors such as slope position, slope, bulk density, total porosity and other soil factors, taking Bulianta coal mine (non-subsidence area, subsidence area of 1, 3, 8, 11 years) and Daliuta coal mine (non-subsidence area, subsidence area of 1, 2, 6, 13 years) The relationship between vegetation coverage and other indicators provides important theoretical basis for further discussion on vegetation restoration and site environmental factors of ecological vulnerability in Shendong mining area, as well as vegetation restoration and vegetation coverage expansion, so as to control the impact of soil erosion on vegetation growth and distribution and maintain ecological stability. The results show that the main factors affecting the effect of vegetation restoration are terrain height and slope position, followed by soil moisture status, and finally altitude. Therefore, in order to promote the growth of vegetation, improve the ecological environment of the mining area and make it stable, the slope and other topographic factors should be reasonably regulated. Reasonable land preparation measures can give full play to its terrain advantages, make the soil and vegetation symbiosis, so as to continuously improve the soil, maintain the healthy growth of vegetation, reduce the amount of water and soil loss, and promote the ecological stability of the mining area.
