摘要
The authors studied the relationship between vegetation species and their covered rates, soil granularity, water content, vertical distribution of vegetation root systems at the vertical soil profiles in four coal mining collapse areas and two non-mining areas in the coal mine and conclude that coal mining collapses have no significant effect on land desertification and that the annual average rainfall of 415 mm may in the main meet the requirement for the moisture content for the normal vegetation growth in coal mining collapse areas. Such a conclusion provides a scientific basis for the prevention and control of land desertification during large-scale coal resources exploitation in mining areas.
