摘要：
Soil microbial properties have been proved to be powerful indicators of soil quality. This study analyzed the changes in soil moisture content, soil bulk density and porosity, soil organic carbon, total nitrogen, and microbial biomass of Substrate in vegetation restoration of Rock Slope. The results showed that soil moisture, soil porosity, organic carbon (OC), total nitrogen (TN) and microbial biomass carbon (MBC), microbial biomass nitrogen (MBN) and C/N increased significantly, and soil bulk density decreased gradually compared with bare rock Slope. Therefore, the results suggested that the vegetation restoration of Rock Slope could improve soil quality.
