Abstract

Vegetation blanket restoration of mine soils provides a diverse environment for soil microbes, but the effects of vegetation blanket cover on soil physicochemical properties, microbial structure, and diversity are not well understood, particularly in arid areas. In this study, high-throughput sequencing was used to examine the microbial community at Dafeng Mine, the Helan Mountains, Ningxia, China. Soil microbial communities were analyzed with four different materials: 100% straw, 50% straw–50% coconut, and 100% coconut vegetation blanket types, and a bare ground control (CK). The results showed that the contents of soil total nitrogen (TN), available potassium (AP), urease, and catalase were significantly increased in different types of vegetation blankets. High-throughput sequencing showed that the straw vegetation blanket increased bacterial diversity, while the coconut vegetation blanket increased fungal diversity. The main influencing factors of the dominant bacterial phylum were total nitrogen, catalase, urease, protease, soil water content (WC), soil organic carbon (SOC), and electrical conductivity (EC). The main influencing factor of the dominant fungal phylum was soil water content. These results show that compared with straw vegetation blankets, coconut, and straw–coconut vegetation blanket mulches are more likely to improve soil physicochemical properties, increase the diversity and abundance of soil microorganisms and improve the structural composition of the community, thus improving the soil environment in dryland mining areas. However, further research is needed as to which is the more significant environmental improvement, coconut or straw–coconut vegetation blankets.
