Mining Subsidence-Induced Microtopographic Effects Alter the Interaction of Soil Bacteria in the Sandy Pasture, China

The microtopographic changes induced by coal mining subsidence caused a series of environmental problems such as soil erosion, and vegetation degradation in the area. However, corresponding influence on surface characteristic different parts slope was completely different. To understand mines their future ecological restoration, it crucial to investigate origin. relationship between microbial community diversity, structure, taxa area topographic locations Daliuta mine, Shannxi, China, determined high throughput sequencing molecular network analysis. bacterial communities, factors, physicochemical properties also investigated. We found new trait formed deteriorate living environment community. coverage, water content, organic matter, urease dehydrogenase activities decreased significantly ( p < 0.05). Although diversity did not differ significantly, dominant varied. networks representing structure function were totally middle top tend be more complicated, interaction species is obviously stronger than that bottom. bottom approached simplicity, weak interaction, predominantly cooperative, observed within modules. Meanwhile, double stress aridity lack carbon source enhanced capacity metabolize complex sources at slope.
