Abstract

Mining activities worldwide have resulted in soil nutrient loss, which pose risks to crop and environmental health. We investigated the effects of post-mine reclamation activities on soil physicochemical properties and microbial communities based on 16S rRNA sequencing and the further statistical analysis in the coal base in Peixian city, China. The results revealed significant differences in soil microbial relative abundance between reclamation and reference soils. Proteobacteria was the most abundant phyla in all seven mine sites regardless of reclamation age while considerable differences were found in microbial community structure at other levels among different sites. Notebly, Gammaproteobacteria, member of the phylum Proteobacteria, had relatively high abundance in most sites. Furthermore, Kendall’s tau-b correlation heatmap revealed that potentially toxic elements and other physicochemical properties play vital roles in microbial community composition.
典型资源型城市采后复垦区土壤特征及微生物反应
世界各地的采矿活动导致土壤养分流失,对作物和环境健康构成风险。基于16S rRNA测序和进一步的统计分析,我们在中国沛县市的煤炭基地调查了采后复垦活动对土壤理化性质和微生物群落的影响。结果表明,开垦土壤和参考土壤的土壤微生物相对丰度存在显著差异。无论开垦年龄如何,变形杆菌是所有七个矿场中最丰富的门,而不同矿场在其他层面的微生物群落结构存在相当大的差异。值得注意的是,变形菌门的γ-变形菌在大多数地方都有相对较高的丰度。此外,Kendall的tau-b相关热图显示,潜在的有毒元素和其他物理化学性质在微生物群落组成中起着至关重要的作用。
