为评价庐南矿山土壤修复工程修复效果,选取该矿区典型土壤退化区域大岭、小岭及矾山排土场为研究对象,对各区域修复前、修复中以及修复后不同状态的表层土壤进行理化性质、重金属总量变化特征的研究,同时分析了修复中与修复后不同时期表层土壤微生物群落的物种组成及多样性变化.结果表明:庐南矿区修复工程抑制了表层土壤酸化并使其达到自然背景值,提升土壤养分含量,并有效降低了重金属的环境风险.此外,修复后的土壤微生物群落多样性提高,其结构转变为以促进碳循环、植物生长和营养元素循环为主导的功能性群落,这对于维持和促进庐南矿区土壤退化区域的长期生态恢复具有重要意义.基于表层土壤修复情况,庐南矿区修复总体取得了良好的效果,为类似矿区的生态修复提供了宝贵的经验.
Preliminary Study on the Promotion of Ecological Restoration by Microbial Remediation Techniques in a Mining Area of Southern Lujiang,Anhui
In order to evaluate the remediation effect of soil remediation project in Lunan mining area,selected the typical soil degradation areas of Daling,Xiaoling and Fanshan dumps in the mining area as the re-search objects,and studied the physical and chemical properties and total heavy metal content of surface soil in different states before,during and after remediation.At the same time,the species composition and diversity of surface soil microbial communities in different periods during and after remediation are analyzed.The re-sults showed that the remediation project in mining area of southern Lujiang inhibited the acidification of sur-face soil and made it reach the natural background value,improved the soil nutrient content,and effectively reduced the environmental risk of heavy metals.In addition,the soil microbial community after remediation showed higher diversity,and its structure is transformed into a functional community dominated by promoting carbon cycle,plant growth and nutrient element cycle,which is of great significance for maintaining and pro-moting the long-term ecological restoration of soil degradation area in Lunan mining area.In general,from the perspective of surface soil restoration,the restoration of mining area of southern Lujiang has achieved good re-sults,which provides valuable experience for the ecological restoration of similar mining areas.
