摘　　要：随着土壤利用模式变化及矿产资源不断开发,土壤微生物活性降低及矿山土壤生态恶化已成为阻碍社会生产效率提高的主要因素之一.由于国家和社会逐渐重视土地高质量发展及微生物生态修复工程,本文综述了土壤微生物对碳、磷、氮和其它非金属污染物的代谢模式,并且基于土壤生态系统特性,讨论了微生物驱动的物质循环影响因素(pH、营养条件、重金属等土壤因子).阐述了微生物多样性和根际环境的形成在矿山生态环境修复初期所起的重要作用,并通过土壤环境的外场作用机制分析,揭露了电、磁、紫外等外场的控制将有助于微生物群落及其功能的可控方向演变,对土壤污染物阻控和理化特性改善并推动实现退化土壤生态结构与功能的重塑具有重要意义.With the change of soil utilization patterns and the continuous exploitation of mineral resources,the decrease of soil microbial activity and the ecological deterioration of mineral soils have become one of the main factors that hinder the improvement of social productivity.As the country and society are gradually paying attention to high-quality land development and microbial ecological remediation projects,this paper reviews the metabolic patterns of carbon,phosphorus,nitrogen and other non-metallic pollutants by soil microorganisms,and discusses the microbially driven material cycling factors(pH,nutrient conditions,heavy metals and other soil factors)based on soil ecosystem characteristics.The importance of microbial diversity and the formation of the inter-root environment in the initial phase of mine ecosystem restoration is described,and through the analysis of the external field action mechanism of soil environment,revealing that the control of external fields such as electric,magnetic and ultraviolet will contribute to the controlled evolution of microbial communities and their functions,which is significant for the control of soil contaminants and improvement of physicochemical properties as well as promoting the remodeling of ecological structure and function of degraded soils.
