土壤环境的生物地球化学过程、质量演变和风险管理研究展望

PROSPECTS OF THE RESEARCH ON BIOGEOCHEMICAL PROCESSES,QUALITY EVOLVEMENT AND RISK MANAGEMENT OF SOIL ENVIRONMENT

结合国内外研究现状和发展趋势分析,提出开展土壤环境的生物地球化学过程、质量演变和风险管理研究。认为将土壤环境划分为内部、界面和外部三部分,有助于认识土壤环境中污染物的交换与循环规律及其相互影响。强调了开展土壤环境的物理-化学-生物学-地学交叉、综合研究的必要性,并从土壤颗粒表面-溶液、土壤-生物、土壤-植物、土壤-大气、土壤-水体等土壤环境子系统探讨了科学问题,展望了未来研究方向,旨在促进不同尺度土壤环境的质量变化规律与修复调控研究。

Based on analysis of the status quo and developmental trend of the study on soil environment at home and abroad, the author suggests in this paper initiation of research on biogeochemical processes, quality evolvement and risk management of soil environment. The author holds that the assumption of soil environment consisting of three parts, internal, interfacial and external ones, is helpful for better understanding of processes, cycling and interaction of pollutants in the soil environment. The author also emphasizes necessity of developing integrated interdisciplinary （physio-chem-bio-geoscience） research of soil environment, and discusses potential subjects and prospects of the research from the aspects of the subsystems of soil particle surface-liquid, soil-microorganisms, soil-plant, soil-air, and soil-water in the environment, aiming at promoting the study on evolution rules, regulation and remediation of soil environmental quality on different scales.
