摘　　要：针对环境科学研究中的渗流力学问题,从环境科学理论和渗流力学理论出发,探讨了挥发性有机污染物在土壤中的迁移机制和规律、地下水多组分反应溶质的迁移模型和规律;分析了垃圾填埋场气体迁移和二次污染问题。在此基础上,提出了挥发性有机物的迁移过程及控制机制的不确定性的两个方面和多组分水化学模型与水动力迁移模型的耦合模型建立的必要性。文中分析对环境科学与渗流力学交叉研究问题的深层次认识具有重要的理论价值和实际意义。In this paper, in the light of the percolating flow mechanics problems in the field of environmental science research , the transport mechanism and law of the volatile organic pollutants in the soils and the transport model and law of the underground water multi-component reacting solute are discussed, and the gas transport and the second pollution problems in the solid waste landfill are analyzed~ Based on the research given above, the transport process and two aspects of the control mechanisms uncertainty for the volatile organic matter and the necessity to establish the coupling model of multi-component water chemistry model and waterdynamic transport model are pointed out. The result is of great theoretical importance and practical significance to the further understanding of the overlapping research problems in environmental science and percolating flow mechanics.
