摘　　要：建立了地下水环境中甲基叔丁基醚(MTBE)运移过程的变系数动力学模型,并对模型进行了验证和参数灵敏度分析。模拟结果表明,地下水流速和阻滞系数对于MTBE的运移过程影响最为显著,而水动力弥散系数的影响较小,忽略其变化不会对预测地下水环境中污染物运移的环境动力学行为造成太大误差。由此得到的结论可定量研究MTBE在地下水环境中的对流-扩散特征,还可为MTBE污染地下水的预测预报、修复治理等研究提供科学依据。For describing the transport of organic compounds in porous medium, the dynamics model of methyl tert-butyl ether （MTBE） in groundwater was developed. Furthermore, the discussion about model validity and parameters sensitivities was also conducted in this paper. The simulative results indicate that the velocity of groundwater and the retardation coefficient are the key factors influencing the transport of MTBE in subsurface, whereas the dispersive coefficient has no obvious effect on it. The model and results will be reliable basis for the forecast and the remediation of groundwater contaminated by MTBE.
