Most studies on bacterial transport in soils were carried out in columns under controlled conditions, and the results were various, reflecting the need of standardizing the method. Other methods were also used in conjunction with microscopy to examine the transport at pore scale. Mathematical models based on convection-dispersion equation were developed to simulate bacterial transport. Within specific limits, these models could simulate the major behaviors of bacterial transport. However, they neglected some parameters such as the growth and death of bacteria. The theoretical development, experimental size, scale exchange and modeling for predicting bacterial transport at field scale should be further studied.
大多数关于细菌在土壤中迁移的研究是在可控条件下的柱体中进行的，结果各不相同，这反映了对该方法进行标准化的必要性。其他方法也与显微镜结合使用，以研究孔隙尺度下的迁移情况。基于对流扩散方程开发了数学模型来模拟细菌迁移。在特定范围内，这些模型可以模拟细菌迁移的主要行为。然而，它们忽略了一些参数，如细菌的生长和死亡。对于预测田间尺度下细菌迁移的理论发展、实验规模、尺度转换和建模仍需进一步研究。
