%X A new soil column-leaching test is applied to simulate the effects of natural precipitation on the petroleum's vertical migration in soil of the Longdong loess plateau region, considering different conditions of infiltration of water, intensity of petroleum pollution and column's length. The experimental results indicate that the depth of the petroleum contaminants'transport is limited by several factors of the intensity of petroleum pollutants, leaching volume and the depth of soil layer. The depth of the contaminant's maximum performance increases significantly with the increasing of petroleum pollutants contents and intensity, and the depths of the columns. A large number of contaminants mostly exist in soil within 0~10 cm.
