This article adopts samples from farmland soil in Zhang Yi Zhan, Shenyang City, where is located in China’s northeastern industrial polluted area, assisted by systematic absorption test and soil column device and measuring system, to conduct in-depth study on the transfer rule of a persistent pollutant-organochlorine pesticide (OCP) BHC in soil, by which we could obtain the spatiotemporal variation process of pollutant concentration in unsaturated soil column under certain pollution transport condition. The experiment result indicates, that by comparing the leaching curves of each soil column filled with sample soil collected from various soil layers across the district, we could find that the transfer velocity of BHC in the vadose zone of soil column No. IV（60~80cm) was faster than that in No. I（0~20cm), No. II（20~40cm） and No. III（40~60cm）, while that in No. V （80~100cm）was the maximum. This was possibly due to its close to upper soil layer where high content of clay and organic matter exist, while the lower soil layer was nearly sandy with low content of organic matter. However, the proved research shows, that soil's absorptive capacity to BHC would grow with an increase of organic matter content, therefore, the soil column No. V had smaller absorptive capacity than No. IV, and much smaller than No. I, II and III, extending the transfer capacity of pollutant to a larger degree. Namely, once the water body polluted by OCP reached to the lower soil layer of vadose zone, its transfer velocity would accelerate, which could be potentially hazardous to ecological system and underground water. Thus to research on the transfer characteristics of BHC in each soil layer of vadose zone would be of great importance as it would provide theoretical basis for improvement and restoration of soil and underground water pollution.
