摘　　要：通过盆栽试验,研究了土壤中的石油类污染物对高粱、玉米生长的影响,当土壤中石油烃含量小于1mg/kg时,石油烃对植物的生长有促进作用;当土壤中的石油烃含量较高时,对植物的生长有抑制作用。为石油污染土壤的风险评价以及修复等提供了理论依据。Pot experiments were carried out to study the effect of petroleum hydrocarbon pollutants in soil on growth of sorghum and corn. It was found out that the petroleum hydrocarbon would promote growth of plants when its content in the soil was lower than lmg/kg; while the petroleum hydrocarbon would restrain growth of the plants when its content was high. The research results provided the theoretic bases for risk evaluation of pollution of the soil by the petroleum hydrocarbon and reparation.
