| 摘 要： | 研究了兰定高速和兰州某物流园区汽车尾气对土壤中总铅及有效态铅含量的影响，研究物流基地、高速公路边和对照区土壤20cm和80cm深度中总铅含量及有效态含量，T检验比较不同区域、不同土壤层中有效态含量差别．结果证明：物流基地和高速公路边50m以内土壤总铅的含量明显高于对照．区域．T检验结果表明物流基地、高速公路边和对照区总铅含量有显著差异，物流园土壤20cm和80cm深度中总铅含量平均值为212．6mg·kg-1、148．4m4g·kg-1，明显高于兰定高速土壤总铅55．2mg·kg-1、46．9mg·kg-1的含量，3个区域有效态铅含量无显著差异．车速低、车流量大，则土壤总铅含量明显增加．

| Abstract: | Based on the study of lead content and available lead content in the soil of logistic bases and by the highways,it was found that the lead content in the soil of logistic bases and by the highways was significantly higher than the control area.T test results show that the lead content in the soil of studied areas is conspicalously different from the control area.However,the available lead content was not obviously different.Low speed and heavy traffic were major factors for the rise of lead content in the soil. |
