摘要
我们对干线公路两侧土壤中铅的分布规律进行了研究，得出了公路两侧土壤中铅的含量与离公路边沿的距离符合高斯衰减分布模型。通过比较在正常速度行驶和怠速行驶路段的模型参数，对公路两侧土壤中铅含量的影响因素进行了讨论。
In this paper the distribution of lead in soil along highway was studied,and a Gauss decay regression model was worked out to describe the relation between the lead concentration in soil along highway and the sampling distance away from the edges of highway.By the comparison of the model parameters in normal speed section and idling speed section of highway,some factors,which do affect the lead concentration in soil along highway,were discussed.
