| 摘 要： | 研究了延龙公路两侧旱田土壤中铅的分布规律.结果表明,在公路东侧距边沿100m左右污染最严重,在38.0m附近未污染,160.0m以外污染较轻,数学模型解析得到土壤铅含量在110.0m处达到最高峰;在公路西侧距边沿9.0 m、100.0m左右铅污染最严重,60.0 m附近未污染,在200.0 m以外污染逐渐减轻,数学模型解析得到土壤铅含量在4.2m处达到最高峰,在121.0m有1次高峰.

| Abstract: | In this paper the regularities of lead distribution in dry land soil beside Road Yanji-Longjing was studied,the results showed that the most serious lead pollution of east dry land soil was about 100m from the road,there was no pollution about 38m from the road,and there was less pollution beyond 160m.Through analyzing the mathematical model,the peak of lead content was about 110m.The most serious lead pollution of west dry land soil was about 9m and 100m,there was no pollution about 60m from the road,and there was less pollution beyond 200m.Through analyzing the mathematical model,the peak of lead content was about 4.2m,and the secondary peak was about 121.0m. |
