摘    要:选择公路附近连片种植芋艿的路段,按距离路基远近不同布设土壤采样点15个,其中距离路基50m以外采样点9个、50m以内采样点6个,在室内试验的基础上,对路旁土壤重金属Pb、Cd、Hg、Cu、Zn、Cu的空间分布特征与污染状况进行了研究。结果表明,公路两侧50m范围内的土壤Cd、As、Hg、Cr、Cu、Pb平均含量比50m范围外高262.7%、47.8%、305.4%、64.7%、60.2%和158.9%。且距离公路越近土壤受到污染越明显,距离公路50m以外各监测点综合污染指数在0.180~0.367范围内,属清洁水平,适合无公害芋艿的生产;而距离公路50m以内的各监测点综合污染指数在0.492—0.736范围内,33.3%土壤的重金属污染达警戒水平(2级),不适合无公害芋艿的生产。

Abstract:In chosen the taro's cultivating on roadsides 15 soil samples are set up according to different roadbed distance,and 9 is 50 m outside,6 is within 50 m.On the basis of interior experiments,the space distribution characteristic and pollution condition of soil heavy metal(Pb,Cd,Hg,Cu,Zn,Cr)are studied.The result shows that the soil's average content of Cd,As,Hg,Cr,Cu and Pb within 50 m on roadsides is 262.7%,47.8%,305.4%,64.7%,60.2% and 158.9%,which is higher than 50 m outside.And the closer the soil near the...
