摘　　要：铁路运输在推动路域经济发展的同时,也会对路域生态环境带来某些不良影响。水果品质与种植园土壤元素含量有直接关系,研究铁路周边脐橙种植园土壤元素含量对于农产品安全以及铁路周边生态环境建设都具有十分重要的意义。脐橙是一种人们十分喜欢的优质水果,在铁路周边尤其是四川省、重庆市、湖北省、江西省、贵州省等南方地区的铁路周边的栽种面积很大。应用原子吸收光谱法检测了四川省金堂县境内1997年建成的成达铁路沿线脐橙种植园土壤与对照土壤中Pb,Cd,Mn,Cu,Zn等多种元素的含量。结果表明,铁路周边脐橙种植园土壤中重金属元素Pb和中量元素Mn比对照土壤增加明显,但重金属元素Cd与微量元素Cu和Zn在铁路周边脐橙种植园土壤与对照土壤之间差别并不明显。Railway transportation has boosted the economy of railway road area,meanwhile it brings some undesirable impacts on the environment of the railway road area.The quality of the fruits is directly related with the elements of the soil,so understanding the element contents of soil in navel oranges garden in the vicinity of railway is meaningful to the security of agriculture products and ecological conditions in the areas surrounding the railways.As a favorite fruit,navel orange is widely planted around the railway in the south China,especially in Sichuan,Chongqing,Hubei,Jiangxi and Guizhou.The present paper studied the contents of Pb,Cd,Mn,Cu,Zn etc in the soil planting navel orange in the vicinity of Chengdu-Dazhou railway by AAS.The railway was built in 1997 and the research area was sited in Jintang county,Sichuan.The results showed that the contents of Pb and Mn in soil planting navel orange were significantly higher than those in the control soil,but the contents of Cd,Cu and Zn showed no significant difference.
