摘要

通过详细的调查分析，研究了浙江省优势农产区表层土壤重金属分异特征及其现状，并探讨了各种影响因素。904个代表性样品的分析结果表明，除As和Hg以外，Cd、Cr、Pb、Zn、Cu及Ni的含量均高于浙江省第2次土壤普查得到的表层土壤重金属含量；与杭嘉湖平原、浙江省、中国及世界土壤背景值的对比发现，研究区土壤大部分重金属元素的含量明显偏高，根据国家二级标准限值得出的单项评价结果表明，Cd和Ni的超标指数较高，分别达到lO．72％和9．7％。Hg、Pb、Cu和Cr次之，分别为6．80％，5，35％，3．43％和3．03％，Zn和As较小，分别为1．80％和1．04％。此外．通过对不同的土地利用类型、不同母质及土壤类型土壤中重金属含量的方差分析，研究了这些因子对浙江省农业土壤重金属含量的影响程度及其原因。

Abstract

Heavy metal contents in top soils in agricultural soils of Zhejiang province and their differential characteristics and effecting factors were studied in the presented paper through field soil investigation.Averages of total Cd

Cu and Ni

except As and Hg

in the 904 selected soil samples were higher than the contents in top soils based on the second general survey of soil of Zhejiang province.The result showed that most of the heavy metal contents were enhanced excessively contrasted with the background values of Hangjiahu plain

Zhejiang province

China and the whole world.It was found that heavy metal contents exceed the threshold levels according to the second grade of standards for soil environmental quality of China(GB15618-1995)

the index of exceed the provided standard of Cd

As and Zn were 10.72%

9.70%

6.80%

5.35%

3.43%

3.03%

1.80%and 1.04%

respectively.Moreover

land use

parent material and soil type were analyzed by the variance analysis to study the influence to heavy metal concentrations in agricultural soils by these effective factors.
