摘要

对贵州省六盘水市某铅锌冶炼厂废弃地复垦整理区土壤中重金属Cu，Zn，Pb，Ni，Cd，Cr，Hg，As以及土壤部分理化性质进行了测定和分析，对土壤重金属污染状况进行了评价。结果表明：废弃地上堆放的铅锌冶炼矿渣中除Cu，Cr，Hg的含量较低、污染指数小于1之外，Zn，Pb，Ni，Cd，As的含量很高，其单项污染指数分别为2．95，45．14，1．00，10．67，50．41，综合污染指数高达36．98，属于剧烈污染源。项目区土壤综合污染指数在0．77～1．99之间；综合污染指数小于1的未受重金属污染的土壤占总样品数的50．00％，而综合污染指数〉1．00但没有超过2．00的样品数占总样品数的50．00％，说明项目区仅有部分土壤遭受重金属的轻度污染。采用适当的复垦整理、改良技术和合理的利用方式，可以促使该废弃地恢复农业生产能力。

Abstract

The content of soil heavy metals

As and part physical and chemical properties of the soil were determined and analyzed in the area in Liupanshui city of Guizhou province

then the appraisal for heavy metals pollution was made.The result is showed as follows: the content of Cu

Hg in the mireral slag is low

with their pollution indices lower than 1

while that of Zn

As is much higher

which single pollution index is 2.95

45.14

1.00

10.67

50.41 respectively

and the comperhensive pollution index is as high as 36.98

attributed to the string pollution resource.At the same time

the comprehensive pollution index for the soil is between 0.77 and 1.99

among which the samples with the index lower than 1 account for 50%

while proportion with the index between 1 and 2 is 50%.That result indicates that only part soil is polluted by heavy metal in low grade in the area.Therefore

proper technology of reclamation and improvement and utilizition way should be taken to ensure the soil to restore its ability to producting in argriculture in this area.
