中文摘要：

在武汉市东湖高新技术开发区采集土壤样本136个,测定Cd、Cu、Ni、Pb、Zn和Cr的含量,发现Cd平均含量超过湖北省背景值,并且在研究区大片区域都超过了国家环境质量二级标准.Cu平均含量接近背景值,而其它元素均低于背景值,但部分区域仍有富集.地统计分析显示6种重金属自相关性较弱,重金属含量高值主要分布于研究区中部以及西北部.从空间分布看,Cd、Cu、Ni和Cr的富集可能主要来源于区内企业生产排放.Pb和Zn含量主要由自然因素决定,外界基本没有输入,部分区域富集的Pb可能由交通因素造成,Zn的局部累积可能来自于农业措施.综合污染指数显示区内整体存在污染,需要采取必要的措施进行治理.

英文摘要：

136 topsoil samples were collected from Wuhan Donghu High-tech development Park, and the concentrations of Cd, Cu, Ni, Pb, Zn and Cr were determined. Results showed that average content of Cd exceeded provincial background value, and also exceeded the second-level of the National Environmental Quality Standards of China in most part of the study area. The average concentration of Cu approximated its provincial background value. Although the rest of soil heavy metals were lower than background value, accumulations were observed in a fraction of study area. The results of geostatistical analysis indicated that the auto-correlations of all of the six heavy metals were weak and high values were mainly found in the center and northwest of the study area. According to the spatial distributions of heavy metals, the accumulations of Cd, Cu, Ni and Cr were mainly derived from emissions of manufacture in this area. The contents of Pb and Zn were determined by natural process, which means there was nearly no import from outside. The relatively high value of Pb could be the result of transportation here. However, the excessive Zn possibly came from some agricultural measures. Nemero Synthesis Index specifically indicated that the study area was polluted. As a result Great attention should be paid to the pollution situation of the park with necessary control measures.
