中文摘要	通过野外调查与室内实验分析研究了干旱区典型的矿业城市-金昌市郊农田土壤中重金属Zn、Ni、Cu、Pb、Cd五种重金属的EDTA提取态含量情况,并利用surfer对数据进行了空间插值分析.结果表明,金昌市郊农田土壤中这五种元素的EDTA提取态中,Cu的平均提取含量最高,Ni、Zn、Pb的提取态含量相对比较低,Cd的最低.相关性分析的结果显示,这五种重金属的EDTA提取态含量两两之间均呈显著正相关关系;EDTA提取态含量与其全量之间也均呈正相关关系,但只有Cd和Cu两种元素的相关性达到了显著性水平.空间分析表明,这五种重金属EDTA提取态的含量均在自家咀和马家崖子附近存在高值区.
英文摘要	EDTA extractable quantities of Zn,Ni,Cu,Pb,Cd in the soils from the suburb of Jinchang city-a typical arid region of the mining city were studied through the investigation in the field and the analysis in the laboratory. The data of EDTA extractable Zn,Ni,Cu,Pb,Cd contents in the soils were analysed applying the Kriging interpolation method of surfer. The findings indicated that the average contents of Cu extracted by EDTA were higher than those of other four metals, and EDTA extractable fractions of Cd were the least contents. The correlation analysis indicated that there were markedly significant positive correlations between EDTA extractable fractions of Zn, Ni, Cu, Pb and Cd in soils. There existed positive correlations between total contents of Zn, Ni, Cu, Pb, Cd,and their EDTA extractable fractions, respectively; but only for Cd and Cu, the correlations reached the significant level. Spatial analysis indicated there were relatively large contents of EDTA extractable fractions of all five metals near Baijiazui and Majiaaizi.
