| 摘 要： | 以上海化学工业区表层土壤元素为研究对象,采用相关分析方法研究了20种土壤元素的富集和迁移转化规律。回归分析表明,元素Ni含量与Ca、Cd、Cu和Fe的含量密切相关;通过聚类分析,可将20种元素分为三大类;因子分析得到的前五个主因子代表了土壤元素中72.0%的信息量。

| Abstract: | The topsoil samples in Shanghai Chemical Industrial Park were investigated systematically. The correlation analysis method was used to study the regularities of accumulating, migrating and conversing of the selected 20 elements. The regression analysis showed that the content of Ni was related to Ca, Cd, Cu and Fe closely. Based on the cluster analysis, the 20 elements can be divided into three types. The five principal factors indicated 72.0% information selected in factors analysis. |
