多元统计制图在土壤重金属分布格局解析中的应用

Application of Multivariate Mapping in the Distribution Pattern Analysis of Heavy Metal

以江苏省农用地土壤表层和底层土壤重金属含量数据为基础,运用地统计学方法对重金属主成分得分进行空间制图,通过制图来解析土壤重金属空间分布格局。

Based on the data of heavy metal contents in surface layer and bottom layer in agricultural land of Jiangsu Province,the spatial mapping was made on the scores of principal components of heavy metals by using geo-statistics method.The spatial distribution patterns of heavy metals in soil were revealed through mapping.
