不同尺度下耕地土壤cr含量的空间自相关性分析
DOI: 10.3724/SP.J.1145.2011.00393, PP. 393-397
Keywords: 土壤,重金属,空间自相关,不同尺度
Abstract:
以山东省禹城市耕地土壤重金属铬（cr）元素为例，采用moran’si统计量对县级和镇级两个不同取样尺度下cr含量的空间自相关关系、空间相关尺度和空间分布规律进行了对比研究.结果表明：1）随着研究尺度的增大，cr含量的变异系数增加，块基比（c0/sill）减小，空间结构性增强；2）两个尺度下cr含量moran’si指数都大于0，表明研究区内两个尺度下的cr含量都存在空间正自相关，且moran’si指数随着研究尺度的增加而增大；3）lisa聚类图表明，两个尺度下cr含量都存在空间聚集区和空间孤立区，其中“高―高”空间聚集和“低―高”空间孤立区域存在潜在cr污染风险.研究表明小尺度下能够观察到大尺度下观察不到的细微差别，研究可为土壤重金属环境质量评价和重金属污染防治提供重要参考.图4表2参23
