中文摘要：
在GIS支持下,结合地统计学软件Surfer对广东省261个土壤剖面的锌环境背景值进行空间变异分析,结果表明,锌的分布异质性较强,淋溶层、淀积层、母质层3层都显示出中等的空间相关性,空间变异模式趋于一致;背景浓度高的土壤样品通常位于断裂带、盆地和三角洲地区,并与区域盆地的空间分布对应;锌背景值从淋溶层到母质层呈明显的增长趋势。
英文摘要：
Based on GIS with Geo-statistics analyst software(Surfer 8.0),a total of 261 soil profiles were used to investigate the vertical variation and spatial distribution of Zn environmental backgroud values in Guangdong province.The distribution of Zn was heterogeneous.The spatial distribution of Zn presented similar patterns that the relatively high concentrations of Zn mainly located in fault,basin and delta areas,indicating that distribution of Zn in the soil was according with regional basin.Moreover,mean concentration of Zn had an increasing tendency from leached to mother material horizon.
