Abstract

Based on GIS with Geo-statistics analyst software (Surfer 8.0), total of 261 soil profiles were reported to investigate the Cu spatial distribution and vertical variation in Guangdong province. Cu spatial distribution presented similar patterns that high Cu concentration mainly located in fault, basin, and delta areas, indicating that soil Cu distribution was dependent on regional basin. Moreover, from A- to C-horizon Cu mean concentrations had an increasing tendency. Regional extensive distribution of granite and the fault mainly decided the spatial distribution of Cu concentration. Soil organic matter and clay content also, to a certain extent, affect the spatial distribution of Cu concentration.KeywordscomponentGeo-statisticsspatial distributionCu Concentration
