| Abstract: | Based on Geo-statistics analyst software(Surfer 8.0),259 soil profiles were used to investigate the spatial variation and vertical distribution of Cr in Guangdong province.The soil background levels of Cr in Guangdong were higher than the national background average level,but close to the world average level.It decreased gradually from northwest to southeast and showed weak growth trend from A to C layer. |
