Abstract

The copper (Cu) content in 205 soil samples (0–20 cm) of Tibet, covering 5 soil classes, were analyzed. The results showed as follows: (1) the average content of Cu was 19.6 mg kg-1 (CV=49. 28%); (2) the content of Cu in Tibetan soils was lower than the average level of China; (3) the content of Cu gradually decreased from the southeast to the northwest which was consistent with the direction of changes in the zonal successions of soil in Tibet; (4) Cu contents in Tibetan soils varied with soil properties, particularly soil parent materials that Cu contents were remarkably enriched in soils derived from shale materials.
