Abstract: Forty-eight soil profiles were sampled from different ecological and pedogeochemical areas of China and their available selenium （Av-Se） contents were determined. Results showed that the content of Av-Se in the profiles of soils in China ranged within 2.49-18.10 μg kg--1 ) with a mean value of 10.01 μg kg--1，and was in the sequence of Ferralisols ＞ Luvisols ＞ Isohumisols ＞ Aridisols. The correlation analysis between Av-Se and the soil physical-chemical properties revealed that the correlations between Av-Se and O.M., CEC, Fe2O3,Al2O3, ignition loss, Co and Zn were positive at a highly significant level, but those between Av-Se and pH,base saturation, CaO, Ba and Sr were all negative at a highly significant level. The reason of some diseases related to the Se deficiency might be the leaching loss of selenium in some soils.
