Abstract:This research dealt with Se content and distribution of 16 soil types of Qinghai.The result showed that the content of Se was significant difference in different type of soil.It was highest in swamp soil 0 296mg/kg and the lowest in sub-alpine meadow soil 0 08mg/kg Se content of soil surface stratum was relatively high in the south foot of the Qilian mountain,the east of the Qinghai and the region from soil deposited belt to center of the Chaidamu basin 0 2mg/kg.In the west part of Haixi and Yusu,the region of Kuokuoxili and the almost whole area of Guolo,the Se content of soil surface stratum was low 0 1mg/kg.In general,the Qinghai province belongs to the region of low selenium,but the Se content of surface stratum was higher than that whole country in same type of soils.
Keywords:soil  total selenium  distribution
