[ Objective] The research aimed to determine the organic matter content in soil from different areas in Qinghai. [ Method] The organic matter content in soil and turf from 10 areas in Qinghai Province was determined by external heating method and potassium dichromate volumetric method. [ Result] The results showed that the organic matter content in soil from Datong, Menyuan, Gonghe and Tianjun was 36.79～58.64 g/kg,and that from Yushu, Qilian, Gangcha, Xinghai, Huangyuan and Hualong was 155.90～287.00 g/kg. Thereinto, the organic matter content in soil from Qilian was the highest, was 287.00 g/kg. [ Conclusion] The determination method was credibility and the data was nicety, can provide the scientific basis for general investigation and exploiting turf resources in Qinghai Province.
