A straw checkerboard barrier of Ketu and Shadao in desertification combating areas around Qinghai Lake is selected to survey, take sample and analysis. Preliminary results show that in straw checkerboard barriers of Ketu the average particle size is 1.71(φ) in the depth of 0-30 cm, the average standard deviation is 0.68(φ), the average skewness is -0.12(φ), the Kurtosis is 1.18(φ). The average particle size is 1.74(φ) in the depth of 30-50cm, the average standard deviation is 0.85(φ), the average skewness is -0.06 (φ), the Kurtosis was 0.98 (qb). In straw checkerboard barriers of Shadao, the average particle size is 2.22(φ) in the depth of 0-30cm, the average standard deviation is 1.13(φ), the average skewness is -0.10(φ), the Kurtosis is 1.02 (φ). The average particle size is 2.22 (φ) in the depth of 30-50 cm, the average standard deviation is 1.08 (φ), the average skewness is -0.08(φ), average Kurtosis is 0.99(φ) which is moderate kurtosis.
