Abstract:: Sampling and testing were conducted on the sandy soil erosion intense and its inhibiting factors in the 3 408km² of south Kurbantonggut desert,and semi-variograms function analysis was made afterwards on the data obtained by the application of geo-statistics.Results showed the data of the sandy soil erosion intense and its inhibiting factors for actual measurement submitted to the normal distribution.The variance curves of the soil water content and the sandy soil erosion displayed a spherical model,while the curve of the vegetation coverage exhibits an exponential in the area.Analysis of monitoring data from 2009 indicated that the vegetation coverage,soil water contents,and sandy soil erosion varied spatially in this area.The sandy soil erosion intense decreased (or increased) in the spatial scale,while that the vegetation coverage and the soil water contents increased (or decreased),the sandy soil erosion intense highly depended on the vegetation coverage and the soil water contents.Therefore,the vegetation coverage and the soil water contents are the key factors inhibiting sandy soil erosion intense,they are also the critical factors preserving stability of south Kurbantonggut desert.
