Abstract:This study is aimed to study the spatial distribution of PSDs and erodibility factor K of soils in the inland arid area as well as their relations with soil salinity. In total 66 surface soil samples were collected from the Ebinur Lake Wetland in Xinjiang Uygur Autonomous Region of China in May of 2015, PSDs, salinities and organic carbon contents of soil samples were measured, and the fractal dimension Ds and erodibility factor K were calculated. The results showed that 59.09% of soil samples was salinized with a mean salt content of 131.59 g/kg, indicating salinization is common and serious in the study area. Soil particles were mainly silts and sands, clays increased but sands decreased with the increase of salinization degree. Soil fractal dimension D was between 2.14 ~ 2.60 with a mean value of 2.45. In addition, with the increase of salinization degree, D and K gradually increased, the maximum K was 0.093. The correlation between K and soil salinity was extremely significant (r= 0.596**), thus, to a certain extent, it could be concluded that the higher soil salinity, the higher K value and the more likely to be eroded.
