[Objective] In order to solve the problems about transferring the existing data of soil texture between different standards, the soil census data based on Chinese soil particle size classification standard were applied to revise the wind erosion equstion model(RWEQ).[Methods] This thesis tried to use the lognormal distributed model to convert the soil particle size and discussed the applicability and feasibility of lognormal distributed model in describing the character of soil particle distribution in Inner Mongolia Autonomous Region, Jilin Province, and Shaanxi Province, etc.[Results] The research result showed that lognormal distributed model can well simulate the content of soil particles. The regions with high soil crust factor and soil erodible fraction are those windy desert region in Northern China, followed by the regions with frigid calcic soils.[Conclusion] Soil crust factor can either decrease or increase erodible fraction in different cases. Determining rainfall amount that soil surface can crust and subsequently minimize the soil wind erodibility in different climate conditions should be the key to the future.
