The soil erodibilities are compared and appraised for the majority of the soil types in Ningxia. The method published by D. W. Fryrear et al is adopted to calculate erodible fractions for the soils in Ningxia. The erodibilities of main soil types are compared and analyzed. Spatial distribution of soil erodibilities in the region can be perceived on the Map of Ningxia Soil Erodibility. The map is based on the digitized map of soil types of the all region by means of the geographical information system of Region Manager. Evaluation results show that erodible soils occupy a large portion of the total area of the region.(3) The third task is evaluation of effects of human activities for farming on soil erodibility. Tillage and cultivation can alter soil properties. The paper, based on the discussion on the characteristics of farmland suffering wind erosion in the region, analyzes the contents and intensities of farming disturbing surface soil. Emphasis is paid on the effect of farming on erodibilities of each type of soil.
