摘要：
Potential soil loss rate by wind and water erosion in Jodhpur region has been assessed through Revised Wind Erosion Equation (RWEQ) and Revised Universal Soil Loss Equation (RUSLE) approach, respectively. In RWEQ approach, daily wind speed data of Jodhpur region were used to compute average wind factor at fortnight interval. Erodible fraction and soil crust factor of RWEQ was mapped using available soil series data. Soil loss through wind erosion was also assessed through field experiments. In case of RUSLE approach all component factors were calculated in GIS environment and potential soil loss rate map was prepared. On an average, maximum potential soil loss due to wind erosion has been approximated during second fortnight of May. Annual soil loss rate by water erosion has been found low (<12 t ha(-1)) in about 87% area of the region.
