摘      要：Inner Mongolia is the important ecological barrier zone in northern China,which plays an important role in the prevention and control of wind in the regional *** on the Revised Wind Erosion Equation(RWEQ)model and the cost-recovery method,this study simulated the wind erosion prevention service(WEPS)in Inner Mongolia in 2010 and 2015,investigated the spatial pattern of material and monetary value of WEPS,and analyzed the differences among various cities and various *** results indicated that the total WEPS of Inner Mongolia was estimated to be 73.87×10^(8) t in 2015,which was 4.61×10^(8) t less than in 2010,while the monetary value of WEPS was calculated to be 738.66×10^(8) yuan in 2015,which was 46.16×10^(8) yuan less than in *** all the leagues and cities,Xilin Gol League supported the highest WEPS,reaching 18.65×10^(8) t in 2015,while Wuhai provided the *** WEPS of Hulunbeier increased the most,by 4.37×10^(8) t from 2010 to *** WEPS in the grassland ecosystem was the highest among the different ecosystems,accounting for more than55%of the total WEPS in Inner Mongolia,but it was reduced by 1.05×10^(8) t during the same *** WEPS in the forest ecosystem increased the most,reaching 0.19×10^(8) *** study found that the implementation of projects such as returning farmland to forests and grasses and sand control effectively increased the WEPS by increasing the forest ***,unsuitable land use increased the desertification of ecosystems which resulted in a reduction of WEPS in Inner Mongolia.
