Impact of Cropland Evolution on Soil Wind Erosion in Inner Mongolia of China

Understanding soil erosion responses to cropland expansion/shrinking plays a crucial role in regional agriculture sustainability development drylands. We selected Inner Mongolia, typical water resource constraints region with acute expansion, as the study area China. Spatial evolution and its impact on wind-driven were investigated help of field sampling data, remotely sensed retrieved revised wind model (RWEQ). Results showed that Mongolia presented an increased growth trend, net increase 15,542.9 km2 from 1990 2018. Cropland characteristics continuous eastern region, basically constant central declined western region. Most declines occurred after 2000 when Grain for Green project began, which means expansion happened 2000. The modulus expansion. reclamation forests grasslands contributed 5.0 million tons modulus, 80% was produced part conversion croplands grasslands/forests caused decrease approximately 2.7 tons, 62% east 25% west Considering shortage over-exploitation groundwater, we provide path based balance between ”resource-production-ecosystem” achieve ecologically sustainable drylands
