The Process-Mode-Driving Force of Cropland Expansion in Arid Regions of China Based on the Land Use Remote Sensing Monitoring Data

The center of gravity China’s new cropland has shifted from Northeast China to the Xinjiang oasis areas where ecological environment is relatively fragile. However, we currently face a lack comprehensive review expansion in Xinjiang, which importantly associated with sustainable use cropland, social stability and security. In this study, land remote sensing monitoring data 1990, 2000, 2010 2018 were used comprehensively analyze process characteristics, different modes driving mechanisms as well its spatial heterogeneity at area level. results revealed that continued expand 5803 thousand hectares 1990 8939 experienced three stages expansion: steady expansion, rapid slow expansion. showed characteristic shifting South.
