Research on Spatial-Temporal Variations of Cultivated Land in China Based on GlobeLand30

The period from 2010 to 2020 is a of rapid economic development in China, with the increasing population and urbanization level reaching 63.89%. Cultivated land plays an extremely important role China’s food security. In order grasp spatial temporal distribution change cultivated use China time, based on GlobeLand30 data 2020, this study studied characteristics total resources, utilization degree, dynamic degree rate, center direction by using GIS technology, reclamation index, rate model, shift model standard deviation ellipse model. results show that: ?The area has changed greatly during 2010–2020, largest increase Inner Mongolia Xinjiang, while decrease Shandong, Jiangsu, Hebei, Guangdong, Henan Zhejiang; ?The areas highest are mainly concentrated Henan, Anhui other provinces east, Qinghai, Tibet Xinjiang have lowest utilization; ?The regions index Mongolia, Liaoning, Shanghai, Zhejiang Guangdong shows obvious negative changes; ?The migration gravity trend “moving westward northward”, roughly presents overall northeast-southwest direction. This can effectively reveal variation at provincial GlobeLand30, provide scientific reference for further rational development, protection resources China.
