The area of bare land changed into grassland was nearly five times (15,733.63 km\({}^{2}\)) that of grassland changed into bare land (3288.31 km\({}^{2}\)) during 2000-2010. In the second 11-year period, the ratio was again more than 2, at about 19,679.31 and 8805.19 km\({}^{2}\), respectively. From the spatial characteristics of the LUCC conversion process shown in Figure 3, it can be seen that the change of grassland shows spatial heterogeneity.
