Fig. 3.4 Land use change trends of China under CES scenario during 1990-2095; a Land use
change trends of cultivated land, forest land, grassland and built-up land; b trends of managed and
unmanaged forest land; c trends of grazed and other grassland (1,000 km 2 )
grassland has been in a downward trend during 1990-2065, and then become
stable after 2065, while the explored grassland increases obviously. Therefore,
CES scenario has positive effect on the protection of environment, and it is con-
sistent with the model of sustainable development and low-carbon economic
development. Apparently, urbanization still plays an irreplaceable positive role in
the process of social-economic development, and the built-up area also has an
increasing trend under CES scenario.
