Fig. 6.7 Results of land use change simulation. a and b Show the simulation results of land use
in Southern Jiangsu in year 2010 under REG scenario and CES scenario, respectively; c and
d show the simulation results of land use in Southern Jiangsu in year 2050 under REG scenario
and CES scenario, respectively
There will also be some expansion of built-up land in small-medium cities, which
puts great pressure on the surrounding cultivated land and forest. Under CES sce-
narios, the speed of economic development will be restrained to some degree, and
land use intensity will be further improved and the consumption of land resources
due to economic development will also be restrained. Although there will be some
expansion of built-up land around the main urban areas of Nanjing, Zhenjiang,
Suzhou, Wuxi, and Changzhou, the expansion degree is much limited compared to
that under REG scenario. The area of cultivated land and forest will decrease
slightly due to built-up land expansion, but the decreased area has been under
