effect difference of three scenarios appears at the hottest month of the year (June,
July, and August). In colder months (January, February, November, and December),
the difference of warming effect under three scenarios is small.
Under different scenarios of urbanization, there are significant differences of
spatial patterns of impacts of land surface on temperature change (Fig.
6.20
). From
the differences of three scenarios, variation between centralized and decentralized
urban land expansion scenario is the biggest, while there are small differences
between centralized urban land expansion scenario and baseline scenario. Com-
pared to decentralized urban land expansion scenario, the spatial range of warming
effect is much stronger under centralized urban land expansion scenario, and the
magnitude of temperature difference was greater too. Compared to baseline sce-
nario, the spatial range of warming effect was a little stronger and more concen-
