Difference

monthly
temperature
(a)
and
precipitation (b) in 2010 in the overgrazing areas of Northwest China
part of Gansu Province. The obvious conversion from grassland into barren land
will mainly occur in southern and central part of Inner Mongolia and Shanxi
Province, southern part of Ningxia Province, and southeast part of Gansu Province,
accounting for 42 % of the total number of converted grids. There will be nine
grids converting from grassland into urban land, accounting for about 10 % of the
total number of converted grids. In summary, the grassland in overgrazing areas of
Northwest China will be mainly converted into barren land and croplands.
5.3.2.2 Result of the Control Test
This study first simulates the temperature and precipitation in 2010 with WRF
model, then validates the correction of simulation, and the results indicate that
WRF model can simulate the temporal change of temperature very well
(Figs.
5.11
a and
5.12
a). According to the monthly temperature change in the entire
study area, the simulated temperature is roughly consistent with the observed value
in the spring and winter, and the difference between them ranges from 0 to 0.5 C
