- Abstract:
-
In order to study the effect of land use/vegetation cover change(LUCC)on climate change in the Mu Us Desert, we used observation minus reanalysis(OMR)and matrix of dynamic change of land use to analyze the impact of LUCC on climate change before and after desertification reversal in Mu Us Desert and assessed how LUCC drove regional climate change in the study region. The results showed significant differences in precipitation and temperature changes before and after desertification reversal. However, the changes in precipitation and temperature were similar between sandy and loess sites, indicating that the underlying surface situation had not significantly influenced the response of precipitation and temperature. Change in precipitation was mainly regulated by evapotranspiration. The LUCC resulted in the changes in evapotranspiration, reflectivity, net radiation, etc., ultimately led to change in temperature. The result showed that effect of LUCC on temperature was greater than the effect on precipitation. Compared with the average temperature, the maximum and minimum temperature were more sensitive in responding to LUCC. These results suggested that the changes of precipitation and temperature were mainly caused by vegetation restoration regardless of substance composition of underlying surface.
