| 摘 要： | Based on China homogenized land surface air temperature and the National Centers for Environmental Prediction/Department of Energy (NCEP/DOE) Atmospheric Model Intercomparison Project (AMIP)-Ⅱ Reanalysis data (R-2), the main contributors to surface air temperature increase in Southeast China were investigated by comparing trends of urban and rural temperature series, as well as observed and R-2 data, covering two periods of 1954-2005 and 1979-2005. Results from urban-rural comparison indicate that urban heat island (UHI) effects on regional annual and autumn minimum temperature increases account for 10.5% and 12.0% since 1954, but with smaller warming attribution of 6.2% and 10.6% since 1979. The results by comparing observations with R-2 surface temperature data suggest that land use change accounts for 32.9% and 28.8% in regional annual and autumn minimum temperature increases since 1979. Accordingly, the influence of land use change on regional temperature increase in Southeast China is much more noticeable during the last 30 years. However, it indicates that UHI effect, overwhelmed by the warming change of background climate, does not play a significant role in regional warming over Southeast China during the last 50 years.

| Abstract: | Based on China homogenized land surface air temperature and the National Centers for Environmental Prediction/Department of
Energy (NCEP/DOE) Atmospheric Model Intercomparison Project (AMIP)-II Reanalysis data (R-2), the main contributors to surface
air temperature increase in Southeast China were investigated by comparing trends of urban and rural temperature series, as
well as observed and R-2 data, covering two periods of 1954–2005 and 1979–2005. Results from urban-rural comparison indicate
that urban heat island (UHI) effects on regional annual and autumn minimum temperature increases account for 10.5% and 12.0%
since 1954, but with smaller warming attribution of 6.2% and 10.6% since 1979. The results by comparing observations with
R-2 surface temperature data suggest that land use change accounts for 32.9% and 28.8% in regional annual and autumn minimum
temperature increases since 1979. Accordingly, the influence of land use change on regional temperature increase in Southeast
China is much more noticeable during the last 30 years. However, it indicates that UHI effect, overwhelmed by the warming
change of background climate, does not play a significant role in regional warming over Southeast China during the last 50
years. |
