| 英文摘要 | Based on the land surface temperature (lst), the land cover classification map, vegetation coverage, and surface evapotranspiration derived from eos-modis satellite data, and by the use of gis spatial analytic technique and multivariate statistical analysis method, the urban heat island (uhi) spatial distribution of the diurnal and seasonal variabilities and its driving forces are studied in beijing city and surrounding areas in 2001. the relationships among uhi distribution and landcover categories, topographic factor, vegetation greenness, and surface evapotranspiration are analyzed. the results indicate that: (i) the significant uhi occur in beijing city areas in the four seasons due to high heat capacity and multi-reflection of compression building, as well as with special topographic features of its three sides surrounded by mountains, especially in the summer. the uhi spatial distribution is corresponding with the urban geometry structure profile. the lst difference is approximately 4-6 degrees c between beijing city and suburb areas, comparatively is 8-10 degrees c between beijing city area and outer suburb area in northwestern regions. (ii) the uhi distribution and intensity in daytime are different from nighttime in beijing city area, the nighttime uhi is obvious. however, in the daytime, the significant uhi mainly appears in the summer, the autumn takes second place, and the uhi in the winter and the spring seem not obvious. the surface evapotranspiration in suburb areas is larger than that in urban areas in the summer, and high latent heat exchange is evident, which leads to lst difference between city area and suburb area. (iii) the reflection of surface landcover categories is sensitive to the uhi, the correlation between vegetation greenness and uhi shows obviously negative, the scatterplot shows that there is the negative correlation between ndvi and lst (r-2 = 0.6481). the results demonstrate that the vegetation greenness is an important factor for reducing the uhi, and large-scale construction of greenbelts can considerably reduce the uhi effect. |
