| 摘 要： | 运用Landsat TM/ETM+和Terra ASTER数据，对北京市1990~2007年夏季的地表温度进行了反演，并对地表温度的空间分布、时间变化作出了分析。对Landsat TM/ETM+数据的温度反演采用了普适性单波段算法，ASTER数据的温度反演采用了劈窗算法。通过对地表温度数据的直方图均衡处理以及综合对比分析，总结出北京地区历年来夏季地表温度的空间分布格局及该格局随北京城市发展的变化规律，分析了研究成果的不足，提出了下一步要努力的方向。 |

| Abstract: | Utilizing Landsat TM/ETM and Terra ASTER data,the authors retrieved the land surface temperature(LST) of Beijing during the summer of 1990~2007,and analyzed the spatial distribution and temporal variation of LST in the study area.The retrieval of LST from Landsat TM/ETM data applied the generalized single-channel method,while split-window algorithm was introduced to the retrieval from ASTER data.The LST data were converted to histogram equalized maps and then synthetically compared and analyzed.Spatial distribution of LST in the summer of each year as well as the temporal diversion was summarized.It is thus known that the Heat Island Effect has been mitigated since 1999.In the end,the shortcomings in the achievements are analyzed,and the orientation of future work is pointed out as well. |
