城市街区尺度地表热环境遥感监测与分析
Remote Sensing Monitoring and Analysis of Surface Thermal Environment at City District Scale
摘要
Abstract
Research on urban thermal environments is mostly focused on large or urban area scales; research on district-scale urban environments is inadequate. In this study, the high-spatial-resolution thermal infrared domain data from the Tiangong-1 satellite was used to retrieve the land surface temperature (LST) of areas in Nanjing based on the JM&S method. The spatial distribution of the land surface thermal environment in Nanjing at night was revealed, and its relationship with the surface cover was analyzed. The difference in LST in different districts at night was observed. Our results show that the high-spatial resolution of Tiangong-1 has thermal anomaly detection abilities, and the heterogeneity of LST is better reflected through it. An obvious urban heat-island effect exists in Nanjing at night with a 2.6 K heat-island intensity. The difference in temperature in different districts is more obvious, which was affected by surface cover, population, and buildings.关键词
