摘要
本文以现代化工业城区烟台市福山区为研究区,选取2015年5月Landsat 8 OLI/TIRS多光谱和热红外影像为数据源,采用大气校正法反演地表温度得到地表温度图,结合热岛强度分级指数和土地分类数据,从小尺度城市内部分析城市热岛效应的空间分布特征和土地分类与地表温度之间的相互关系.结果表明:研究区地表温度的高温区主要集中在福山区的北部建城区与裸地,而低温区主要集中在西部和南部郊区的林地、水体和农田周边,城市热岛效应明显,其中建设用地对地表温度的极速升高贡献最大;进一步通过构建热效应贡献度指数,发现商服用地的热效应贡献度明显大于住宅用地.该研究对城市规划和热效应控制有重要参考价值.
Taking Fushan District of a modern industrial city Yantai as the research area and the Landsat 8 OLI/TIRS multi-spectral and thermal infrared images in May 2015 as data sources,the surface temperature map was obtained by the inversion of surface temperature using atmospheric correction method.Combining with the heat island intensity grading index and land classification data,the spatial distribution characteristics of urban heat island effect in city and the relationship between land classification and surface temperature from small-scale city were analyzed.The results indicate that the high temperature areas of the surface temperature in the study area are mainly concentrated in the northern built-up areas and the bare land of Fushan District,while the low temperature areas are mainly concentrated in the western and southern suburbs around forest land,water body and farmland.Urban heat island effect was obvious.The construction land contributes the most to the sharp rise in surface temperature.Further,by constructing the thermal effect contribution index,it is found that the contribution of urban heat island effect of the business place is significantly greater than that of residential land.The research has important reference value for urban planning and thermal effect control.
