摘要 以河北省保定市主城区为例,利用Landsat遥感数据对其2001、2009、2017年地表温度进行反演及归一化分级处理,进而研究了地表温度的时空变化。结果表明,辐射传输方程法适用于保定市主城区地表温度反演;保定市主城区热环境分布与城市发展联系密切,热岛区域主要集中在城区中心、周边城镇等人口稠密、建筑密集地区及工业厂区等地;2001—2017年保定市主城区低温区明显减少,中温区不断增加,热岛区域出现了较为明显的破碎化效应。研究结果对保定市主城区热环境分析有一定的参考意义。 By using Landsat remote sensing data,the main urban area of Baoding City in Hebei Province was taken as an example to invert the land surface temperature and grade the normalization results in 2001,2009 and 2017,and then studied the spatial-temporal variation.The results showed that the method of radiative transfer equation is suitable for the land surface temperature in the main urban area of Baoding.The distribution of land surface environment in the main urban area of Baoding is closely related to the urban development.The heat island areas are mainly concentrated in the urban center,around towns and other densely populated,built-up areas and industrial factory areas.From 2001 to 2017,the low temperature area in the main urban area of Baoding decreased obviously,while the medium temperature area increased continuously,and the heat island areas showed obvious fragmentation effect relatively.The results have certain reference significance to the thermal environment analysis on the main urban area of Baoding.
