| 摘 要： | 应用中巴资源卫星热红外遥感数据(CBERS-02 IRMSS)和普适性单通道算法反演福州市的地表温度.反演过程中使用同时相的MODIS数据在像元尺度上获取的大气水汽含量替换标准大气模拟值,参考气候资源评价中人体舒适度指数模型,建立基于地温的热环境评价模型,并对福州城市热环境进行评级.结果表明:中巴资源卫星热红外数据对城市热岛和热环境研究具有重要的应用价值,多源遥感数据的结合可以提高地表温度的反演精度,而基于遥感反演参数的热环境指数评价方法能够较好地描述城市热环境的空间特征.

| Abstract: | The issue of urban thermal environment and urban heat island effect are important contents in urban climate and environmental research.Retrieving and analyzing land surface temperature(LST) is an efficient way to study this issue.In this paper,Fuzhou was taking as typical study area to study LST retrieving and thermal environment evaluation.CBERS-02 IRMSS thermal infrared remote sensing data for generalized single-channel algorithm developed by Jimenez and Sobrino were used to retrieve LST,and MODIS data ac... |
