| 摘 要： | 将AVHRR第4通道数据经过辐射校正,再计算得到等效辐射亮温。用城市与郊区的亮温之差代表热岛温度,并以摄氏温标表示。采用统计、平面等值线和三维立体等方法,统计分析了成都平原12个城市的热岛最大强度!Tmax;分析了成都市白天和夜间城市热岛的动态变化规律,从宏观上形象地展示了成都平原的城市热岛现象及其特点。研究证明:利用NOAA/热红外遥感数据进行城市热岛效应的快速监测和宏观动态分析是可行的。 |
| 关 键 词： | 城市热岛效应 NOAA/AVHRR 亮温 城市化 成都平原 |

| Abstract: | Radiation of the 4th channel data of AVHRR was adjusted, and luminance temperature of equivalent radiation was acquired through computation. The difference of luminance temperature between urban and suburb was used to stand for heat island temperature and expressed by centigrade temperature. Twelve cities in Chengdu plain, which stand for the largest heat island intensity were analyzed, and heat island dynamic changing rules at day and night was also analyzed through digital statistics method, plane equivalent line and three-dimensional method. Results demonstrated that it is feasible to quickly monitor and macroscopically analyze urban heat island effect using NOAA/AVHRR thermal-infrared remote sensing data. |
| Keywords: | NOAA/AVHRR urban heat island effect black body temperature urbanization Chengdu plain |
