摘要: 本文利用NOAA卫星AVHRR传感器的5个通道资料,分析了具有不同林木覆盖率的下垫面的绿度值、反射率及温度场。其结果表明:林木覆盖率与绿度值呈正相关;绿度值与反射率呈负相关;绿度值与最高温度呈负相关;反射率与最高温度呈正相关。NOAA卫星资料为今后研究森林对环境的影响提供了一种新的研究方法。

关键词: NOAA卫星资料, 林木覆盖率, 绿度值, 反射率, 温度场

Abstract: The greenness lndices, albedo and temperature field of underlying surface with different forest cover percent were analysed using 5 channels data by NOAA satellite AVHRR transducer. The results showed, The forest cover percent was positive correlation with greenness indices; The greenness indices was negative correlation with the albedo; The greenness indices was negative correlation with maximum temperature; The albedo was positive correlation with maximum temperature. A new method was provided by using NOAA satellite data for studying the effects of forest on environment in the future.

Key words: NOAA satellite data, Forest cover percent, Greenness indices, Albedo, Temperature field
