摘要
植物的外在表现总是具有独特的光谱属性。因此作物的“苗情长势”可以通过它们的光谱成分分析和植物指数(绿度)间接地得到证实。本文根据冬小麦反射光谱特性,利用一定条件下的NOAA/AVHRR通道1(CH_1,0.58—0.68μm)和通道2(CH_2,0.72—1.1μm)数据。
The relations between greenness and agronomic index of winter wheat are researched, agronomic index of winter wheat growing tendency and meteorological conditions are established, and the criterion of remote sensing macromonitoring greenness index of the growing tendency of winter wheat in different areas and categories is determined.
