摘要
农田小麦的反射光谱与热红外温度的测定表明,作物生长愈好,其对可见光中的蓝紫光与红光反射愈低,而对近红外反射愈高;而对中红外的反射与热红外的发射则与作物含水情况呈反相关的趋势。农作物的这些光谱特征,构成了农田作物遥感监测的基础。
The reflectance spectra and the heat--IR Observation of wheat in field indicate that the better the crop is growing, the lower the reflectance of visible light, but the higher the near--IR reflectance. However, the reflectance of middle--IR and the emission of heat--IR tendto be inversely correlated with crop water content. These spectral charactristics form a basef or remote sensing monitor of crops in field.
