摘　　要：研究了水生植物与水体混合像元的反射高光谱特征,并设计了一个3因素2水平的正交试验,F检验表明:对于单因素,波段和混合像元面积比均对混合像元的反射高光谱影响显著,而探测角不显著;对于交互作用,则波段与混合像元面积比、探测角与混合像元面积比也均对反射高光谱影响显著,而探测角与波段不显著。本文对影响混合像元反射高光谱特征的因素及其交互作用进行了定量分析,为混合像元的深入研究提供了一种新的方法。A study on the reflected and hyperspectral mixed-pixel of aquatic plants and water was given by using a orthogonal experimental design with three factors and two levels.The results of F test suggest that for the single factors,the band and the area ratio of mixed-pixel on the reflected and hyperspectral mixed-pixel of the reflection effects are particularly significant,however,the detector angle had no significant effect under these experimental conditions;For the interaction,the band and the area ratio of mixed-pixel,the detector and the area ratio of mixed-pixel,the effects of these two interactions on the reflected and hyperspectral mixed-pixel are also particularly significant,This study did quantitative analysis of the factors affecting the reflected and hyperspectral mixed-pixel character and their interaction,and provided a new method for the indepth study of mixed-pixel.
