| 摘 要： | 介绍了延河流域主要植物的光谱特征,分析了形成植物光谱特征差异的主要内在原因和影响因素,即植物体内的叶绿素(维生素a,b)、胡萝卜素、氮、木质素、纤维素的含量是决定植物光谱特征的根本因素,植被覆盖度、太阳高度角、大气特征、背景地物、观测几何及植被的生长阶段等是植物光谱特征差异的主要影响因素.

| Abstract: | This paper introducs the spectral character of main vegetations along Yanhe river, which are determined by the contents of many materials within vegetations, such as chlorophyll, carotenoids, nitrogen, lignin and cellulose. The spectra are also affected by many factors, like Leaf Area Index, sun's position, atmosphere condition, background character, observation geometry and growthing period of vegetations. |
