一、前言 叶绿素在绿色植物的光合作用中起主要作用,有吸收兰、红等可见光,反射绿光及红外光的特征。在遥感信息判读中具有“指示性和干扰性的双重作用”。樟子松是阳性速生、耐干旱脊薄的常绿针叶树种,我国东北北部、内蒙古等地分布有大面积的樟子松纯林与兴安落叶松构成的混交林。研究樟子松的遥感信息与叶绿素的含量的相关性在针叶树中具有代表性的重要意义。 I. Introduction Chlorophyll plays a major role in the photosynthesis of green plants. It has the characteristics of absorbing visible light such as blue and red, and reflecting green and infrared light. In the interpretation of remote sensing information with the “indicative and interference dual role.” Pinus sylvestris is a positive fast-growing, drought-resistant ridges of evergreen conifers, northern China’s northeast, Inner Mongolia and other places distributed a large area of ​​Pinus sylvestris var. Mongolica and mixed forest. The correlation between remote sensing information and chlorophyll content of Pinus sylvestris is representative in conifers.
