  中国横断山地区是古老和孑遗类型动、植物的重要栖息地和天然基因库,是全球地衣物种最丰富的地区之一。随着近年对本地区地衣分类学的深入研究,横断山地衣物种组成多样性及独特性备受关注。在经典分类基础上,结合DNA 现代分子研究技术,围绕横断山主要的三个不同生态区,即:干热河谷区、中高山针阔叶林区和冰缘带地区,分别进行了地衣物种多样性组成及地理分布研究,发现了新属2 个,新种26 个,中国新纪录属5 个,中国新纪录种39个。澄清了本地区的担子地衣、树发群、绵腹衣科,以及柱衣属、条衣属、红盘衣属、金丝属、地茶属、球针叶属等物种组成及地理分布问题,讨论了磷网衣属、泡鳞衣属等属下部分物种的分类界限,为中国植物志的编研和地衣区系研究奠定了基础。
