015年神农架野外实习小论文江熹霖、许浩铭、李皓 神农架地区树木表面地衣分布影响因素探究 江熹霖*,许浩铭*,李皓* (复旦大学生命科学学院,上海200433) 摘要:地衣对环境中的硫、氮等污染物非常敏感,因此常被作为环境指 示生物。本次野外实习进行的神农架地区环境条件复杂,地衣分布多样 适合进行地衣生长分布情况的研究。我们通过对不同地区的树皮地衣进 行取样统计,分析影响地衣生长分布的主要因素。我们发现海拔对于地 衣分布的影响较少,而光照、树木所处位置、树种对地衣生长有较大影 响。各种因素相互关联,较为复杂,将来需要设计更为细致的实验进行 研究,以确定各种实际因素对于地衣生长的影响。 关键词:神农架,地衣分布,树木表面,影响因素 a research into the influencing factors of lichen distribution on trunks in shennongjia Xilin Jiang*, Haoming Xu**, Hao Li*** School oflife Science, Fudan University, Shanghai 200433 Abstract: Lichen is al ways considered to be indicator organism, because it is ulnerable to nitrogen and sulfur. Shennongjia, which is the destination of our research program, has a complicated landform and varieties of lichens which facilitate our research for lichens. In our experiments, we count lichens on trunks in different areas and try to figure out the main factor affecting the lichens.
