应用DCA排序方法对天山森林生态系统中朽木生地衣植物的分布格局与海拔之间的相关性进行了分析。结果表明 ,不同海拔高度的不同类型的森林生态系统中分布着不同种类的朽木生地衣植物。分布于海拔 80 0m的主要地衣种类有脱落网衣 (LecidellaelabensFr .,Kgl)、柳茶渍〔Lecanorasaligna (Schrad .)A .Zahlbr〕等。分布于海拔90 0～ 110 0m的有 :刺小孢衣〔Bryoriaconfusa (Awas.)Bodo&Hawksw〕、叉小孢衣〔Bryoriafurcellata (Fr.)Bodo&Hawksw〕等种类。分布于海拔 130 0～ 176 0m的有 :粗皮石蕊〔Cladoniascabriuscula (Del.)Leight.〕、亚鳞石蕊〔Cladoniasubsquamosa (Nyl.)Vain〕等种类 ;分布于海拔 180 0～ 2 30 0m的有 :黑蜈蚣衣〔Phaeophyscianigricans (Flk .)Moberg〕、美丽黑蜈蚣衣〔Phaeophysciarubropulchra (Degel.)Essl.〕等种类。
The correlation between the distribution pattern of dead lichen plants in Tianshan forest ecosystem and the altitude was analyzed by DCA ranking method. The results show that different types of forest lichen lichens distribute in different types of forest ecosystems at different altitudes. The main lichen species distributed at an elevation of 80 ° m are Lecidellae labens Fr., Kgl, Lecanorasaligna (Schrad.) A. Zahlbr, and the like. Distributed at altitudes of 90 0-110 0 m, there are: Bryoriaconfusa (Awas.) Bodo & Hawksw and Bryoria furcellata (Fr.) Bodo & Hawksw. They are distributed at altitudes of 130 0 ~ 176 0m, including Cladoniascabriuscula (Del.) Leight., Cladoniasubsquamosa (Nyl.) Vain, : Phaeophyscianigricans (Flk.) Moberg, Phaeophysciarubropulchra (Degel.) Essl.
