摘要:

在鹞落坪保护区设置样方,调查样方内地面生地衣种类和生境指标,探讨森林地面生地衣的分布模式和群落特征。对地衣群落进行了因子分析和排序;应用2×2联表的Fisher精确检验和Spearman秩相关系数进行了种间关联分析。因子分析表明随海拔上升,种类趋于减少,优势种的数目和盖度之间存在显著的正相关(P=0.034),样方湿度和样方生境类型存在极其显著的正相关(P=0.001)。根据组平均分析结果并综合生境特征,将保护区地面生地衣划分为5个群丛类型。Fisher精确检验表明仙人掌绵腹衣Anzia opuntiella与红心黑蜈蚣衣Phaeophyscia erythrocardia等10个种对呈极显著正相关,4个种对呈显著正相关,无显著负相关种对出现。各个地衣种之间的竞争很小。

Abstract:

 Twentynine quadrats belonging to various habitats were sampled in Yaoluoping National Nature Reserve, lichen species in each quadrat were identified and the lichen coverage of each quadrat was measured, combined with several environmental indices, with the purpose of understanding the lichen distributing pattern and community quantitative characteristics. Factor analysis was used to appraise relationships among ecological factors, cluster analysis and Spearman rank correlation coefficient test were employed for ordination and Fisher’s exact test was applied to evaluate interspecific correlation. Factor analysis showed that the number of species decreased as the altitude increased, and there was significant positive correlation between dominant species quantity and coverage (P=0.034), very significant positive correlation between humidity and habitat type (P=0.001). Based on cluster analysis data, twentynine quadrats were divided into 5 types of association. Fisher’s exact test indicates 10 species pairs were very significant positive association and four species pairs significant positive, but no species pair was negative significant association. Fisher’s exact test demonstrated that the competition between the species was low.
