摘　　要：为了查明新疆托木尔峰国家级自然保护区树附生地衣群落的空间分布规律,在保护区的不同海拔随机设计样点,进行树附生地衣的生态调查,以地衣盖度为指标应用典范对应分析揭示树附生地衣群落物种分布与环境因子之间的关系。结果表明,15个样点中共得出31种树附生地衣,地衣群落结构主要受海拔、湿度、郁闭度和光照强度的强烈影响,并随这些因素的变化表现出一定的空间差异,说明保护区附生地衣的群落变化和空间分布与这些环境因子高度相关。此外,某些地衣可能受全球暖化和气候干旱化的潜在威胁,增加森林盖度和生境湿度是保护地衣资源的有效措施。In order to better understand the epiphytic lichen species distribution patterns and their relationship with environmental factors, an investigation was conducted in 15 sampling plots randomly designed at different altitudes in Tumur Peak National Nature Reserve. Canonical correspondence analysis was performed using coverage of 31 lichens and 5 environmental factors. The results showed that lichens were different in abundance and spatial distribution in response to changes of four environmental factors, including altitude, humidity, light intensity and canopy density. Some lichens may be potentially threatened by global warming and aridification. Increasing canopy density and habitat moisture could be effective conservation strategies for these lichens.
