摘要
应用数量分类(TWINSPAN)和DCA排序方法,对关帝山灌丛草甸群落进行了多元分析,TWINSPAN分类结果表明,该地区亚高山植被可分为灌丛群落、草甸群落2大类,包括8个群落类型,分别位于不同的海拔高度。DCA排序结果与TWINSPAN分类分析结果一致,并可知决定亚高山植物群落类型分布的环境因子主要是海拔高度和地形因子。
Quantitative classification (TWINSPAN) and the DCA (Detrended Correspondence Analysis) sorting method were used to study the distribution patterns of subalpine shrub and meadow land communities on Guandi Mountain. TWINSPAN classification results showed that the subalpine vegetation could be divided into bush and meadowland large groupings, including 8 community types, which are distributed at different altitudes, from 2 500 m to 2 755 m. DCA sorting results were consistent with TWINSPAN classification analysis results, and showed subalpine plant community distribution patterns are correlated with major environmental variables, particularly altitude and topography.
