北京小龙门林场华北落叶松群落特征的研究
A Study on Larix Principis-rupprechtii Community Characteristics at Xiaolongmen Forestry in Beijing
摘要
采用抽样方法对北京小龙门林场地区华北落叶松群落进行调查,分析了华北落叶松群落的种类组成、群落外貌、生活型组成等群落学特征,计测了常见物种的重要值指标,并对华北落叶松群落划分群丛。结果表明：该群落共出现了146种植物,隶属50科,114属。地上芽植物和高位芽植物是该群落优势层片,反映了该地区春季干旱夏季多雨的典型暖温带大陆性季风气候。群落的垂直结构可分为乔木层、灌木层和草本层。根据分类结果,可将华北落叶松群落36个样方划分为8个群丛,基本上代表了本地区华北落叶松群落的群丛类型,具有明确的生态意义。
