| 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。

| Abstract: | The community of Larix principis-rupprechtii at Xiaolongmen forestry in Beijing was investigated by sampling method.The community ecological features of the community in species composition,appearance and lifeform composition were analyzed,as well as the major species were evaluated by importance values.The community of Larix principis-rupprechtii was classified into associations,which were named after superior species.The results are as follow.The community is consisted of 146 species,subjected to 50 families and 114 genera.Species of chamaephyte and phanerophytes are showed to the area feature for distribution of Larix principis-rupprechtii community where cold and moist in spring as specifically warm temperature zone monsoon.The vertical structure is made up of arborous,tree and brush layers.In addition,36 sampling plots of community of Larix principis-rupprechtii was classified in to 8 associations,basically representing the associations of Larix principis-rupprechtii at Xiaolongmen forestry in Beijing.This classification is meaningful in ecology. |
