摘要: 对暖温带山地针叶林采用无倾向对应分析(DCA)和二元指示种分析(TWINSPAN)进行排序和数量分类。二种方法的分析结果相似。根据暖温带森林地区120个气象站数据,得出多元回归方程,并根据每个样地所在地的经度、纬度和海拔高度,获得各类植物群落气候因子的信息。低山侧柏(Platycladus orientalis)林和油松(Pinus tabulaeformis)林是喜暖耐旱的植物群落。实质上油松林分布很广,亦能耐寒,并可与多种乔木形成混交林。华山松(pinus armandii)林需要温暖湿润的生境,多见于纬度较低的中山地带。亚高山带主要是华北落叶松(Larix princiois-rupprechtii),白扦(Picea meyeri)青扦(Picea wilsonii)占优势的针叶林,它们有纯林,亦有混交林,对上述植物群落给以环境解释,

Abstract: Detrended correspendence analysis (DCA)and two way indicator species analysis (TWlNSPAN) are adopted for ordination and classification of montane coniferous forests in warm-temperate region. Two methods gave similar results. The data from 120 meteorological station in the warm temperate region of China are sued to get the multiple regression for estimating the climatic information of various coniferous forests using longitude, latitude and altitude as predictors. Platycladus orientalis forest and Pinus tebulaeformis forests in the low mountains are forests those can tolerante drier habitat. Actually, Pinus tabulaeformis widespreads from low to mid-montane belts, this kind of Pinus can constitutes different mixed forests with other coniferous and broadleaved trees. Pinus armandii forest adapts warm and moist site. The subalpine forests dominated by Larix principis-rupprechtii, Picea meyeri, P. wilsonii occur in the cold and moist habitat. The environmental interpretation of coniferous forests are mentioned.
