为了弄清雪峰山西南支脉丘陵山地生态系统的结构、类型及其特性,研究了26个典型森林群落的结构及组成特点.区域内共有植物162科405属759种,主要为热带分布及亚热带分布,其植物区系成分复杂,具有明显的过渡与交汇特征,与其联系最为广泛的是滇、黔、桂区,同时与华中、华南、华东区的联系亦非常密切.从生活型来看,高位芽占的比例最大,中高位芽植物和小高位芽植物为区域内群落乔层的主要组成种类.在层片结构上,森林植物群落除暖性灌丛外,都具有乔木层层片、灌木层层片、草本层层片和苔藓地被层层片,常绿阔叶中高位芽层片为乔木层主要层片,并多构成群落的建群层片.26个群落可分为7个植被类型,分别处于...

In order to rtveal the structure,type and characters of the ecosystem in southwestern upland of Snow Peak Mountain,structures and composing characters of 26 typical flora were studied.The results showed that there were 759 species,405 genus,162 family plants in this area,which were mostly distributed in the tropical and subtropical zone.The flora had obvious characters of transition.The most broad related are unnom Guizhou and Gui Zhun areas.The relationship to central China,southern China and eastern China is also close.For life forms,the most is the phanerophytes.Meso phanerophytes and micro...
