摘要
对天目山脉北部余脉地区进行为期5年的竹类植物调查,并进行分析研究,认为该地区竹类植物区系具有以下几个特征:①本区竹类植物区系在“属”级和“种”级上均为亚热带性质;②种类比较丰富,共有竹类7属40种5变种18变型,是安徽竹类植物最丰富的地区;③以散生竹种为主,丛生竹类很少,是刚竹属和短穗竹属的重要分化变异中心;④地理成分复杂,东西或南北起源的一些竹种相互渗透交汇,具一定的过渡性特征;⑤缺乏竹类系统发育上古老原始的类群,属年轻的衍生区系;⑥特有成分较多。
5 years investigations and analysis on bamboo plants in the north part of Tianmushan Mountains resulted some characters of this bamboo flora: 1. this bamboo flora possese subtropical nature on the genus or species; 2. rich in bamboo resources which take up 72.7% of that in Anhui province, with 40 species, 5 varieties and 18 forma of 7 genera; 3. scattered bamboo are dominant, clumping ones are rather poor in this flora where is the differen- tiation and variation center of Phyllostachys and Brachystachyum; 4. complex phytogeographical elements, some species originated from east china and central china intersected in the flora with a charater of passage; 5. shortage of ancient and primitive groups, belongs to young derived flora; 6. rich in endemic element.
