岩下大鲵自然保护区蕨类植物种类较多,但对本区蕨类植物一直未进行过系统的调查和研究,笔者于2007年8月、10月对该保护区蕨类植物进行调查,共采集标本250余号,并对其物种组成进行初步分析,旨在弄清该区蕨类植物的物种组成,为该区域蕨类植物多样性保护与利用提供参考。
1自然概况
岩下大鲵自然保护区位于贵州省黔南最高峰斗蓬山原始森林下的贵定县岩下乡,地理位置东经107°14′23.5",北纬26°35′8.8",海拔1150m;年日照时间677.4~1067.6h,年降水量1100~1200mm,雨量充沛;年平均气温12℃。境内植被为常绿阔叶林;典型的喀斯特岩溶地貌,整体气候温凉湿润[1]。
2蕨类植物名录及物种组成
经统计,在岩下大鲵自然保护区共采集蕨类标本250余号,通过逐一鉴定[2~3],得到蕨类植物26科,55属,117种;此次采集的标本均保存在贵州大学生命科学学院植物标本室(GACP)。
