摘要
【目的】为保护国家二级珍稀濒危保护植物绿花杓兰,对横断山中东部绿花杓兰的核心分布区域进行群落植物多样性研究。【方法】在绿花杓兰热点分布区域横断山中东部地区设置24个样地进行调查,并分析绿花杓兰群落植物的α多样性。【结果】绿花杓兰24个典型代表性样地共有植物95科234属366种。在科、属、种的水平上绿花杓兰岷山山脉群落与大雪山山脉群落间有更高的相似性。岷山山脉群落和大雪山山脉群落的植物多样性显著大于邛崃山脉群落。【结论】横断山中东部地区绿花杓兰群落植物成分复杂多样,与国内其他地区杓兰属植物群落的成分有较大差异,群落物种的地理成分表现出热带亚热带地区向温带过渡的特点。
【Objective】In order to protect the National Second-grade rare and endangered plant Cypripedium henryi,a study was conducted on the plant diversity of the C.henryi community in the core distribution area of Hengduan Mountains.【Method】A total of 24 plots were set up in the hot spots of C.henryi in the Mid-Eastern areas of Hengduan Mountains,and usingαdiversity index,the features of plant diversity were analyzed.【Result】There were 366 species belonging to 95 families and 234 genera in the 24 typical C.henryi plots.At the family,genus and species levels,there were higher similarity between Minshan and Daxueshan communities.Theαdiversity indices between Minshan Mountains and Daxueshan Mountains communities of C.henryi were higher than Qionglai Mountains.【Conclusion】The plant flora elements of C.henryi in the Mid-Eastern areas of Hengduan Mountains were complex and various and exhibited the trend in the transition from tropical-subtropical zones to temperate zones.There were significant differences in the composition of the C.henryi communities compared to other Cypripedium community plants in China.
