摘 要:
初步分析了鲜为人知的滇西南瑞丽莫里的热带雨林植物区系组成与地理成分。该植物区系中热带和主产热带的科占总科数的80%以上,热带分布属占总属数的84.1%;典型热带分布种占总种数的82.1%,该区系在科、属和种水平上均以热带成分占优势,明显属于热带性质的植物区系。在其热带分布属中,又以热带亚洲分布属最多,占总属数的26.5%;典型热带分布种中也以热带亚洲分布及其变型的种占绝对优势,占总种数的72.9%,反映了该植物区系具有热带亚洲植物区系的性质特点。在其热带亚洲成分中,又具体以南亚-大陆东南亚成分比例最高,反映了滇西南的热带雨林植物区系由于地域邻接关系,受印度(喜马拉雅)-缅甸植物区系的强烈影响。[著者文摘]

Abstract:
A tropical rain forest fragment was recently recognized from Moli, Ruili County in Southwestern Yunnan and its floristic composition was studied. Tropical families contribute to more than 80% ,tropical genera to 84. 1% and tropical species to 82.1% of its total flora,which indicate that the flora of the tropical rain forest in Moll is conspicuously tropical in nature. Among those tropical floristic elements,the ones of tropical Asian genera contribute to 25. 6% of its total genera, and the ones of tropical Asian species contribute to 72.9% of its total species,which shows that the flora has a strong affinity to tropical Asian flora and is part of tropical Asia flora from its northern margin.[著者文摘]
