摘要
经初步研究,大娄山脉共有野生药用维管植物215科1130属4277种,含40种以上的优势科有30科,共602属2505种,分别占本区系科、属、种的14.0%、53.3%和58.6%。区系分析结果表明,大娄山脉药用维管植物种类丰富,地理成分十分复杂,区系起源古老,特有种类丰富,温带成分和热带成分相互交错,偏向温带性质,温带分布550属,不计世界分布属,占属数的53.0%;热带分布487属,占属数的47.0%,与大娄山脉气候由亚热带向温带过渡有关,也与我国许多亚热带区域温带性质属、种反而占多数的现象相符合。
After the preliminary research,there are 4277 species of medicinal vascular plants belonging to 1130 genera and 215 families in Daloushan Mountains.There are 30 families whose species are over 40.These families include 602 genera and 2505 species,accounting for 53.3% of the total genera and 58.6% of the total species.The analysis of genera of medicinal vascular plants showed that the areal-types were very complicated in Daloushan Mountains.As far as the origin of plants is concermed,it＇s rich in peculiar species.Temperate elements and tropical elements infiltrate each other,but like the former a little more.Excluding the genera of world distribution,there are 550 genera of temperate elements and 487 genera of tropical elements,accounting for 53.0% and 47.0% of the genera respectively.The phenomenon was relative to the climates in Daloushan Mountains that transit from subtropical zone to temperate zone,and was consistent with the phenomenon that temperate genera are more than tropical genera in most subtropical area of china.
