| 摘 要： | 经实地调查、采集、鉴定标本,在前人研究的基础上,分析了湖南省气候及地理条件对木兰科植物种类及分布的影响.结果表明;湖南木兰科植物有33种1亚种,湖南是我国木兰科植物现代分布中心之一;木兰科植物在湖南省大部分地区虽有分布,但明显形成湘南与湘西两个分布带,湘西木兰科植物比湘南贫乏,湘南的南岭山地集中了湖南近70％的木兰科植物,南岭是我国木兰科植物的起源与发展中心之一;木兰科植物在湖南的垂直分布范围为海拔200～2000m,绝大部分种（28种1亚种）分布于中海拔（500～1200m）范围内.并在某些方面提出了前人研究结果相异的观点.

| Abstract: | Having fulfilled the work of field investigation,specimen collection and specimen identification,authors of this paper analysed the effects of climate and geographical conditions on the species and distribution of Magnoliaceae plants in Hunan Province. Hunan Province is one of the modern distributive centers of Magnoliaceae plants in China,with 33 species and 1 subspecies. Magnoliaceae plants grow in most areas of Hunan Province,but merely in two distributive zones i. e. the southern zone and western zone.The western zone has few Magnoliaceae plants than the southern zone. Nanling mountain areas in the southern zone are one of origins and development centers of Magnoliaceae plants in China. About 70% of Magnoliaceae plants in Hunan Province grows there. The vertical distributive scope of Magnoliaceae plants in Hunan Province is from 200 to 2 000 meters above sea level; most of the species (28 species and 1 subspecies) are distributed in the scope of 500-1 200 meters above sea level. This paper also puts forward some ideas about Magnoliaceas plants which are different from early ones. |
