中文摘要：
为了探讨雾灵山植物区系的垂直分化特征,结合样带法与样方法,对雾灵山北坡垂直植被带进行了调查,统计得出各垂直植被带的科、属的物种数量,分析了科、属区系成分的构成及其沿海拔梯度的分布格局.结果表明：整个垂直梯度上最重要的植物区系成分是北温带成分,显示了本植物区系的基本性质;其次是世界分布、北温带和南温带间断分布以及旧世界温带分布,温带分布也占一定比例.
英文摘要：
To explore the altitudinal differentiation of flora on the Wuling Mountain, the vertical vegetation zones on the north slope of the Wuling Mountain are investigated. The fleristic components at the level of family and genus are counted. Results show that the North Temperate type is the dominated type in the vertical vegetation zones, which indicate the basic character of in this area. Cosmopolitan, N. Temp. ＆ S. Temp. Disjuncted and Old World Tropics are the second most dominant types and Temp. Asia type is also present for a certain percentage.
