摘　　要：对河南伏牛山常绿阔叶木本植物垂直分布进行分析,结果表明,伏牛山常绿木本植物共计31科、47属、106种及变种;垂直分布范围300～2 300 m;其垂直分布上限范围为500～2 300 m,分布在500～1 000 m的有53种;1 000～1 500 m的19种;1 500～2 000 m的23种;2 000 m以上的9种.垂直分布与生长习性之间存在明显的关系,海拔越高,乔木越少,而且有些乔木种类随海拔的上升而变为灌木.On the basis of former information,the vertical distribution of broad-leaved evergreen woody plants in Funiu Mountain is analysed.The result shows that there are 31 families,47 genera,106 species and varieties;the vertical distribution is between 300 m and 2 300 m;The high vertical distribution is between 500 m and 2 300 m.There are 53 species between 500 m and 1 000 m;19 species between 1 000 m and 1 500 m;23 species between 1 500 m and 2 000 m,9 species above 2 000 m.There are obvious relations between vertical distribution and growth habit,some trees changing into brushes with the change of altitudes.The north boundary of subtropical zone should be between 1 000 and 1 200 m.
