    摘要:通过资源调查以及资料查阅,统计出河南野生常绿阔叶木本植物计34科58属145种。34科分成9个分布类型,其中分布最多的为泛热带(32.35%)及北温带(23.52%),其次为世界分布(14.70%);58属分成14个分布类型,其中分布最多的为泛热带(17.24%)和东亚—北美间断(17.24%),其次为热带亚洲分布(12.07%)。河南野生常绿阔叶木本植物区系亚热带成分较高,同时又有大量温带成分,过渡特征明显。根据其区系分布和适应性等特点,提出优良种类的筛选和园林应用建议。

    Abstract:The investigations of plant resources and consultation data shows that there are 145 species of wild evergreen broad-leaved woody plants, belonging to 34 families and 58 genera. Floristic study shows that 34 families can be classified into 9 areal types with Pantropic (32.35%) and N. Temp. (23.52%) and Cosmopolitan (14.70%) distribution pattern; 58 genera can be classified into 14 areal types with Pantropic (17.24%) and E. Asia & N. Amer. (17.24%), Trop. Asia (12.07%) and E. Asia (12.50%) distribution pattern. The flora of wild evergreen broad-leaved woody plants in Henan has highest percentage of Pantropic distribution elements and many Temp. elements which shows the obvious character of transition. At the end, some suggestions are given on the protection and exploitation of the resources according to the flora and distribution.
