摘　　要：通过资源调查统计出镇江市焦山木本植物共97种,隶属于46科79属。46科分为13个分布类型,其中最多的三类为泛热带分布(26.09%)、北温带和南温带间断分布(17.39%)和北温带分布(6.52%)。79属分为19个分布类型,其中最多的三类为北温带分布(27.85%)、东亚和北美间断分布(10.13%)以及泛热带分布和东亚分布(8.86%)。故焦山木本植物具有一定的多样性。其区系在科水平具有明显的泛热带特征,但同时也具有较浓厚的温带成分。但在属水平表现出强烈的温带特征。同时,焦山木本植物区系与其周围山脉(特别是宝华山)木本植物区系具有较高的相关性和相似度。This study aims to gain insights into the floristic characteristics of woody plants in Mount Jiao via a thor- ough survey. The flora includes 46 families ,79 genera, and 97 species. 46 families were classified into 13 areal types at the family level, among which ＂Pantropic＂ （ 26.09% ）, ＂ N. Temp. ＆ S. Temp. disjuncted＂ （ 17.39% ）, and ＂N. Temp. ＂ （6.52%）are the 3 main types. 79 genera were classified into 19 areal types at the genus level and 3 main types of ＂N. Temp. ＂ （27.85%） ,＂ E. Asia ＆ N. Amer. Disjuncted＂ （ 10. 13% ）, and both ＂Pantropic＂ and ＂E. Asia＂（8.86% ）. These results reveal a certain degree of diversity among the woody plants in Mount Jiao. The floristic characteristics of woody plants in Mount Jiao at the family level exhibit strong pantropic but abundant tem- perate characteristics. The reason might be the mountain＇ s location at the transition zone between subtropical and warm temperate regions. The floristic characteristics of woody plants in Mount Jiao at the genus level display a strong temperate pattern. There is significiant correlations and similarity with the woody plants in circumferential mountains,especially Mount Baohua.
