摘要
对广东省汕头市饶平植物区系组成与基本特点作了研究，饶平区系的表征科为樟科（Ｌａｕｒａｃｅａｅ）、壳斗科（Ｆａｇａｃｅａｅ）、山茶科（Ｔｈｅａｃｅａｅ）、紫金牛科（Ｍｙｒｓｉｎａｃｅａｅ）等，反映了区系的亚热带性质。在饶平植物区系中，热带性和温带性成分均为对本区系的侵入，饶平区系隶属于古热带区系中的华南亚区。阐述了饶平植物区系与相邻地区植物区系之间的联系。
? This paper presents a detailed analysis of the floristic characteristics and phytogeographic composition of Raoping flora. The characteristic families of Raoping flora are the dominant families of South China flora,such as Lauraceae, Fagaceae, Theaceae, Myrsinaceae, Moraceae,Rubiaceae, etc. Most of the floristic elements are tropicalsubtropical elements and this evidently represents the flora's transitional character between tropical and subtropical floras. There are some temperate elements in the flora. Compared with some neighbouring floras,it is shown that the flora of Raoping is closely related to the flora of South China. The flora should be put into Austro-Catheysia belonging to Paleotropical Kingdom. The author also supports the theory of Cathaysian flora.
