摘　　要：山东省位于我国东部,总面积为15.3万km2,有较为丰富的植物资源.通过野外采集及标本的整理鉴定,初步确认该区共有野生分布种子植物147科.根据对山东省种子植物科的地理成分分析的结果,得出以下结论:(1)山东省植物区系来源于地史上的劳亚古陆,属于华北植物区系的一部分,科的类型繁多,种类丰富;(2)科级别中区系成分复杂,分布类型多样化,具有明显的热带性亲缘;(3)古老原始类型不丰富,缺乏特有科,特有现象不明显;(4)因科进化的保守性,科的地理成分并不能完全反映出该区种子植物区系的本质特征,必须要结合属和种的地理成分综合来分析.Shandong Province is located in the East of China, have an area of 1.53×105 km2.It is rich in the resources of wild plants. The paper aims at analyzing the areal-types of family of wild seed plants in Shandong Province by means of investigating in the wild field and looking up and arranging and identificating the specimens from several reated specimen room. The results obtained are as follows： （1） In Shandong Province flora comes from the ancient land on the geologic cosmopolitan, belongs to north China flora, part of the wild distribution plant 147 families, diverse species; （2） the level of composition, the central complex, distribution types diversification, has the obvious tropical blood; （3） ancient primitive type is not rich, lack of unique families, the special phenomenon is not obvious;（4） for families of the evolution of conservative, families cannot completely geographical elements reflects the essential feature of the flora, want to combine the geographical composition of and kind of comprehensive analysis.
