【摘要】 崂山植物区系是山东半岛植物区系的典型代表之一 ,具有以下特征 :植物种类比较丰富 ,共计有维管植物 1 2 9科 ,5 1 7属 ,1 0 4 5种 ;优势科现象明显 ;种的特有现象明显 ;植物区系具有古老性 ,单种属和寡种属数量较多 ;分布类型多样 ,地理成分复杂 ,温带成分优势明显 ,泛热带成分丰富 ,与热带植物区系有一定的联系。将崂山植物区系与邻近植物区系进行了属、种相似性系数和优势科的比较 ,表明崂山植物区系与千山、小五台山植物区系的差异较大。区系资料支持将崂山与昆嵛山归属于鲁东丘陵植物小区 ,但也存在一定的差别。更多还原

【Abstract】 The flora of Laoshan Mountain is one of the typical representatives of Shandong Peninsula with some characteristics as follows:it is abundant in species,containing 1045 species of 517 genera,belonging to 129 families.It is notable in dominant family phenomenon;phenomenon of endemic species is obvious;the flora is ancient and single-species and few-species genera of the angiosperm are rich;the types of distribution are various and geographical elements are complex,and dominance of temperate elements is obvious and subtropical elements are plentiful,and it has something in common with tropical flora.The comparison of dominant families of five floras and the similarity coefficient of genera and species are made between Laoshan Mountain and neighbouring mountains.The preliminary results show that the difference of plant floras among Laoshan Mountain,Qianshan Mountain and Xiaowutaishan Mountain is obvious.Floristic data support that Kunyushan Mountain and Laoshan Mountain all belong to the Minor Plant District of the East Lu Hill,but there is certain difference between them.更多还原
