山东艾山植物区系研究

艾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96科，311属，488种。该植物区系优势科现象明显；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，温带成分优势明显达161个属，泛热带成分丰富有50个属，热带植物区系为21个属。将艾山植物区系与邻近植物区系的植物地理分布类型进行聚类分析和属、种相似性系数和优势科的比较，结果表明，艾山植物区系与千山植物区系的差异比较大。植物区系资料研究不支持把辽东半岛、山东半岛划为同一植物区系亚地区。

Studies on flora of Aishan Mountain in Shandong Province

The flora of Aishan Mountain is one of the typical representatives of Shandong peninsula with some characteristics as follows:it is abundant in species,containing 488 species of 311 genera,belonging to 96 families.It is notable in dominant family phenomenon;the flora is ancient and single-species and few-species genera of the angiosperm are rich;the areal-types are various and the geographical elements are complex,dominant temperate genera is 161,pantropical genera is 50 and tropical flora is 21.The areal-types of genera of Aishan Mountain flora is compared with neighboring regions (Laoshan Mountain,Kunyu Mountain,Taishan Mountain,Qianshan Mountain,Xiaowutaishan Mountain) using clustering analysis and similarity coefficient of genera and species.The results show that the difference between Aishan Mountain flora and Qianshan Mountain flora was obvious.This result also show that Shangdong peninsula and Liaodong peninsula would not be same subregion.
