| 摘 要： | 通过多样性指数、植物区系谱、相关分析和聚类分析等方法,对辽宁白石砬子国家级自然保护区植物区系多样性进行定量分析。结果表明:该区植物种类丰富,以被子植物、双子叶植物为主,优势科、属现象明显,单种属和少种属比例较高,有一定残遗性;种的分布型多样,来源较广泛,特有性不明显,区系温带属性较强,热带成分比较少,表明该区温带植物区系历史起源;与相邻植物区系多样性比较,Shannon-Wiener指数差异显著,其中泰山和昆嵛山较高,白石砬子和长白山较低,Simpson指数差异不明显;不同山地植物区系之间相似程度显著,相关系数为0.839～0.995,聚类分析显示:东北和华北植物区系的相似性及纬度分布格局,支持辽东半岛植物小区划归于华北山地植物亚地区的观点。

| Abstract: | The article objective to study diversity of plant floristic, based on floristic spectra, diversity indexes, correlation analysis, and cluster analysis, plant floristic diversity in the Baishilazi National Nature Reserve （NNR） of Liaoning Province was analyzed and compared to adjacent mountains. Results showed an abundance of species in Baishilazi including angiosperms and dicotyledonous plants. It is obvious in the dominant family and genus, angiosperms having a single-species and species with only a few genera were plentiful were showing some relict phenomenon. Distribution types were diverse and complex in the Baishilazi NNR, endemic genera and species were lacking, and tropical elements were few with a greater proportions of taxa belonging to species with temperate characteristics. Compared with adjacent mountains, the Shannon-Wiener index of the floristics was significantly different, whereas the Simpson index was not. The Shannon-Wiener Indexes of Taishan and Kunyushan were high. Correlation of species diversity for different mountains was highly significant（P=0.01）with r between 0.839 and 0.995. The cluster analysis of similarities and latitude patterns for flora of Northeast China, indicated that flora of Liaodong Peninsula in Liaoning Province belonged to the flora of North China. ［Ch, 3 fig. 6 tab. 16 ref.］ |
