| 摘 要： | 采用样线法和样方法相结合的调查方法对阴条岭自然保护区的植物种类进行调查。结果表明，保护区共出现种子植物151科815属2576种，表征科有蔷薇科、百合科、忍冬科和樟科，单种科和单种属所占比例较大；在此基础上对阴条岭自然保护区的种子植物区系组成及其特征进行分析，植物区系地理成分多样，以温带成分为主，说明阴条岭自然保护区的区系亚热带向暖温带过渡性质明显，区系指数分析表明：北温带广布、东亚和泛热带分布区类型对阴条岭自然保护区种子植物区系性质的影响极大。

| Abstract: | The seed plants floral composition and characteristics in Yintiaoling Nature Reserve were analyzed based on the field transect inventory. The result showed that there were 151 families of seed plants including 815 genera and 2 576 species in Yintiaoling Nature Reserve. The dominant families are mainly of the following： Resaeea, Liliaceae, Caprifoliaceae and Lauraceae. The rate of single- species families and the monotypic genera was high. The geographic element of the flora was multiplicity, and predominant with temperate floristie element. The flora composition retloeted significant characteristics of transition from Subtropical flora to Warm Temperate zone. The result of flora index showed that the types of N. Temp., E. Asia ＆ N. Amer. disjuncted, Pantropie distributions extremely influenced the characteristic of Yintiaoling Nature Reserve. |
