| 摘 要： | 采用植物群落学的原理和方法,对菜阳河自然保护区内的3种主要天然植被物种多样性进行研究 结果表明:植被型相同的群落间物种相似性程度较高,植被型不同的群落间物种相似性系数为山地雨林和季节雨林>山地雨林和季风常绿阔叶林>季节雨林和季风常绿阔叶林 季节雨林群落优势种明显,重要值集中在少数优势种上;山地雨林群落优势种不明显,重要值分布均匀;季风常绿阔叶林群落优势种明显,重要值分布不均匀 山地雨林群落物种丰富,多样性指数明显高于季节雨林群落和季风常绿阔叶林群落 季节雨林在物种多样性上表现最低

| Abstract: | By means of phytocoenological and phytodemographic methods, the species diversity of main natural forests in Caiyanghe nature reserve was studied.The results showed that there were higher species similarities between same communities. In different communities,the species similarities that between montane rain forest and monsoon rain forest>that between montane rain forest and monsoon evergreen broadleaved forest>that between monsoon rain forest and monsoon evergreen broadleaved forest. In monsoon rain forest,the dominant species was evident and the importance value was focused on fewer dominant species;in montane rain forest, the dominant species was not evident and the importance value was even;in monsoon evergreen broadleaved forest,the dominant species was evident and the importance value was not even. Montane rain forest had a larger number of species and its species diversity index was highest among three vegetations. The species diversity index of monsoon rain forest is lowest among three vegetations. |
