二滩水库区陆生植物群落物种多样性研究

STUDIES ON SPECIES DIVERSITY OF TERRESTRIAL PLANT COMMUNITIES IN ERTAN RESERVOIR AREA

对二滩水库区典型植被群落类型的物种多样性分析表明，无论是α－多样性还是β－多样性，均以阔叶林为最高，其中尤以常绿阔叶林为最，其次是以云南松林为代表的针叶林；亚高山灌丛。

The analysis of the species diversity of typical terrestrial plant communities distributed within Ertan Reservoir area shows that ,the broad-leaved forests have higher diversity among all kinds of vegetation types of the region,especially,the evergreen broad-leaved forests are the highest ones either α or β diversity levels,the Yunnan pine forests take the second,while the subalpine shrubs and the shrubs and grasslands with sparse trees have lower diversity.
