| 摘 要： | 对三峡库区柏木林的实地调查和分析表明,三峡库区柏木林可分为11个群落类型,群落成层现象明显,可分为乔木层、灌木层和草本层;物种丰富度、多样性、均匀度在群落梯度上的分布规律均为:灌木层>草本层>乔木层;在海拔梯度上的分布无规律性,这可能与库区内强烈的人为干扰活动有关。

| Abstract: | According to the investigation and analysis of Cupressus funebris forest in the Three Gorges Reservoir Area, there were 11 kinds of community type of Cupressus funebris forest. The vertical structure of the Cupressus funebris community was complicated, it could be divided into tree layer, shrub layer and herbaceous layer; The richness,diversity and evenness of populations in different gradient followed the pattern of shrublayer>tree layer>herbaceous layer,but no pattern was found in altitude gradient. |
