摘要
根据野外调查的样地资料,分析了分布于青海大通东峡林区金露梅灌丛群落的种类组成垂直结构等基本生态学特征,并将金露梅样方以及上层无乔木覆盖灌木为建群层的金露梅样方归为7个群系,对金露梅群落的特征以及株高随海拔梯度的变化作出相应分析。结果表明:该群落种类组成丰富;区系成分以北温带分布为主;生活型以地面芽占优;垂直分化明显;种间联系不紧密。
According to field investigation sample plot material, Potentilla fruticoca brush community＇s species composition, vertical structure and so on ecological characters were analyzed. AndPotentilla fruticoca brush communities were divided into 7 groups that there are not trees upper them. Their community characters and change with altitude were analyzed. The results showed the community apecies compositions are rich. The area ingredients are mainly North Temperate Zone distribution. The vegetative form occupies superiorly by ground buds. The vertical differentiations are obvious. There are not close relationship among species.
