摘要
以小陇山林区蕙兰为研究对象,通过野外调查观测,分析了蕙兰在小陇山林区的分布情况及群落结构特征。结果表明：1）蕙兰分布于106°10′169″-106°21′643″E、33°44′526″-34°08′903″N范围内,海拔925-1 350 m之间;2）蕙兰多生于次生阔叶林,常绿、落叶阔叶混交林或常绿针阔混交林下,坡度17°-47°之间;3）蕙兰呈团块状不连续分布。
Taking Cypripedium faberi in Xiaolongshan forest area as study object,based on the field investigation and observation,the distribution and community structure characteristics of Cypripedium faberi in Xiaolongshan forest area were analyzed.The results showed： 1） The distribution range of Cypripedium faberi was 106°10′169″～106°21′643″E,33°44′526″～34°08′903″N,and elevation range was 9925～1 350 m;2） Cypripedium faberi species were born in secondary broadleaved forest,evergreen and deciduous broad-leaved mixed forest or evergreen coniferous and broad-leaved mixed forest,and slope was 17°～47°;3） Cypripedium faberi showed mass and discontinuous distribution.
