摘要
基于20个样方(各样方面积为25 m×20 m,总面积1 hm2)调查,研究了楚雄花椒园自然保护区元江栲—米饭花林的群落生态学特征。该群落以壳斗科、越桔科、山茶科、八角科、山矾科植物为乔木层主要成分,并以壳斗科植物占绝对优势,群落的物种多样性不高。木本植物以非全缘、革质、常绿、小叶等为其特征,反映该群落生境偏干,为典型的半湿润常绿阔叶林。由于该群落分布海拔较高,林内苔藓类附生植物较多。也存在一些中山湿性常绿阔叶林的常见物种,有向中山湿性常绿阔叶林过渡的特征,是半湿润常绿阔叶林中较为特殊的一个群落类型。
Based on 20 sample plots(the area of each plot is 25 m×20 m,total area is 1 hm2) survey,a synecological study was conducted on the Castanopsis orthacantha-Vaccinium duclouxii community in Huajiaoyuan Nature in Chuxiong prefecture,Yunnan Province.The forest is mainly composed of Fagaceae,Vacciniaceae,Theaceae,Illiciaceae and Symplocaceae,of which Fagaceae is the most dominant family.The species diversity of the forest is relatively low.The forest is characterized by trees with no-entire,leathery and evergreen microphyllous leaves,and considered to be an evergreen broad-leaved forest.However,some species of middle mountain humid evergreen broad-leaved forests occur and epiphytic mosses are abundant in the forest due to its distribution at a higher elevation.The forest is a particular type of semi-humid evergreen broad-leaved forest with some transitional characteristics to the middle mountain humid evergreen broad-leaved forest.
