在位于滇东北地区的云南大关三江口自然保护区的亚热带山地常绿阔叶林的森林植被地带,通过对有珙桐种群分布的代表性地段设样地调查的方式,对该自然保护区珙桐种群的分布状态进行了调查研究。其结果表明,在三江口自然保护区珙桐种群多呈散生状,而在局部地段聚集成小片纯林。其种群在一定条件下可实现自然更新。通过调查明晰了该自然保护区珙桐种群所处森林植被的植物物种组成特征及其垂直结构特征。
In the forest vegetation zone of the evergreen broad-leaved forest in the subtropical mountainous area of Sanjiangkou Nature Reserve in Yunnan Daguan, Yunnan Province, a sample survey was conducted on the representative plots of the population distribution of the M. involucrate forest. The distribution of Davidia involucrata population was investigated. The results showed that in the Sanjiangkou Nature Reserve, Davidia involucrata populations mostly appeared as loosely distributed, while in some areas gathered into small pure forests. Its population can be naturally updated under certain conditions. Through the investigation, the species composition and vertical structure of plant species in the forest vegetation of Davidia involucrata forest in the nature reserve were clarified.
