摘　　要：为了解陕西紫茎的群落结构和物种分布机制,采用样地法,对陕西紫茎的群落特征进行研究。结果表明:宝天曼自然保护区陕西紫茎群落物种丰富,植物科属组成较为分散,从属的地理成分上看,温带分布的属占据优势,群落的生活型以高位芽植物为主,群落叶的性质以中型叶、单叶、草质为多,群落结构复杂,具有一定的层间植物;群落乔木层、灌木层和草本层的物种多样性大小依次为灌木层>草本层>乔木层。根据陕西紫茎的观赏特性和生态习性,提出河南省营造陕西紫茎风景林的群落配置方式。In order to understand the community structure and species distribution mechanism of Stewartia shensiensis Chang forest,the community features of Stewartia shensiensis Chang forest were studied by sampling. The results showed that Baotianman Nature Reserve was rich in Stewartia shensiensis Chang forest,which showed scattered composition regarding to plant families. In terms of geographical components of the genera,many of them were distributed in the temperate zone. The main life form of this community was phaenerophyte and middle sized,single,and herbaceous leafs took advantage in the community. The community structure was complicated with certain interstratum plants. The species diversity index of different layers was descending in the following order： shrub layer herb layer tree layer. According to the ornamental characteristics and ecological habits of Stewartia shensiensis Chang,the configuration form of Stewartia shensiensis Chang landscape forest in Henan province was put forward.
