摘　　要：【目的】研究黔东南地区巫山淫羊藿(Epimediumwushanense)的自然群落特征,为巫山淫羊藿资源保护和人工种植提供科学依据。【方法】采用样方调查法,对巫山淫羊藿群落基地的区系组成、地理成分、生活型、结构及物种多样性进行统计分析。【结果】该群落内常见的维管植物约有86种,隶属46科68属。热带亚洲(14属)、北温带(13属)分布类型占绝大部分。按Raunkiaer生活型统计,地面芽植物占53.5%,地上芽植物占26.7%,高位芽植物占8.1%,一年生植物占4.7%。群落垂直结构简单,分层不明显,只分为灌木层和草本层,并有少量的层间植物。Shannon-Wiener指数较高,群落中物种比较丰富;Simpson指数和种间相遇机率指数均较低,说明与巫山淫羊藿伴生的植物种类分布不规律,其优势度显著集中在巫山淫羊藿上。【结论】巫山淫羊藿群落目前处于相对不稳定状态,种群还处于建立时期。[Objective]The natural community characteristics of Epimedium wushanense in southeast Guizhou were studied to provide scientific references for its resource protection and artificial planting.[Method]Floristic composition,geographical composition,life form,structure and species diversity of Epimedium wushanense community were analyzed by quadrat survey.[Result]The results showed that there were about 86 common vascular plants belonging to 46 families and 68 genera within the community.And most of them were the distribution type of Tropical Asia （14 genera） and North Temperate （13 genera）.According to Raunkiaer＇s life-form classification,hemicryptophyta,chamaephyte,phanerophyta and therophytes accounted for 53.5％,26.7％,8.1％ and 4.7％,respectively.The vertical structure of the community was simple and there were only shrub layer and herb layer with a few plants between them.Shannon-Wiener index was relatively high,while both interspecific encounter index and Simpson were relatively low,which indicated that the plant community was irregular and its dominance concentrated on Epimedium wushanense.[Conclusion]The community of Epimedium wushanense was not relatively stable and it was at the stage of population establishment.
