摘　　要：基于2×2联列表,应用方差分析,χ2统计检验,Ochiai指数,Dice指数和Cramer指数等系列技术,分别对天然毛红椿林群落乔木层树种的总体相关性,乔木层20个优势树种的种间联结显著性和关联强度进行定量的测定。结果表明:该群落多物种总体关联性为显著的正相关,但毛红椿与乔木层植物种间联结性不显著,说明毛红椿的生长与其他乔木树种间没有直接的内在联系。Based on the 2× 2 table, a series of approaches including variance analysis, Х^2- test, association coefficient（AC）, ochiai index （0I）, dice index （DI） and cramer index （CI） were used to analyze the interspecific associations of Toona ciliata var. Pubescens and the upstory plant species in natural forests. The resuits showed that the overall association of all species was obvious association ,but the connections of Toona cil- iata var. Pubescens and the 20 dominant species composing the stratum were not obvious , which indicated that the occurance Toona ciliata var. Pubescens has not direct relevance with the non - host plants.
