摘要：藤枣(Eleutharrhena macrocarpa)是国家Ⅰ级重点保护植物,属于木质藤本植物,野外数量稀少,种群更新困难。本文通过分析云南省太阳河自然保护区藤枣生境地热带季节雨林乔木层与灌木层中木本植物种群的种间关联性以及群落的稳定性,揭示种间关联性在藤枣种群濒危机制形成中的作用,为极小种群的保护提供科学依据。结果表明:藤枣生境地群落乔木层总体联结性VR(方差比率)>1,检验统计量W>χ0.05(29),灌木层种群总体联结性VR<1,χ0.95(29)Eleutharrhena macrocarpa,an endangered liana species,experiences population regeneration barriers in natural environments.Due to its endangered status,this species has been heavily researched to understand the mechanisms behind its rarity.In this study,we studied E.macrocarpa populations in the tropical seasonal rainforest of Taiyanghe Provincial Nature Reserve in Pu’er City,Yunnan Province to find successful protecting methods for a wild plant species with extremely small populations.Utilizing various community stability and interspecific competition metrics(the Godron stability index,Chi-square analysis,Pearson correlation),the results showed that the woody plant populatios of tree layer indicated significant positive correlation based on the value of variance ratio more than one(test statistic W>χ0.05(29)).Similarly,the woody plant populations of shrub layer indicated that no significant negative correlation and the variance ratio is less than 1(χ0.95(29)
