海南霸王岭油丹所在群落的优势种群种间联结性研究
Journal of Tropical and Subtropical Botany（2011）
Abstract
基于2×2联列表,以X2统计量、Ochiai联结测度指数和多物种关联指数为参数,分析了海南霸王岭油丹所在群落中油丹(Alseodaphne hainanensis)等17个主要种群(物种)的种间联结性特征。结果表明,17个主要种群(物种)总体水平上表现为不显著的正联结。17个物种组成的136个种对中:当取样面积在100 m2时,有72对表现正关联,63对为负关联,1对无关联。X2检验有2对表现显著正关联,有3对表现显著或极显著负关联。有125个种对的0More
