摘　　要：对海南岛尖峰岭鸡毛松人工林群落主要树种的重要值、总体方差比率及χ2统计量等种间联结性指标进行测定。结果表明,鸡毛松人工群落树木种类丰富,种群间总体上正联结达显著水平,大部分种群种间联结性不显著,独立分布的为多。鸡毛松与极少种群的种间联结性显著,与大部分种群间联结性不显著,体现了鸡毛松较强的生态适应性。海南岛尖峰岭鸡毛松群落已逐渐向天然次生群落演替。A series of parameters for the interspecific correlation of Dacrycarpus imbricatus plantation community,including the importance value ,collectivity variance ratio,and χ2-test based on a 2×2 contingency table,were analyzed.The results showed that tree species was rich and the importance values distribution was dispersive in the community.The positive association of collectivity variance ratio in total was significant and a majority of interspecific associations were unremarkable.Between Dacrycarpus imbricatus and others,a majority of species pairs were not significant association and few were remarkable,which indicated that Dacrycarpus imbricatus has stronger ecological adaptability and the plantation community succession are evolving towards natural secondary forest.
