应用样方法和方差v／均值m比的t检验、聚块指数等研究了广东连州田心自然保护区南方红豆杉（ Taxus wallichiana var．mairei）种群的空间分布格局。结果表明其种群为聚集分布，但聚集程度不高；采用方差比率法（ VR）检验分析红豆杉群落的种间相互关系，结果为VR＞1，χ20.95（N）＜W＜χ20.05（N），表明群落总体是正关联，但不显著；采用Simpson 物种多样性指数和Shannon-Wiener指数分析南方红豆杉群落的丰富度，得到的物种多样性指数整个群落＞草本层＞灌木层＞乔木层的结果，表明群落处于相对稳定状态。结果提示，田心保护区的南方红豆杉现状为增长种群，受2008年初冰冻灾害影响后的自然恢复正朝着良好的方向发展。

The quadrates method , T-test of Mean/Variance and Patchiness indexes were used to analyze the spatial distribution pattern of T.wallichiana var.mairei population in Tianxin Provincial Natural Re-serve of Lianzhou , Guangdong .Results show that the study population is in aggregated pattern of distri -bution, with a low degree of aggregation .In addition, the variance ration (VR) method was used to ana-lyze interspecific relationship of T.wallichiana var.mairei.The result was VR >1, χ20.95 (N) <W<χ20.05(N) , indicating that the community is generally positive but not significant association .Then species diversity indexes of Simpson and Shannon-Wiener were used to analyze the species richness of T.walli-chiana var.mairei community, showing that from arbor layer , shrub layer, herb layer to total communi-ty, the plant species , individual number and species diversity increased , which means that the commu-nity is relative stable in the present stage .The study also showed that T.wallichiana var.mairei popula-tion in Tianxin nature reserves is still growing , even after the influence of early 2008′s icy disaster .
