摘　　要：创建了局部联结度指数构造模型 ,构造了一种与密度相关的联结度指数及相应的显著性检验统计量 ,证明了经典联结度检验统计量是本模型的特例。应用联结度定义研究了帽儿山林场的固定标准地数据 10个树种的联结关系 ,得到了几个有显著联结度的树种关系 ,并检测到白桦与山杨间随年龄而变化的联结关系。The model of part inter-specific association and an inter-specific association index being relative with the density were constructed, and the relevant significance testing statistic was also determined. It is proved that the classical statistic is a special case of this model. The inter-specific associations among ten arboreal species were studied with the permanent sample plot data from Maoershan Forest Farm, and several significant inter-specific associations were obtained. It is detected that the inter-specific association between Betula platyphylla and Populus davidiana changes with forest age.
