摘　　要：依据改进的邻体干扰模型,利用喀斯特适生竹种小蓬竹样地实际调查的基株与邻体的数据,研究基株竹高、冠幅以及枝下高与干扰指数的关系,结果表明:基株的冠幅、树高与枝下高与干扰指数之间呈显著的负相关关系。不同样地因为密度不同,相同因子相同数值决定的干扰指数不一样。该研究结果为合理营造和经营竹类林分提供理论依据。According to an improved neighborhood interference model,the practical data of cardinal and neighbor trees in plots of Drepanostachyum luodianense(Yi et R.S Wang) Keng f were used to study the relationship between interference index and DBH(the diameter at breast height),tree height,the height of first branch.the results showed that the interference index was negatively correlated with crown size,tree height and the height of first branch.Because of the different density in the different sample plots,the in...
