摘　　要：对福建三明14块毛竹Phyllostachys pubescens林试验标准地节肢动物群落及林分因子进行系统调查,采用典型相关性分析了二者之间的关系。结果表明:新竹眉径与竹冠层节肢动物类群均匀度呈正相关,旧竹眉径与林下层节肢动物类群个体数呈正相关;较高的坡度有利于害螨种群的发生;较高的坡度和林下植被盖度有利于蠕须盾蚧Kuwanaspis vermiformis种群的发生;较高的坡度、旧竹株高、立竹密度和低海拔有利于刚竹毒蛾Pantana phyllostachysae种群的发生。在此基础上,提出了有关毛竹叶部害虫控制的林分因子调节措施。Through systematic surveys in 14 selected sampling Phyllostachys pubescens forests in Sanming, Fujian from 2001 to 2002, the canonical correlativity between stand factors and arthropod community was analyzed. The results indicated that the correlation between the diameter of new bamboo and evenness of the arthropods in the canopy was positive and significant, so was the correlation between the diameter of old bamboo and individuals of the arthropods in underlayer. Moreover, the forest stand factor of high gradient benefited the development of the phytophagous mites population, and high gradient and covering degree off undergrowths benefited the development of Kuwanaspis vermiformis population, and high gradient, height of old bamboo and Iow altitude benefited the development of Pantana phyllostachysae population. Based on the study results, the measures of regulating stand factors were put forward to control the pest on the bamboo leaves.
