摘　　要：通过对福建三明中村毛竹林内竹刺瘿螨 (Aculus bambusae Kuang)种群的系统跟踪调查 ,调查结果表明 :竹刺瘿螨种群数量年周期中有 2个高峰期 ,分别为 7月和 10月 ,8月为明显的低谷期。灰色关联分析表明 :所选择的 8个林分因子对竹刺瘿螨种群动态的影响大小序列为林下植物盖度 >竹林坡度>立竹密度 >新竹高度 >新竹胸径 >2 a竹胸径 >2 a竹高度 >小年竹与大年竹比例 ;7个气象因子对竹刺瘿螨种群动态的影响大小序列为平均相对湿度 >月降雨天数 >月极端高温 >月日照时数 >月平均温度 >月降雨量 >月极端低温。The dynamics of Aculus bambusae Kuang population was systematically trailed in Phyllostachys heterocycla cv pubescens forests in Zhongchun,Sanming,Fujian from 2001 to 2002. The results indicated that in a year there were two peaking periods, i.e., July and October respectively, for the occurrence of the harmful mite. The results of gray theory analysis showed that the influences of forest factors in descending order was as follows: coverage of undergrowth vegetation >gradient of stands>density of bamboos>height of new bamboos> diameter of new bamboos>diameter of 2-year-old bamboos>height of 2-year-old bamboos>proportion of good-year to poor-year bamboos. While the influences of climate factors in descending order was as follows: average humidity>monthly raining days>monthly highest temperature>monthly sunshine hours>monthly average temperature>monthly rainfall>monthly lowest temperature.
