| 摘 要： | 为探明萧氏松茎象的种群变化规律,于2005年4月-2007年9月,在武夷山风景区选择11块标准地进行定位观测,采用综合相关系数法分析该虫种群与环境因子的关系.结果表明:林分因子对萧氏松茎象的种群动态有极显著影响(R=0.861 9,P<0.001),其重要性依次为:地被物覆盖率、坡位、坡向、树高、海拔、郁闭度和林龄.气象因子也有显著影响(R=-0.530 9,P<0.05),其重要性依次为:平均湿度、总降雨量、平均温度、极端温差和气压.萧氏松茎象主要为害胸径为21～60 cm区段的松树.松树胸径与虫口密度间有极显著的相关性.综上,环境因子对萧氏松茎象有重要影响.本文提出的综合相关系数分析法,具有一定的创新性和实用性. |

| Abstract: | In order to clarify the change characteristic of Hylobitelus xiaoi population,a field observation was conducted in 11 plots in Wuyishan scenic region from 2005 to 2007,and the collected data were used to further analyzed the relationship between population and environmental factors by using an integrated correlative method.The selected forest factors had marked influence on Hylobitelus xiaoi population dynamics(R = 0.861 9,P < 0.001),and their importance was in an order of coverage,slope location,slope dire... |
