摘　　要：为了监测武夷山景区松墨天牛Monochamus alternatusHope的发生,防范松材松材线虫Bursaphe lonchusxylophilus病的入侵,于2005-2007年每年4-9月,在武夷山景区10个地点进行了调查,研究了气象因素和环境因素对松墨天牛数量变化的综合影响规律及其程度,对调查结果进行了矢量递进因子分析。结果表明:环境因子和气象因子是松墨天牛羽化孔数和诱集成虫数变化的主要因素,影响松墨天牛成虫诱集数的环境因子按重要性排列依次为:郁闭度、地被物覆盖率、海拔、林龄、坡位、坡向和树高;影响羽化孔数的环境因子按重要性排列依次为:郁闭度、地被物覆盖率、树高、林龄、海拔、坡位和坡向。影响松墨天牛诱集成虫数和羽化孔数的气象因子按重要性排列依次为:月平均温度、最高与最低温差、总降雨量(mm)、气压(hpa)和平均湿度(%)。单从环境因子和气象因子的统计数据分析,环境因子的重要性次序是:坡位、郁闭度、地被物覆盖率、海拔(m)、林龄(a)、树高(m)、坡向;气象因子的重要性次序是:气压(hpa)、平均温度(℃)、最高与最低温差(℃)、总降雨量(mm)、平均湿度(%)。按月分析和按年度分析时其相对重要性基本上是一致的。结论认为,环境因子和气象因子对松墨天牛的数量变化有重要影响。In order to mointor the occurrence of the pine sawyer,Monochamus alternatus Hope,and to prevent the incursion of Bursaphelonchus xylophilus,the effects of meteorological factors and environmental factors on population dynamics of M.alternatus was investigated in 10 locations of Wuyishan Scenic Spot from April to September during 2005-2007.The results showed that meteorological factors and environmental factors composed the main factors that caused quantitative changes of trapped adults and emergence holes of M.alternatus by factor analysis of vectorial progression.The importance of environmental factors influencing the amounts of trapped adults and emergence holes of M.alternatus was in the descending order as follows：the monthly mean temperature,the temperature difference,total precipitation,air pressure and the average humidity.When the data of environmental factors and meteorological factors only were analyzed separately,the importance of environmental factors were in the descending order as follows：slope location,canopy density,coverage degree of ground,elevation,stand age,height of trees and slope aspect;the importance of meteorological factors was in the descending order as follows：atmospheric pressure,average temperature,the temperature difference,total precipitation,and average humidity.It is concluded that environmental factors and meteorological factors may influence distinctly on the population dynamics of M.alternatus.
