摘要:
 调查2011－2013年中国黑河地区舞毒蛾监测样地的立地和林分因子，分析立地和林分因子及生物多样性指数对舞毒蛾平均虫口密度的影响。结果表明，舞毒蛾平均虫口密度以下坡位立地条件下的显著高于上坡位的；阴坡的显著高于其他的；平坡的显著高于缓坡、斜坡的；海拔301~400 m显著高于401~500 m；林分郁闭度0.5、0.6和0.7显著高于郁闭度0.8；蒙古栎的所占比例＞60%的最高，0~29%次之，30%~59%最低。上坡位、阳坡、斜坡、海拔401~500 m、郁闭度0.8，蒙古栎所占比例30%~59%条件下，舞毒蛾平均虫口密度最小。坡位、坡向对舞毒蛾的平均虫口密度呈正向影响，坡度、海拔、郁闭度、蒙古栎所占比例、Simpson指数、Shannon-Wiener指数对舞毒蛾的平均虫口密度呈负向影响。
Abstract:
 Site and stand factors in monitored sample plots of Lymantria dispar occurring in Heihe area of northern China were investigated from 2011 to 2013.Effects of these factors and the biodiversity index on average population density (APD) of L.dispar were analyzed.One-way analysis of variance (ANOVA) and Turkey tests were adopted for the analysis.The results showed that the APD in down segment of hill slope was significantly higher than that in up segment; significantly higher in shady aspect than in other aspects; significantly higher in flat slope than gentle slope; significantly higher in the elevation of 301-400 m than in above 401-500 m; significantly higher in the forests with canopy densities of 0.5,0.6 and 0.7 than of 0.8.For Quercus mongolica forest,the APD was the highest in the forest in which the proportion of Q.mongolica was 60%,followed by the proportion of 0-29%,and lowest for 30%-59%.The APD was the lowest in upper slope,sunny aspect,steep slope,elevation 401-500 m,canopy density 0.8,and Q.mongolica forest with the proportion of 30%-59%.Slope position and aspect demonstrated positive impact on APD,while gradient,elevation,canopy density,proportion of Q.mongolica,Simpson index and Shannon-Wiener index demonstrated negative impact.
