| 摘 要： | 笔者在山西省红脂大小蠹（Dendroctonus valens LeConte）发生地区做了连续调查,结果表明：油松抚育间伐林红脂大小蠹危害重于对照林;割脂与未割脂油松林红脂大小蠹危害差异显著（P=0.001）,割脂油松林红脂大小蠹危害重于未割脂油松林;过火与未过火油松林红脂大小蠹危害差异显著（P=0.014）,过火油松林红脂大小蠹危害重于未过火油松林;油松混交林与油松纯林红脂大小蠹危害无显著差异（P=0.828）,混交林不能减轻红脂大小蠹对油松的危害;不同郁闭度下对应的平均有虫株率不完全相同（P〈0.000 1）,郁闭度为0.3,0.4的林分受害最为严重;阴坡与阳坡油松林红脂大小蠹危害差异显著（P=0.000 1）,阳坡油松林红脂大小蠹危害重于阴坡油松林。

| Abstract: | The author investigates the damage degree of Red Turpentine Beetle(RTB)to Pinus tabulaeformis in Shanxi Province,and analyzes these comparisons between thinned and non-thinned forest,tapped and non-tapped forest,burned and non-burned forest,mixed forest and pure forest,forest with different rate of coverage,sunny slope forest and shady slope forest.The results show that RTB made a greater harm to thinned forest;the difference between tapped and non-tapped forest was significant(P=0.001),RTB had higher harm ... |
