| 摘 要： | 通过划分2002—2010年云南、广西、贵州、四川、重庆的干旱等级，并分析干旱等级与松墨天牛、马尾松毛虫、松纵坑切梢小蠹、蜀柏毒蛾4种主要林业有害生物发生面积的相关性，结果发现，松墨天牛发生面积与干旱等级的相关性未达到显著水平（P＞0.05），云南纵坑切梢小蠹发生面积与干旱等级呈负相关（P＜0.05），贵州马尾松毛虫发生面积、四川和重庆蜀柏毒蛾发生面积与干旱等级呈正相关（P＜0.01）。因干旱类型、等级及发生地区不同，干旱对林业有害生物发生的影响也不同。

| Abstract: | The drought levels from 2002 to 2010 in Yunnan, Guangxi, Guizhou, Sichuan provinces and Chongqing Municipality were classified in purpose to analyze the correlation of the drought extent with the occurrence areas of four major forest pests including Monochamus alternatus, Dendrolimus punctatus, Tomicus piniperda, and Parocneria orienta. The results showed that there was no significant correlation between the drought level and the occurrence area of Monochamus alternatus (P＞0.05); there was negative correlation between the drought level and the occurrence area of Tomicus piniperda (P＜0.05); there was positive correlation between the drought level and the occurrence area of Dendrolimus punctatus in Guizhou, and there was positive correlation between the drought level and the occurrence area of Parocneria orienta in Sichuan and Chongqing（P＜0.01）. The influence of drought on forest pests varied from the drought type, drought extent, and the region that was impacted by the drought. |
