摘要：

为了深入探讨和认识红脂大小蠹暴发的深层原因，笔者以其危害严重的山西省吕梁山、中条山和太行山为例，选取适当的代表站点，利用1957—2005年降水、气温、湿度、日照、风等气象资料、相关红脂大小蠹观测资料以及生态环境质量资料，采用气候诊断分析方法，对气候变化以及生态环境质量改变对红脂大小蠹生存环境、生活习性、危害的影响进行综合分析。结果表明：（1）迁徙地气候特点与原产地气候特点极其相似，为该虫的生存繁殖提供了最基本的生态条件。（2）气候变化导致出现适宜于红脂大小蠹发生的气候条件，是红脂大小蠹暴发的重要原因。（3）生态环境质量的下降，是导致红脂大小蠹发生的环境原因之一。因此，积极应对和减缓气候变化，提高和改善生态环境质量，以遏制外来入侵有害生物的泛滥。

Abstract:

In order to explore deeper reason about Dendrkctomus valens LeConte’s outbreaking, the Luliang, Zhongtiao and Taihang mountain in Shanxi province, appropriate representative sites were chosen, using rain, temperature, humidity, light and wind data from 1957 to 2005, observation data of Dendrkctomus valens LeConte, and quality data of ecological environment, the influence of climate changes on Dendrkctomus valens LeConte were analyzed by climate diagnosis. All showed that: (1) In migration, there were similar climate characteristics with its origin, which provided the most basic survival condition for Dendrkctomus valens LeConte. (2) It was the most important reason for Dendrkctomus valens LeConte’s outbreak which were appropriate climate condition caused by climate changes. (3) Quality down of ecological environment was one of important reason for Dendrkctomus valens LeConte. To contain hazardous biological invasion spreading, people should actively face and mitigate climate change, and improve ecological environment quality.
