| 摘 要： | 针对冀北山地的森林鼠害发生规律及防治措施进行了研究,通过铗捕法和洞口统计法进行鼠害种类及密度的调查;通过踏查确定主要危害树种;采用化学、物理、营林、生物药剂、天敌等5种方法进行了防治效果对比分析。结果表明,该区域威胁森林资源安全的主要鼠害为棕背鼲,油松是其主要为害树种;7月、8月是其为害高峰期,也是防治的关键期;物理防治(树干套管)和营林措施(割灌除草)防治效果最好,分别达到83%和89%,并且具有可操作性,适合大面积推广;天敌防治见效周期较长,是解决森林鼠害的治本之道,但短期效果不太明显,生物药剂防治效果不佳。

| Abstract: | In this paper ,the occurrence and control measures of the forest rodent pest in the mountainous area of northern Hebei Province are studied ,using the trap capture and the sta-tistical method to investigate rodent species and density .Through step-driving investigation the number of main rodent species was determined and prevention effects of five measures in-cluding chemical control ,physical control ,biological agent control ,biological control and silviculture ware comparatively analyzed .The results showed that Clethrionomys ruf ocanus is the main rodent threating the security of regional forest resources and mainly harming pines with the damage peak occuring in July and August as the key prevention and control period .The physical control （stem casing） and silvicultural measure （brush weeding） proved to have the best control effect ,reaching 83% and 89% respectively ,with high maneuver-ability ,and feasibility for generalization in large area w hile biological control as a fundamen-tal solution to the forest rodent pes had a long-term effective cycle ,without obvious effect in the short time .As for the biological agent control it provwed to be the poorest . |
