摘　　要：目的立足于我国北方区域性新造林、次生林的不同森林立地条件下,探讨林区鼠害控制标准。方法在蛮汉山林场新造林地和次生林地各选择3块样地,采用毒饵盒法连续3 d调查毒饵取食情况,之后采用夹日法在所选样地连续捕获4 d,计算鼠的捕获率;同时在新造林地和次生林地再分别选择3块样地作为对照区,调查对照区啮齿动物的群落组成及数量。根据灭鼠前后捕获率变化情况计算防治效果。结果在蛮汉山林区,新造林地长尾仓鼠为优势种;次生林地大林姬鼠为优势种。应用PVC毒饵盒以C型肉毒素为毒饵进行林区鼠害防治后,防治区害鼠密度显著低于对照区(F=6.46,P<0.05)。结论C型肉毒素在2块林地均具有较好的适口性和防治效果,可在林区灭鼠中推广应用。Objective To investigate differentiated rodent control standards based on difference between new afforestation and secondary forest in north China. Methods In each of secondary forest and new afforestation in the Manhan Mountain Forest Farm, 3 sample areas and 3 control areas were selected. In the sample areas, a three-day investigation was performed using poison bait box, followed by live trap capture for four days. Capture rate was calculated accordingly. In the control areas, community composition and quantity of rodents were investigated. Control efficacy was evaluated according to the changes in capture rate after deratization. Results Cricetulus longicaudatus was the predominant species in the new afforestation of Manhan Mountain. Apodemus speciosus was the predominant species in the secondary forest. With the use of PVC box containing type C botulinum toxin as poison bait, the population density of rats in sample areas was significantly decreased as compared with that in control areas （F=6.46, P〈0.05）. Conclusion Type C botulinum toxin shows good palatability and rodent control efficacy in the new afforestation and secondary forest, and it can be widely used in the forest region for rodent control.
