| 摘 要： | 采用种群动态分析方法,分析了内蒙古典型草原区布氏田鼠防治经济阈值.结果表明,1995 ～2005年间布氏田鼠(Lasiopodomys brandtii)早春化学防治的经济阈值分别为36.4、48.8、45.2、39.6、51.2、51.7、48.6、47.2、45.4、40.8、40.1只/hm2,而2010 ～ 2012年间的经济阈值则为41.8、39.8、38.7只/hm2.1995～2012年间,布氏田鼠防治的经济阈值基本稳定在45只/hm2左右.布氏田鼠鼠害的防治经济阈值主要受牧羊放牧收益、灭鼠成本和灭鼠成效的影响,牧羊年均放牧收益与布氏田鼠早春防治经济阈值呈反比关系.根据2010～2012年间的调查结果,近年来布氏田鼠早春防治经济阈值的参考数值为40只/hm2. |

| Abstract: | The economical threshold of Brandt's Vole (Lasiopodomys brandtii) was analyzed in the typical steppe in Inner Mongolia. Results showed that the economical threshold of vole fluctuated from 1995 to 2012. From 1995 to 2005, the economical threshold is 36.4, 48.8, 45.2, 39.6, 51.2, 51.7, 48.6, 47.2, 45.4, 40.8, and 40.1 voles per hectare, and from 2010 to 2012, the economical threshold is 41.8, 39.8, 38.7 voles per hectare respectively. The economical threshold of voles is mainly affected by two factors: the annual income to herd a sheep and the character of the population dynamic of voles in current year. The relationship of the annual income of sheep-herding and the economical threshold is inverse proportion. Based on the results from 2010 to 2012, the economical threshold of Brandt's Vole is about 40 individuals per hectare in recent years. |
