Rodent damage poses a significant threat to crops, human life, and health. Compared to chemical rodent control, such as placing poisonous baits, it is more economical and environmentally friendly to use physical methods, such as building a rodent-proof wall. This study introduces a method of physically controlling harmful rodents and four methods of calculating the effect of rodents control. To understand the controlling effect of the rodent-proof wall, an investigation was conducted on the Dongting Lake beach and corresponding farmland in the embankment in April and July 2012. Our findings illustrated that the density of the reed vole Microtus fortis in the farmland with rodent-proof walls was 0.52%, significantly lower than that in the farmland without rodent-proof walls (1.76%) after artificial trapping and drug extermination (χ = 3.900, P = 0.048). The density of M. fortis that had migrated into the farmland in dikes with a rodent-proof wall decreased by 98.53%, significantly higher than the decrease of density in dikes without a rodent-proof wall (86.61%) (χ = 11.060, P = 0.01). The results demonstrated the effectiveness of rodent-proof wall control. Therefore, building a rodent-proof wall should be advocated and vigorously promoted to prevent the migration of rodents into the Dongting Lake area and similar environments, as they cause harm.
啮齿动物的危害极大，会对农作物、人类生命和健康构成严重威胁。与化学灭鼠（如放置毒饵）相比，使用物理方法（如修建防鼠墙）更加经济和环保。本研究介绍了一种物理控制有害啮齿动物的方法和四种计算灭鼠效果的方法。为了了解防鼠墙的控制效果，我们于 2012 年 4 月和 7 月对洞庭湖滩涂和堤岸相应农田进行了调查。结果表明，在人工诱捕和药物灭治后，修建防鼠墙的农田中东方田鼠的密度为 0.52%，显著低于未修建防鼠墙的农田（1.76%）（χ=3.900，P=0.048）。防鼠墙堤段进入农田的东方田鼠密度下降了 98.53%，显著高于未修建防鼠墙堤段的下降率（86.61%）（χ=11.060，P=0.01）。结果表明防鼠墙的控制效果显著。因此，应大力提倡和推广修建防鼠墙，以防止啮齿动物进入洞庭湖地区和类似环境造成危害。
