目的:调查特殊坑道鼠害状况,并制定防制对策。方法:按坑道所属部队和所处战区不同,将5个驻区43条特殊坑道分为一、二、三、四、五组;用粉迹法进行坑道鼠密度调查,现场查看坑道防鼠建筑的安装、使用和管理情况,向坑道作业人员收集鼠类活动的有关资料。结果:被调查的5个组别的特殊坑道鼠密度分别为7.54％、35.56％、2.41％、0、1.05％;安装防鼠建筑的2个组别的坑道鼠密度较另外2个未安装防鼠建筑组低,其中,三组分别与一组、二组坑道鼠密度比较,相差非常显著（P<0.01）。防鼠设施安装率与鼠密度值、鼠咬痕和鼠粪数量成负相关;现场监测的有鼠坑道数与坑道作业人员反映的情况基本一致。结论:部分特殊坑道的鼠害比较严重,防制鼠害任务比较艰巨,应采取综合措施。对所有坑道都应安装防鼠设施,对已有的防鼠设施,应经常检查,发现漏洞,及时整修。
Objective: To investigate the status of rodent pests in special tunnels and to develop control measures. Methods: According to the different units of the tunnel and the battle area, 43 special tunnels in 5 areas were divided into 1, 2, 3, 4 and 5 groups. The moxa method was used to investigate the density of tunnel rats. The installation, use and management of the situation, to the tunnel workers to collect information on rodent activities. Results: The rat density of the special tunnels in the five groups were 7.54%, 35.56%, 2.41%, 0,1.05% respectively. The density of the two groups of rats in rodent-protected buildings was lower than that in the other two uninstalled There was a significant difference between the two groups (P <0.01). The installation rate of rodent prevention equipment was negatively correlated with the rodent density, rat bite marks and the number of rodents. The number of rodents monitored by the site was basically the same as that reflected by the tunnel workers. Conclusion: Some special tunnels have relatively serious rodent infestation and the task of rodent control is arduous. Comprehensive measures should be taken. For all tunnels should be installed rodent control facilities, the existing anti-rodent facilities, should always check and find loopholes, timely renovation.
