洪涝灾害破坏了鼠类生存条件,造成大面积鼠类数量急剧减少,幸存鼠类向受灾群众临时居住的高地或堤坝迁移集中,致使驻地鼠密度成倍上升,加上灾民临时驻地人口集中、卫生状况差,鼠类对人类的威胁明显增加。做好洪涝期间的灭鼠工作,是确保大灾后无大疫不可缺少的一环。枞阳县凤仪 Flood disasters destroyed living conditions of rats and resulted in a drastic reduction in the number of large-scale rodents. The migration of surviving rodents to the highways or dams temporarily occupied by the affected people led to a double increase in the density of resident rats. Coupled with the temporary resident population concentration and sanitation Poor condition, the threat of rodents to humans is significantly increased. Doing a good job in rodent control during the flood period is an indispensable part of ensuring no major epidemic after the disaster. Zongyang County Fung Yi
