浙江省2010年鼠类种群密度与季节消长监测分析

目的通过对浙江省鼠类监测结果分析,掌握鼠类种群分布和季节性消长等动态变化规律,为浙江省鼠类及其传播疾病的控制提供依据。方法采用夹夜法进行鼠密度监测,每月1次,每个监测点分居民区、特殊行业和农村自然村3个监测类型。结果 2010年浙江省主要优势鼠种为褐家鼠,其次为小家鼠和黄胸鼠。全省平均鼠形动物密度为0.97只/100夹,农村自然村鼠形动物密度相对较高,平均为1.23只/100夹。杭州、海盐地区以小家鼠为优势种,衢州地区以黄胸鼠为优势种。鼠类季节消长曲线呈双峰型;江山市监测点鼠密度最高。结论浙江省存在多种媒介鼠,建议加强鼠类综合监测,降低鼠密度,控制鼠传疾病。

Rodent population density and seasonal fluctuation in Zhejiang in 2010

Objective To get an insight into the distribution and seasonal fluctuation of rodent population and provide the basis for the control of rodents and rodent-borne diseases in Zhejiang province.Methods Rodent density surveillance was conducted once a month by night trapping method, with each surveillanc site covering a residential area, a special industry and a natural rural village.Results It was found thatRattus norvegicuswas the predominant species in most areas of Zhejiang province in 2010, followed byMus musculusandR. tanezumi. The average rodent density in the province was 0.97 per 100 rat traps, with the average density in natural rural villages being 1.23 per 100 rat traps.M. musculuswas the predominant species in Hangzhou and Haiyan areas, whileR. tanezumiwas the predominant species in Quzhou city. The curve of rodent seasonal fluctuation showed a double peaked pattern. The highest rodent density was seen in Jiangshan city.Conclusion There are several rodent species in Zhejiang province that can transmit diseases, so it is important to strengthen the integrated surveillance to reduce the rodent density for the control of rodent-borne diseases.
