2006-2012年青岛市鼠密度监测结果分析

目的掌握青岛市鼠类种群构成季节消长和不同生境鼠密度情况，为制定鼠类防控方案提供科学依据。方法2006～2012年，选择青岛市城镇居民区（居民室内外）、特殊行业（厨房、库房）、农村住户（室内外）各一处，采用夹夜法进行鼠密度监测。结果2006-2012年青岛市共布夹47316次，捕鼠179只，平均鼠密度为0.39％。平均鼠密度，2006-2012年分别为0．57％、0．40％、0．23％、0．21％、0．42％、0．33％、0．59％；小家鼠、褐家鼠、黑线姬鼠分别为51.96％、45．81％、2．23％；鼠密度高峰在10月份，为0．49％；农村住户平均鼠密度最高为0．65％。结论2006～2012年鼠密度呈先下降、后上升趋势。

Analysis on the Rat Density Monitoring Results, Qingdao City

Objective To understand rat distribution,density and seasonal dynamics,so as to provide scientific basis for the control. Methods Rat density surveillance was conducted by night trapping method,with each surveillance site covering a residential area,a special industry and a natural rural village during 2006-2012. Results Over 47 316 mouse traps were arranged and 179 rats were captured in Qingdao city during 2006-2012. The average rat density was0.39%. The average rat densities were 0.57% ,0.40% ,0.23% ,0.21% ,0.42% ,0.33% and 0.59% during 2006 2012. Mus mus culus,rattus norvegicus and apodemus agrarius were dominant in Qingdao city, and their component ratio was 51.96%, 45.81 % ,and 2.23%. The peak of mean rat density was 0.49% in October. The density in villages was 0.63% ,which was the highest in different condition. Conclusion The rat density has high-low-high trend during 2006-2012.
