首都机场T3航站楼建设工程对其周边鼠种构成及鼠密度影响的研究

The influence of the Beijing Capital International Airport T3 terminal construction on circumjacent rodent composition and density

目的研究首都机场T3航站楼建设工程对其周边鼠种构成和鼠密度的影响,为鼠防工作提供依据。方法采用夹夜法,每月对首都机场T3航站楼施工工地及其周边区域的代表性生境进行调查。结果在T3航站楼工地共捕获鼠类3种102只,以小家鼠为优势种,占捕鼠总数的67.65%;黑线姬鼠和褐家鼠分别占21.57%和10.78%。2005-2008年T3航站楼工地鼠种构成差异有统计学意义(χ2=17.24,P=0.008),平均鼠密度逐年下降。结论T3航站楼建设导致的生态环境改变,引起鼠种构成和鼠密度的改变。重大建设项目应加强周边环境的鼠情监测,针对性的开展灭鼠工作。

Objective To study the influence of the Beijing Capital International Airport T3 terminal construction on circumjacent rodent composition and density, and provide the evidence for the rodents control. Methods The night trapping method was used to investigate the rodent composition and density in the representative environments around the T3 terminal construction sites monthly. Results There were 102 rats belonged to three species caught in T3 terminal construction sites. The dominant specie was Mus musculus, accounting for 67.65% of the total. Rattus norvegicus and Apodemus agrarius accounted for 21.57% and 10.78%, respectively. There was significant difference in the rodent composition from 2005 to 2008 （χ^2= 17.24, P= 0.008）, and the average rodent density reduced year after year. Conclusion The construction of T3 terminal led to the change of environment, resulting in change of rodent composition and its density. It should strengthen the surveillance of rodent for the important construction item around its peripheral environment and carry out thoroughly the killing of rodent.
