垃圾填埋场对鼠种分布及密度影响分析

Distribution and density of rats in rubbish field

目的调查大型垃圾填埋场、附近村庄和对照点鼠种群分布及密度消长的情况,研究垃圾填埋场对鼠类的影响。方法夹日法。结果鼠密度平均在3.5%以下,对照点高峰室内、外在春季,区域点室内高峰在春季,室外高峰在夏季;鼠种构成室内区域点以褐家鼠为主,对照点以小家鼠为主,室外区域点和对照点均以臭鼩鼱为主。结论垃圾填埋场对鼠种分布及季节消长均会产生很大的影响,但人为因素在鼠害的控制工作中更加重要。

Objective To study the distribution,population density and seasonal fluctuation of rat in large water- scale rubbish field, nearby village and on contrast spot. Methods Captured with mousetrap everyday. Results The aveage density of rat was under 3. 5%. The peak of rat density of contrast point was in spring and indoor field point was in spring,outdoor field point was in summer. The dominant species indoor was Rattus norvegicus in field point and Mus musculus in contrast point. Suncus murinus was the dominant species outdoor of either field point or contrast point. Conclusion Rubbish field could generate a great influence of the distribution, population density and seasonal fluctuation of rat, but human factor played more important role in four pests control.
