广东省湛江地区鼠形动物的演替

目的 探讨1950～2000年间湛江地区鼠形动物种群的动态变化。方法 收集整理湛江地区50年来的鼠疫监测资料，依次按年代进行鼠形动物的分类统计。结果 50年来共捕获家栖、野栖鼠形动物2目7属11种共计237831只，其中家栖鼠形动物2目3属4种157412只，以黄胸鼠为优势种，臭鼩鼱和褐家鼠为常见种；野栖鼠形动物2目7属8种共计80419只，以黄毛鼠和板齿鼠为优势种，海南屋顶鼠和臭鼩 鼱为常见种。结论 在城镇家栖鼠类中，褐家鼠已逐渐取代黄胸鼠的优势种群地位，但在农村家栖鼠类仍以黄胸鼠为主。野外生境黄毛鼠的数量在逐年减少，但板齿鼠的数量在逐年增加。

Dynamics of Murine-like-animal Community in Zhanjiang, Guangdong

Objective To study the dynamic changes of murine-like-animal community in Zhanjiang, Guangdong from 1950 to 2000. Methods Data of plague surveillance in Zhanjiang during the past 50 years were collected and sorted out to describe and analyze the changes of murine-like-animal community by year. Results A total of 237 831 murine-like-animals were captured and identified, including 11 species of three genera in two orders. Totally, 157 412 murine-like-animals in four species of three genera were captured domestically, with Rattus flavipectus as dominant species, accounting for 68% of the total, and Suncus murinus and Rattus norvegicus as common species, accounting for 25 % and 6 % , respectively. A total of 80 419 wild murine-like-animals in eight species of two genera in two orders were captured, with R. losea and Bandicoot indicia as dominant species, accounting for 80% and 18% of the total, respectively, and R. rattus hainanicus and Suncus murinus as common species. Conclusion In domestic rats of urban areas, R. flavipectus had been replaced by R. norvegicus which had become a dominant species there, but in rural areas, R. flavipectus was still the dominant species. Among wild rodents, population of R. losea reduced yearly, but that of Bandicota indica increased yearly.
