【摘要】 作者等于1989年3～10月对乌鲁木齐市及其近郊的鼠类和鼠害进行了调查。结果表明:乌鲁木齐市及近郊共有啮齿动物12种。近郊的平均捕获率为11.0％;市区的平均捕获率为21.1％。主要害鼠为小家鼠,灰仓鼠,褐家鼠和红尾砂土鼠。小家鼠和灰仓鼠为本调查区的优势种;红尾砂土鼠在市区总的数量虽然不高,但它却能长期在市区生存下来,而且破坏性很大;迁入鼠种——褐家鼠在西郊和相邻的北郊分布较广,并在继续扩散,在部分外生境已开始取代红尾砂土鼠。此外文中还对主要害鼠所造成的危害、分布范围、密度及与疾病的关系等进行了报道和讨论。更多还原

【Abstract】 An investigation of rodents and rat harm was carried out in Urumqi and its environs from March to October, 1989. Results showed that there were 12 species of rodents in the surveyed area with average capture rates of 21.1% and 11.0% in the urban districts and environs respectively. Main harmful rats were house mouse Mus musculus, migratory hamster Cricetulus migratorius, which were dominant species in the area, and red-tailed jird Meriones erythrourus and norway rat Rettus norvegicus. Athough red-tailed jird was not so great in number in the urban districts, it survived well and did much harm. The introduced norway rat was widely distributed in the west and north suburbs. The distributions, densities and Harm degrees of the rodents and their relations with disease transmission were discussed in the paper.更多还原
