目的　根据 1993～ 2 0 0 0年我省沿江西部地区鼠类调查结果 ,分析该地区鼠类种群结构 ,为有效防制鼠害提供依据。方法　选择农田和居民室内合适生境 ,采用夹夜法布放鼠夹 ,对捕获的鼠类进行种类鉴定 ,计算鼠种构成比和鼠密度 ,分析研究该地区鼠种结构和室内外优势鼠种。结果　农田鼠种包括黑线姬鼠、褐家鼠、东方田鼠 ,其构成比 (% )分别为 84 .33、9.6 7、5 .6 7,农田鼠密度为 9.0 2 % ,黑线姬鼠为该地区农田优势鼠种。室内鼠种包括褐家鼠、黄胸鼠、小家鼠、黑线姬鼠 ,其构成比 (% )分别为 5 3.2 2、35 .19、10 .73、0 .86 ,室内鼠密度为 11.5 2 % ,褐家鼠和黄胸鼠为该地区室内优势鼠种。结论　黑线姬鼠和褐家鼠、黄胸鼠分别为我省沿江西部地区农田和居民室内优势鼠种

Study on Characteristic of Rodents at the West Areas along Changjiang River in Anhui Provunce

Objective To analyze the data of rodents from 1993 to 2000 and understand characteristic of rodents at the west areas along the Changjiang river in Anhui province. Methods Night trapping method was used. Results Rodents at the farming areas was composed of 3 populations: that is, Apodemys agrarius, Microtus fortis and Rattus norvegicus; The composition rate of the rodents (%) were 84.33, 9.67, 5.67. The densities of the rodents at the farming areas was 9.02%. The community of the rodents at the populated areas was composed of 4 populations: Rattus norvegicus, Rattus flavipectus, Mus musculus and apodemys agrarius. The composition percentage of the rodents was 53.22%, 35.19%, 10.73%, 0.86% respectively. The density of the rodents at the populated areas was 11.52%. Conclusions The dominant rat at the farming areas was Apodemys agrarius and the dominant rats at the populated areas.were Rattus norvegicus and Rattus flavipectus.
