山东省鼠类调查报告

An Investigation of Rodents in Shandong Province.

1980～1981年,对属于山东省4个动物地理小区的8个县(市)进行了鼠类调查。根据调查结果,并结合文献和一些资料记载,对山东省啮齿动物的区系组成和地理分布进行了探讨。结果表明,黑线仓鼠为鲁北平原和鲁西南平原小区的优势种;黑线姬鼠常为其它小区特别是低洼地区的优势种;黑线仓鼠也常为其它小区旱地的优势种;大仓鼠和褐家鼠在某些年份、某些地区可成为优势种;大林姬鼠和社鼠仅在山区分布。黑家鼠、黄胸鼠、东方田鼠、棕色田鼠、岩松鼠和花鼠为我省的稀有种类。鲁南平原小区的丘陵花生田生境,鼠的种群密度竟高达71.4%和34.9%,其中黑线姬鼠高达49.9%和18.0%,可能与大型鹅卵石地堰这一生境有关。泰山顶的鼠类以黑线姬鼠占绝对优势(65.2%),且其数量稳定。

An investigation of rodents was carried out in 8 counties(cities)of 4 small animal geographic in Shandong province. 1980-1981. Based on the investigation results, references and data, we discussed the composition of fauna and their geographical distribution. The results are as follows: Cricetulus barabensis is the dominant species in LuBci plain and Luxinan plain; Apodemus agrarius in other regions, especial in Low lands; C. barabensis is always the dominant specices in the dry lands all over the province; C. triton and Rattus norvegicus in some areas in some years, A, peninaulae and R, confucinus are only distributed in mountainous areas. R. rattus and R. flavipectus, Microtus fortis, M. mandarianus, Sciurotamias davidianus and Tamias (Eutamias) sibiricus are the rare species. The population density of rodents reached 71.4% and 34.94% in the terraced peanut fields in hilly areas in Lunan plain, where A. agrarius was as high as 49.9% and 17.97% The high density may be related to the habitat-Large cobble weirs. A. agrarius is the dominant species,(65.20% ) on the top of Taishan and its population is stable.
