摘要: 1995年9月,作者对安徽淮北萧县的皇藏峪进行了啮齿类区系调查。由于该峪面积较小,景观较单纯,本次调查将该峪划分为针叶林、落叶阔叶林、峪内农田及荒草地3个地理景观区,共捕鼠119只,计7种。以峪内农田荒草地鼠密度最高,为19.83%,黑线姬鼠为优势种,占捕鼠总数的58.34%;落叶阔叶林区鼠密度为13.53%,社鼠为优势种,占7298%;针叶林区鼠密度最低,为7.53%,中华姬鼠为优势种,占61.90%。社鼠和中华姬鼠为我省淮北地区新纪录。从捕获的7种鼠看,属东洋界种1种;广布种3种;古北界种3种。从该区啮齿类区系组成和优势种看,应属古北界,但亦存在着明显的过渡色彩。

Abstract: The authors made an investigation on fauna distribution in Huangcang Valley, XiaoCounty Huaibei Anhui Province'in Sept.1995.The authors divided this small geographically monotonousvalley into three sections as their landscape variations: conifer tree area, decidous-broadleaf tree area andcultivated & uncultivated land area.A total number of 119 rodent specimens in 7 species were caught.The rodent desity was 19.83% in the cultivated & uncultivated land-the highest among the threeareas.Apoemu agrarius, being the dominate species, 58.34% ocupation in rodent population.The rodent density in decidous-broadleaf tree area was 13.53% and 72.98% of which was ocupied by Rattusnivirenter.The lowest density was found in conifer tree area.It was only 7.53% with dominant Apodemus draco taking 61.90% ocupation.The Rattus niviwnter & Apodemus draco were the first time tohave been found in Huaibei Anhui Province.Of all the 7 species, one belongs to Oriental realm species;three are widely spread species; three are Palaearctic species.The authors consider that the fauna distribution in Huangcang Valley falls into Palaearctic realm according to total composition and dominant species,however there is obvious color of transition.
