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.

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。
