摘　　要：四川省独特的自然地理环境孕育了数目众多的啮齿动物,通过对近60年有关啮齿动物的著作及研究文献的检索整理和归纳分析,得出四川省境内分布的啮齿动物共2目12科41属101种又105亚种,其中兔形目18种,啮齿目83种。区系上属东洋界61种,古北界34种,广布种6种;分布型上属古北型13种,东北-华北型1种,高地型20种,喜马拉雅-横断山区型27种,云贵高原型2种,南中国型8种,东洋型24种,不易归类型6种。共划分为五个动物地理省,啮齿动物种类数量上盆地西缘山地省>川西南高山峡谷省>川西北高山高原省>盆中平原丘陵低山省>盆地东北缘山地省。中高山森林草甸啮齿动物种类最为丰富,海拔分布以2 000-2 600m种数最多。Sichuan Province with its large area and unique natural environment has a high diversity of rodent species.Based on nearly 60 years of monographs,published literature studies and comprehensive analyses on rodents,the main results are as follows:in Sichuan Province,southwestern China,there is a total of 101 species and 105 subspecies of rodents belonging to 2 orders,12 families,and 41 genera.Regarding the fauna,61 species are found in the Oriental realm,34 in the Palearctic realm,and 6 are widely distributed.Based on their distribution,13 species are of the Palearctic type,1 of the Northeast-North China type,20 of the Alpine type,27 of the Himalayan-Hengduan Mountain type,2 of the Yunnan-Kweichow Plateau type,8 of the southern China type,24 of the Oriental type,and 6 of the Inconvenience Divide type.Furthermore,the rodent population can be divided into five geographical regions:Sichuan Basin West Border Mountain,Southwest Sichuan High Mountain and Deep Valley,Northwest Sichuan High Plateau,Sichuan Basin Northeast Border Mountain,and Sichuan Basin Southeast Mountain provinces.Moreover,owing to the mid-to high-altitude forest growing at 2 000-2 600 m,there are more rodent species distributed here than at any other level,and the forest habitat is the most suitable environment for rodents.
