Abstract:Available geographical data of glires were collected to build their digital distribution map in the humid region of China based on habitat analysis supported by GIS.Using the equal-area grids of 6 470 km2 as geographical units,the distributional patterns of glires in the humid and semi-humid and semi-humid region of China were studied.There are 156 glires species in the study area,which are classified under 62 genera 12 families and 2 orders,accounting for 71.23% of the total glires species in whole China.Two areas harbor a high species richness in the study area,i.e Qinling Mountain in Shaanxi Province and the mountains in the south of Gansu Province,and Hengduan Mountains in the Yunnan and Sichuan Province.Relatively,the areas with low species richness locates in south of Hebei Province,Shandong,Henan and Jiangsu Province,the part of Anhui Province in the north side of Yangtze River and delta of Yangtze River,the areas of Hunan and Hubei along the Yangtze River,as well as the Sichuan basin.All the geographical units are divided into three groups according to the glires species component by hierarchical cluster analysis,i.e.north and south of the monsoon region dividing by the line from lower reaches of Yangtze River to the Qinling Mountain,and the semi-humid zone of the Qinghai-Tibet Plateau.
