We collected available chorological data of birds and mammals in China and assigned faunal types. The 19 sub-regions of the zoogeographical regions of China were used as operative geographical units. Matrices of the geographical units using the species number of each faunal type were then constructed. Based on the matrices we clustered the geographical units using a hierarchical cluster analysis The results of the faunal divisions according to the cluster analysis were illustrated in a geographic information system (GIS). When 19 geographical units were clustered into two clusters, the boundary of the two clusters corresponded to that of the Palearctic and Indomalayan (Oriental) realms in the recent division of Chinese fauna. When the geographical units were clustered into eight clusters, the sub-region Southern Yunnan Hilly became an idiographic cluster. As a result, Southern Yunnan hilly should be regarded as a region rather than a sub-region at the same level as Southwest region, Central China region and South China region. The differences in the distribution patterns of birds and mammals among the units in the Indomalayan (Oriental) realm were more complicated than those in Palearctic realm. A few differences of the cluster analysis results based on the faunal types were found between the bird and mammal species. These differences might result from the different ecological and geographical distribution patterns of these two animal categories.
我们收集了中国鸟类和哺乳动物的现有分布数据，并划分了动物区系类型。中国动物地理区域的19个亚区域被用作实际地理单元。然后构建了使用每种动物区系类型物种数量的地理单元矩阵。基于这些矩阵，我们使用层次聚类分析对地理单元进行聚类。聚类分析得出的动物区系划分结果在地理信息系统（GIS）中展示。当19个地理单元聚为两类时，这两类的边界与中国动物区系最新划分中的古北界和东洋界的边界相对应。当地理单元聚为八类时，滇南山地亚区域成为一个独特的类。因此，滇南山地应被视为一个区域，而非与西南地区、华中地区和华南地区处于同一级别的亚区域。东洋界各单元之间鸟类和哺乳动物的分布模式差异比古北界更为复杂。基于动物区系类型的聚类分析结果在鸟类和哺乳动物物种之间存在一些差异。这些差异可能源于这两类动物不同的生态和地理分布模式。
