摘　　要：在广泛搜集、系统整理资料基础上,建立数据库,运用GIS(Geographic Information System)技术分析了中国画眉科鸟类的地理分布格局,并进行鸟类分布相似率比较及以画眉科鸟类为对象进一步探讨中国动物地理区划单元之间的相互关系。结果显示中国画眉科鸟类130种,分属26属,水平分布上具不均性,在动物地理区上表现为西南山地亚区分布最多(114种),其次是滇南山地亚区(94种);有2个物种多样性分布中心,即横断山中心和滇南山地中心。对于鸟类分布相似率,古北界各区、亚区之间的相似率波动较大;而东洋界各区、亚区之间相似率波动较小。中国各动物地理亚区相互关系聚类结果基本为古北界、东洋界各处一个大枝。Database was constructed based on extensive and systematic data collection and collating, then distribution of babblers in China, distribution similarity and relationships among geographic units were analyzed by geographic information system （GIS）. The results suggested that there were 130 species of Chinese babblers belong to 26 genera, and showing an uneven horizontal distribution. Most of the Species were distributed in Southwest Mountain Subregion （114 species）, fol- lowed by South Yunnan Mountain Subregion （94 species）. Hengduan Mountains and South Yunnan Mountains were the dis- tribution centers of species diversity. The distribution similarities were different in Palaearctic realm compared to Oriental realm. In general, the zoogeographical subregions in China can be divided into two big branches ： Palaearctic realm and Ori- ental realm.
