摘　　要：对内蒙古7个民族18个人群5项舌运动类型(卷舌、叠舌、翻舌、尖舌、三叶舌)调查结果进行了聚类分析与主成分分析.聚类分析结果显示18个人群可分为5个组:中西部区蒙汉混合组、呼伦贝尔组中部与东部区多民族混合组、西部区汉族组、西部区蒙古族组,表现出地域特点、民族特点、民族内部的多元性以及民族间出现一定程度融合的特点.主成分分析中PC 表示尖舌与翻舌,PC 表示叠舌,PC 表示三叶舌与卷舌.在PC 、PC 组成的坐标系中,18个人群分布具有极明显的地域特点.生活在同一地区的人群位点接近.在PC 、PC 组成的坐标系中,可以发现多数东部区人群具有较高的三叶舌率和(或)卷舌率,多数西部区人群三叶舌率和(或)卷舌率较低.Cluster analysis and principal component analysis were made on data of five tongue moving types of 18 populations from seven nationalities in Inner Mongolia. Cluster analysis showed that these 18 populations could be divided into five groups: Mongol and Han nationalities mixed group in mid-west area, Hulun Buir group, multinaionalities mixed group in mid-east area, Han nationality group in west and Mongol nationality in west. The tongue moving types showed some distinguishing features of the region and the nationality. The diversities in one nationality and mixer between nationalities could be seen from the results.In the principal component analysis, PCⅠ stood for pointed and twisting tongue, PCⅡ folding tongue and PCⅢ clover-leaf and rolling tongue. In the coordinate of PCⅠ and PCⅡ, a extremely evident features of the region could be found in the distribution of 18 populations. Dots representing populations on the same region were located closely. In coordinate of PCⅠ and PCⅢ, populations in the east mostly had high frequencies of clover-leaf tongue and (or) rolling tongue, but populations in the west mostly had low frequencies of them.
