摘要目的提出一个描述中国姓氏分布特征的指标，并探讨其对人口结构和动态的影响。资料与方法姓氏数据来自全国公民身份信息中心，2007年登记的12.8亿中国公民，不包括香港、澳门和台湾。基于拉伸指数截尾幂律分布的交叉点，提出了拉伸指数分布覆盖率（CRSED）指标，其中拉伸指数项和幂律项的贡献相等.我们使用多维标度技术来证明一个县的相似性对其他的CRSED的依赖。结果362个地市的农村社会经济发展不均衡。这一指数的一致性体现在三个行政级别的社会经济发展指数之间的强正相关。这一新的指数与稀有姓氏的比例有很强的负相关性。具有相似CRSED的县往往在行政地图上彼此相邻，导致几个不同的地区，每个地区都有相似的地形特征或历史迁移。CRSEDs较低的县与其他县的差异较大，而CRSEDs较高的县与其他县的差异较大。讨论CRSEDs较高的地区的种群动态更可能是由迁移运动主导的，CRSEDs较低的地区的主导进化力量可以归因于漂移和突变。
Abstract Objective We propose an index to characterize the key feature of Chinese surname distributions and investigate its implications for population structure and dynamics. Materials and methods The surname dataset was obtained from the National Citizen Identity Information Center, which contains 1.28 billion Chinese citizens enrolled in 2007, excluding those of Hong Kong, Macao, and Taiwan. An index, the coverage ratio of stretched exponential distribution (CRSED), is proposed based on the crossover point of stretched exponential truncated power‐law distribution, where the stretched exponential term and the power‐law term contribute equally. We use multidimensional scaling technique to demonstrate the dependence of the similarity of one prefecture to the others on the CRSED. Results The CRSEDs of 362 prefectures exhibit an uneven distribution. The consistency of this index is evident by strong positive correlations of CRSEDs at the three administrative levels. This new index has a strong negative correlation with the proportion of the rare surnames. The prefectures with similar CRSEDs tend to adjoin each other on the administrative map, resulting in several distinct regions, each of which shares similar terrain features or historical migrations. The prefectures with lower CRSEDs are more dissimilar to the other prefectures, while the ones with higher CRSEDs are more similar to the others. Discussion The population dynamics of the prefectures with higher CRSEDs are more likely dominated by migratory movements, the dominant evolutionary forces of the prefectures with lower CRSEDs can be attributed to drift and mutation.
