唐代前期陕北地区户口数据异常的环境社会释读——以坊、鄜、延三州为例

The Environmental and Social Interpretation of Abnormal Population Data in Northern Shaanxi in Early Tang Dynasty——Take Fang,Fu and Yanzhou as an Example

唐代的坊、鄜、延三州地处黄土高原,是历史时期农牧交错带研究的重要区域。史籍所载三州的户口数量明显异常,具体表现在户口分布和增长速率之上。在排除数据讹误可能性后,综合考虑地形地势和气候等环境因素,可以发现地理环境在很大程度上影响到了区域内部的人口分布。在社会层面上,军事形势变化和人口政策直接影响到人口的迁移和增长速率。从环境和社会层面综合释读历史时期的人口数据,能为历史时期农牧交错带的相关研究提供佐证。

The three states of Fang,Fu and Yan in Tang Dynasty are located on the loess plateau,and are the important areas for the study of the agro-pastoral zone in the historical period.The number of household registrations in the three prefectures contained in the historical records is obviously abnormal,which is specifically reflected in the distribution and growth rate of household registrations.After eliminating the possibility of data corruption and considering the environmental factors such as topography and climate,it can be found that the geographical environment has greatly affected the population distribution within the region.At the social level,changes in the military situation and population policies directly affect the rate of population migration and growth.The comprehensive interpretation of historical population data from the environmental and social levels can provide corroboration for the related research on the agro-pastoral zone in the historical period.
