| 摘 要： | 地学研究中使用的人口数据主要包括:现代人口调查数据、人口预测数据和历史人口统计数据。不同来源的人口数据,具有不同的特点。在使用中,必须关注人口数据本身蕴含的属性特征、空间特征和时间特征。就属性特征而言,需要注意人口统计指标含义的差异、统计口径的差异、城镇建制标准的变化问题;就空间特征而言,需要注意人口统计单元界线的模糊与争议、行政区划的调整与变更、研究区与人口统计单元不一致问题;就时间特征而言,需要注意人口数据的统计时点。在使用人口数据,特别是不同来源、不同时期的人口数据时,应该根据人口本来的属性对不同统计口径和不同统计方法的人口数据进行重新归类和统计;根据行政区划调整情况进行人口数据的再统计,或开展人口数据的空间化;根据人口数据准确的时间特征进行比较,或采用相应的人口预测方法加以推断和预测,从而实现人口数据的整合,以增强人口数据的时空可比性。

| Abstract: | In recent years,quality and uncertainty of population data have attracted a mass of attention,but more attention was paid to uncertainty of population data itself and less to uncertainty that was results from inaccurate using.Population data that used in geo-science mainly includes modern population investigation data,population forecast data and historical population data.Different population data that come from different sources have different characters.When population data are used,attribute character,spatial character and temporal character of population data should be paid attention.As to attribute character,the main attention should pay to the differences of statistical indexes of population data,the differences of population data of statistical resources and the change of standard of setting up town or city.As to spatial character,the main attention should pay to illegibility and uncertainty of administrative borderline,adjustment and change of administrative regions and the difference between the study area and the statistical unit of population data.As to temporal character,the statistical time of population data should be cared for.When population data with different sources and time are used,they should be integrated firstly.The main measures include: reclassifying and recounting data based on different statistical indexes and standards of population data;recounting data based on adjustment of administrative regions,or spatializing population data;forecasting or calculating population data for special time based on accurate temporal character of population. |
