摘要: 以中国大陆区县级历史人口数据为基础, 研究人口总量和人口增长率的时间序列变化规律, 并综合运用阻滞模型、 指数模型、 对数模型、 线性模型等拟合方法, 得到相当精度的拟合预测模型, 获得了经验证较可靠的中国大陆未来区县级总人口预测结果。 同时, 以2020年预测人口为例, 定量分析了2010—2020年人口空间分布格局, 各区县未来人口增减变化情况, 其能够较准确的表达未来人口空间分布。 本研究旨在为地震风险评估对人口在时间变化和空间分布上的未来预测需求提供可靠数据。

Abstract: Based on the historical population data on the scale of county in mainland China, two kinds of time series of historical total population and growth rate of population were studied. The fitting models such as logistic, exponential, logarithmic and linear models were comprehensively used, good accuracy of the fitting have been obtained. It is proved that the reliable total population projection can be achieved for each counties of mainland China. Population projection in 2020 has been taken as an example, the spatial pattern of population distribution in 2010 and 2020 were quantitatively analyzed, and the changes of population size in each county of China main in 2010 to 2020 are illustrated in detail. It shows that the spatial distribution of population in future has been accurately expressed. Thus, it can provide reliable population data on spatial and temporal distribution for the future prediction of earthquake risk assessment.

Key words: Population projection, Spatial distribution of population, Earthquake risk assessment
