摘要
本文结合CA(cellular automata)和AR(auto-regression)提出模拟人口空间场属性变化的CA-AR模型,以1991～2006年成都市各区、县市的人口统计数据和成都市行政区划图为基础,将行政单元转化为单元网格,分别建立成都市主城区各单元格的CA-AR模型。结果显示,模拟结果的绝对误差和相对误差都较小,模拟精度较高,模型的显著性水平都比较高,说明CA-AR模型用于模拟人口空间场的人口数量变化是可行的。
CA-AR model was brought forward to simulate the attribute changes of population space field integrated CA and AR in this paper.District was transformed to grid unit and CA-AR model was established for main city zone grids in Chengdu city based on the census data 1991～2006 and district boundary map.The results showed that the absolute error and relative error of simulation re- sults were small and precision was very high.So it is feasible to simulate the population quantity changes for population space field...
