THE FORECAST ON THE POPULATION SPATIAL DISTRIBUTION PATTERN BASED ON THE GRAY THEORY
用灰色理论预测各省市人口总量，结合GIS空间自相关分析，发现2005-2020年北京、上海等地区人口密度与周边保持高-高相关，西部和东北部为低-低相关，广东为负相关，2014年人口分布将有重大变化。
The gross population of each province and city is predicted by gray theory and the population spatial distribution pattern is forecasted by employing spatial autocorrelation theory of GIS.The study indicates that from 2005 to 2020,the population density of some quarters like Beijing,Tianjin,Jiangsu,Shanghai will remain a high-high correlation with the surrounding areas' population density.In those areas population concentration has emerged.The population density of some quarters in the west and north east will remain a low-low correlation with the surrounding areas' population density.Guangdong province is negatively correlated with its surrounding areas,thus it is only a concentration point. 2014 will witness many great changes in population distribution.
