Study on Spatial Distribution Pattern of Population Pressure in China Based on GIS: Example of Application of Spatial Data Mining in Demography
基于GIS的人口压力空间分布模式研究——空间数据挖掘在人口学领域应用的实例

The population pressure indexes were proposed and an evaluation on the population pressure in China was made by employing the principal component analysis. Provinces and cities were classified into different categories according to the population pressure indexes. Based on this, adopting spatial autocorrelation analyzing method used in spatial data mining, the author analyzed the spatial distributirn pattern of population pressure. The study indicated that the population pressure in China decreased from west to east. The spatial distribution of population pressure demonstrated a spatial clustering pattern. There was a low-low spatial correlation in the area of Beijing, Tianjin, Zhejiang, Fujian, Shandong and the surrounding provinces, and a high-high spatial correlation in the area of Shanxi, Gansu, Qinghai, Sichuan, Chongqing and the surrounding provinces. This kind of spatial distribution pattern should be paid much attention to by the decislon-making department of the government.
