Digital Simulation of Population Density in China
中国人口密度数字模拟

Spatial distribution of population density is simulated on the ba sis of fusing remotely sensed data, meteorological data, soil data and statistical data by means of a grid-generation based model that is newly constructed in this paper. The result shows that the highest values of simu lated population density almost centralized in the triangle-zone, taking Beijing, Shanghai and Zhengzhou city as its vertexes, and in the Pe arl River Delta. In the meantime, the highest density triangle-zone te nds to be a pentagon taking Shanghai-Nanjing-Hangzhou urban agglomerat ion, Wuhan city, Xi'an city, Beijing-Tianjin-Tangshan urban agglomeration and Shenyang-Dalian urban agglomeration as its five vertexes. The hig hest density zone in the Pearl River Delta is expanding to its outer-ring.
