Abstract:

Spatial distribution of population density is simulated on the basis 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 simulated population density almost centralized in the triangle-zone, taking Beijing, Shanghai and Zhengzhou city as its vertexes, and in the Pearl River Delta. In the meantime, the highest density triangle-zone tends to be a pentagon taking Shanghai-Nanjing- Hangzhou urban agglomeration, Wuhan city, Xi'an city, Beijing-Tianjin-Tangshan urban agglomeration and Shenyang-Dalian urban agglomeration as its five vertexes. The highest density zone in the Pearl River Delta is expanding to its outer-ring.
