中国人口密度数字模拟

运用基于格点生成法的人口密度空间分布模拟模型，通过运行净第一性生产力空间分布、数字高程、城市规模及其空间分布和交通基础设施空间分布等数据集，模拟了中国人口密度的空间分布规律。模拟结果表明，人口密度的最高值集中在北京、上海和郑州之间的三角区（BSZ）及珠江三角洲地区；同时，这个BSZ峰值三角区有发展为以上海－南京－杭州大都市密集区、武汉市、西安市、北京－天津－唐山大都市密集区和沈阳－大连大都市密集区为顶点的五角形峰值区的趋势，珠江三角洲峰值区也正在向外围地区扩展。

Digital Simulation of Population Density in China

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.
