摘要:

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。

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.
