- 摘要：
探究城市人口空间集聚的变化特征是推进其高效能治理的关键，对人口优化布局、基础设施配置等具有参考意义。基于街区层面的人口普查数据，综合运用人口集聚度及其增长指数等指标对兰州城市人口的空间集聚变化进行解析。结果表明：3 个普查年的人口密度均表现出“东高西低、北高南低”的空间格局，在主城 4 区与河谷盆地两个尺度上呈现典型的“中心—外围”格局；城市人口发生了由“双峰体”向其中间地带集聚的现象。各类人口集聚区的数量与范围变化差异较大，呈现以城关旧城和西固旧城为双中心的圈层结构。人口集聚度增长变化也表现出“东高西低、北高南低”的空间格局，4 类街区在河谷盆地内外的分布差异较大。城市人口的空间集聚主要受自然地理环境、户籍制度改革、公共政策引导、交通设施建设和经济社会发展等因素的综合影响。 - 关键词：

It has reference significance for population optimization layout, infrastructure configuration. Based on the population census data at the district level, comprehensive using several indicators such as population agglomeration degree and its growth index, the paper analyzed the spatial agglomeration change of Lanzhou city population. The results showed that the population density in the three census years presents a spatial pattern of “high in the east and low in the west, high in the north and low in the south”, presenting a typical “center periphery” pattern at the scales of the four downtown of city areas and the river valley basin. The city population has a phenomenon of agglomeration from two peak-body to the middle zone. The number and scope of various population gathering areas vary greatly, showing a hierarchical structure with Chengguan old city and Xigu old city as the dual centers. The growth of population agglomeration also shows a spatial pattern of “high in the east and low in the west, high in the north and low in the south”, with significant differences in the distribution of the four types of blocks inside and outside the river valley basin. The spatial agglomeration of city population is mainly influenced by a combination of factors such as natural geographical environment, registered residence system reform, public policy guidance, transportation infrastructure construction, and economic and social development.
