| 摘要: |
| 为了解21世纪近10年南宁市城市人口空间结构的变化和发展，借助Geographic Information System （GIS）技术和SPSS统计分析软件，对2000年和2010年南宁市城市内部人口分布进行分析。结果表明，南宁市城市内部人口空间结构总体表现为集聚。2000年和2010年南宁市人口密度均以西乡塘街道办事处范围内最高，兴宁区内各街道人口密度增长较快；2000-2010年人口重心向西北移动约1.2 km；2000年人口密度函数和2010年人口密度函数分别以反函数模型和二次函数模型拟合最优。随着距市中心的距离增加，人口密度递减；在市中心附近具有较大的向心效应，带来周边邻近区域人口的增长。 |

| Abstract: |
| In order to understand the changes and development of the spatial structure of Nanning's urban population in the past 10 years in the 21st century, Geographic information system (GIS) technology and SPSS statistical analysis software were used to analyze the urban population distribution in Nanning in 2000 and 2010. The results showed that the overall spatial structure of Nanning's urban population was clustered. In 2000 and 2010, the population density of Nanning City was highest in the area of Xixiangtang Sub-district Office. The population density of each street in Xingning District increased rapidly. From 2000 to 2010, the population center of gravity moved about 1.2 km to the northwest. The population density function in 2000 and the 2010 population density function were best fitted with an inverse function model and a quadratic function model, respectively. As the distance from the city center increased, the population density decreased. It had a large centripetal effect near the center of the city, which brought about the increase of population in the surrounding areas. |
