摘要
人口分布空间结构是城市空间结构的重要组成部分。为准确地模拟城市人口分布,清晰地反映城市人口分布格局,本文利用沈阳市第五次人口普查资料,采用网格计算方法空间化人口数据、地统计学的空间插值方法模拟人口分布。同时,用DEM模型方法识别城市人口分布格局,分析人口分布特征。结果是:沈阳城市内部人口分布具有较高的不均衡性和聚集性;城市人口密度分布不符合单核心圈层式范式,具有11个明显的人口分布核心;在城市中心区域,人口分布的区域化特征更为显著;人口分布主要受到相近的两个人口核心的影响。该研究同时表明中国市场经济体制背景下,城市人口分布特征具有较高的复杂性。对于城市人口分布规律及影响人口分布的动力机制,需进一步研究。
Population spatial structure is an important part in urban spatial structure. For more exact modeling population distribution condition and more expressly reflecting population spatial pattern in urban region ,with the fifth census data of Shenyang City, in this paper we spatialize population data by using grid calculating, model population distribution by using Geo-statistics,identify population pattern by using DEM models and analyze characters of population distribution. Main conclusions include： population distribution is unbalanced and accumulative in Shenyang City. There are 11 population distribution cores obviously instead of a monocentric pattern. Population distribution is more distinctly localized in the urban heartland. Population distribution is mainly affected by the two nearby population cores. This study implies that characters of population spatial distribution in Chinese cities take on several complexities under market economy system. So the rules and driving mechanism of population distribution in Chinese cities should be further studied. In the mean time, this paper thinks that statistics has shortcomings in studying population spatial distribution in urban region, geo-statistics and DEM models can heighten the theory and application levels of urban geography and population geography when they are applied in urban geography and population geography.
