成都市人口密度分布差异的影响因素

成都市可分为中心城区、近城区、近郊区和远郊区4个区域。5年来成都市人口向近城区集聚程度高于近郊区，人口密度差异逐步增大，主要表现为中心城区人口高度聚集。Clark密度模型的模拟效果表明：成都市人口向中心地区聚集，离开市中心点不同距离的区域人口密度差异逐渐增大。成都市人口密度分布的差异主要受自然地理环境、经济社会发展水平、经济社会政策和政府行为因素影响。

On Chengdu's Population Density Distribution and the Influencing Factors

The City of Chengdu is usually divided into 4 district circles: the city center,the urban circle,the near suburban circle and the far suburban circle.In the past 5 years,more population has moved into the urban circle of the city than the one in the suburban circles,leading to an increasing unbalance of population density of the city.A simulating test by Clark density has confirmed the heavier aggregation of population in the urban area of the city and the density gap between the circles has increased gradu...
