On Measuring Polycentricism of Population Distribution in Mountainous Cities：With Chongqing as a Case Study

摘要: 重庆城镇化率从2000年的35.6％提高到2010年的53.0％，并逐渐形成视觉意义上的多中心组团式结构，而目前对这一空间结构少有严格的定量分析．本文基于人口分布数据，运用线性模型、乘幂模型、Clark模型、Tanner‐Sherratt模型、Newling模型等模型验证山地城市的多中心结构．结果发现：重庆市2000年多中心性并不明显，但2010年多中心性开始凸显，形成以解放碑为中心，观音桥、沙坪坝、南坪、杨家坪为次中心的多中心结构；多中心结构中，解放碑仍具有很强的人口集聚作用；在次级中心中，观音桥受两江新区影响其人口集聚作用较强．总体上，满足人口空间分布假设，即人口密度受最邻近的中心或次级中心的影响．此外，模型结果显示，非参数模型的拟合度明显高于参数模型．
