摘要
针对驱动力对人口城镇化的空间变异特征分析不足的问题,该文以长江经济带市域为基本单元,借助社会经济数据,引入自然环境数据,建立了经济、社会、环境和土地因子的测度指标体系。运用探索性空间数据分析和地理加权回归模型,定量分析人口城镇化的空间格局、动力因子以及空间分异性。结果表明:人口城镇化水平区域间差异显著,呈现明显的空间集聚性,形成了"圈层集中-东西对立-中心联动-梯度明显"的分布格局。动力因子对各地区人口城镇化的影响呈现明显的空间异质性,环境因子和经济因子是长江经济带人口城镇化发展的主要影响因素,动力因子的影响程度和变化趋势能够客观的反映出区域经济发展、环境状况、社会发展和土地现状对城镇化发展在空间上的影响。
According to the lack of spatial variability analysis of population urbanization under the driving force,an evaluation index system was established in this paper.Based on the socio-economic and environment data,this evaluation index system includes four types of driving forces：economy,society,environment and land,which are using cities as basic units.Combining with ESDA and GWR methods,spatial patterns,driving factors and the spatial heterogeneity of population urbanization quantitatively were analyzed.The results indicated that the differences between cities＇ population urbanization were significant,the spatial agglomeration was very obvious and a spatial patterns were discovered,which were concentrated layers,East-West dichotomy,center linkage,evident gradient.Meanwhile,the results presented significant spatial heterogeneity of the effect of driving factors,and environment and economic factors were the main driving factors for the urbanization development of the Yangtze River economic belt.Moreover,the impact＇s degree and trends of the driving factors could objectively reflect the spatial impacts of economic,social,environment and land development on urbanization.
