摘要
新型城镇化作为中国当前一种宏大的多层次城镇空间组织现象,引发了社会的普遍关注。本文在宏观、中观两个层次上,分别运用多情景预测分析、综合分析等方法,构建"区域-城市群"两层级分析框架,系统阐述该框架下不同地区的新型城镇化发展的态势和模式,并对新型城镇化空间发展格局的优化问题进行了初步思考。研究表明:中国区域梯度格局基本保持稳定,逐步面向区域均衡方向发展;东部、东北、中部、西部四大区域在人口流动方面的梯度格局显著,在发展趋势中基本保持稳定,但中西部地区在一系列政策支持下的后发追赶态势逐步显现。中国的城市群均呈现明显的地域性特征,整体而言,由东向西城市群的分布密度依次降低、发展规模逐渐减小、发展水平不断下降;从规模体系和空间分布两个维度识别出强核多中心、多核分散、极核集中三种城市群类型,每种类型呈现出不同的空间发展模式和区域分布特征,进而突显出针对不同类型的城市群实施差异化政策的必要性。
On the macro-leveland meso-level, this article builds an analysis framework of Region-Urban agglomeration（RU） on the method of more situation forecast analysis and comprehensive analysis. Under the analysis framework,the paper analyzes the spatial development trend and pattern of new urbanization. Furthermore, it also conducts a preliminary thinking about the optimization strategies of new urbanization. The results show that：there is a significant gradient pattern of population flow of east, northwest, central and west china, but with the support of a series of policy, the central and west china have been pursuing the east china. Urban agglomeration in China presents obvious regional features. Overall, distribution density, development scale and level of urban agglomerations gradually decrease from east to west. The paper identifies three types of urban agglomerations on two dimensions of the scale system and spatial distribution. Each type presents its own space development pattern and regional distribution characteristics, and then it is necessary for us to implement different development policy to support different types of urban agglomerations.
