【摘要】：人口发展功能分区研究是解决我国宏观与区域人口布局的重大课题。已有的研究多以行政区划为基本单元,研究尺度涉及国家级、省级以及市县级,较少涉及城市圈的人口功能分区。以武汉城市圈为研究对象,以传统的基于行政区划的人口发展功能区为参比,在对统计型人口数据进行空间化的基础上,以人口数据与地理数据的叠加分析结果为基本依据,通过建立人口与耕地、水体和高程的决策树,探索一种全新的人口功能分区路径,并对两种人口功能分区的结果进行对比分析。研究表明:和传统的基于行政区划的人口发展功能分区结果相比,基于人口数据空间化技术的人口发展功能分区结果在总体上与前者吻合,同时具有如下优势:一是在分区方法上摈弃了诸多的指标计算,二是分区的精度得到了加强,三是更加有利于统计数据与资源环境数据的耦合分析。对今后特定区域的人口发展功能分区研究具有一定的借鉴意义,为实现更加客观、更有利于应用的规划方法提供思路。
[Abstract]:The study on functional zoning of population development is an important task to solve the macro and regional population distribution in China. Most of the existing studies take administrative division as the basic unit. The scale of the research involves the national level, provincial level and city and county level, and less involves the population functional zoning of the urban circle. Taking Wuhan urban circle as the research object, taking the traditional population development function area based on the administrative division as the reference, on the basis of the spatialization of the statistical population data, and taking the superposition analysis result of the population data and geographical data as the basic basis, By establishing the decision tree of population and cultivated land, water body and elevation, a new path of population function zoning is explored, and the results of two kinds of population function zoning are compared and analyzed. The results show that: compared with the traditional results of population development function zoning based on administrative division, the results of population development function zoning based on population data spatial technology are consistent with the former on the whole. At the same time, it has the following advantages: first, many index calculations are abandoned in the partition method; second, the accuracy of the partition is strengthened; third, the coupling analysis between statistical data and resource and environment data is more advantageous. It has some reference significance for the future study on the functional zoning of population development in a specific region, and provides a way of thinking for realizing more objective and more useful planning methods.
