【摘要】 随着经济全球化和区域经济一体化的发展,以核心大城市带动的城市群战略已经逐步成为全球发展的热点问题。中原城市群是我国中部地区经济发展新增长极、重要的交通枢纽,是先进制造业和现代服务业基地、内陆地区双向开放新高地。研究中原城市群城市综合发展水平,不仅有助于了解中原城市群的发展特点、发展规律、现阶段发展水平等,也为相关部门规划合理有序的城市体系提供决策参考,是促进中部崛起战略推进的需要。本文以中原城市群为研究区,在充分了解中原城市群发展现状的基础上,构建科学合理的城市发展水平评价指标体系,选取合适的指标,采用Landsat遥感数据、DMSP/OLS夜间灯光数据、NPP-VIIRS夜间灯光数据和统计年鉴数据提取所需指标信息,运用主成分分析法对2006年、2011年和2016年中原城市群各城市发展水平进行评价,并对评价结果从时间、空间、时空格局演变和影响因素四个角度进行分析,以期全面揭示中原城市群城市综合发展水平变化特征,为相关部门进行城市发展规划等工作提供参考。得到的主要结论如下:(1)从时间角度看,中原城市群城市综合发展水平总体表现为逐年增长的趋势,且增长速度具有阶段性。根据城市发展水平增长速度可将城市分为两类:增长速度先快后慢的城市,如平顶山、济源、长治、晋城;增长速度先慢后快的城市,如郑州、开封、洛阳、安阳等大部分城市。以中原城市群2006-2016年整体增长速度为基准,可以将城市分为比中原城市群整体增长速度快和慢的两类城市,分类后显示大部分城市增长速度在城市群整体水平以下。(2)从空间角度看,根据城市综合发展水平评价得分特点将中原城市群城市划分为5个等级并进行空间化,发现等级城市个数变化不规律,空间分区变化显著,且南北城市发展差异有扩大趋势,及各城市之间发展存在不平衡性。郑州、洛阳、南阳综合发展水平一直居于第一等级,而鹤壁、济源、漯河等城市则长期处于第五等级,南北差异较大;其他城市均存在不同程度的变化,表现出中原城市群内部发展的动态性。城市发展等级变化的结果是,到2016年第一等级城市全部在黄河以南地区,综合发展水平较高的城市在黄河以南地区所占比重越来越高。(3)从时空格局演变角度看,2006年-2011年,城市综合发展水平从较低等级上升到较高等级的城市多集中在中原城市群中西部地区。2011年-2016年,城市综合发展水平从较低等级上升到较高等级的城市多集中在中原城市群东部地区。2006年-2016年,综合考虑城市综合发展水平等级变化和空间分布,发现综合发展水平较好的城市和等级上升的城市在空间上基本沿石武客运专线和徐兰客运专线分布;在郑渝高速铁路、郑合客运专线、郑太客运专线和郑济高速铁路沿线上的城市则多为综合发展水平一般和等级降低的城市;而不在“米”字形交通网上的城市都是发展程度较低和等级降低的城市。(4)从影响城市发展水平的因素角度看,地方财政收入、地区生产总值、建成区面积、社会资产投资、城镇人口是造成城市发展水平高低变化和空间差异的主要因素,而人均绿地面积、娱乐教育文化消费支出占GDP比重、环保投资占GDP比重等指标对城市综合发展水平的影响极其有限。更多还原

【Abstract】 With the development of economic globalization and regional economic integration,the strategy of urban agglomeration driven by core cities has gradually become a hot issue in global development.The Zhongyuan Urban agglomeration is the new growth pole of economic development in the central part of China,the important transportation hub is the base of advanced manufacturing industry and modern service industry,and the inland areas open new highlands in both directions.To study the comprehensive development level of Zhongyuan urban agglomeration is not only helpful to understand the development characteristics,laws and the level,but also provides a reference for the relevant departments to plan a rational and orderly urban system.And it is the need to promote the strategic promotion of the rise of central China.This paper takes Zhongyuan urban agglomeration as the research area,on the basis of fully understanding the present development situation of Zhongyuan Urban agglomeration,then constructs a scientific and reasonable evaluation index system of urban development level,and selects the appropriate index.Using Landsat remote sensing data,DMSP / OLS night lighting data,NPP-VIIRS night lighting data and statistical yearbook data to extract the index information needed.Using the method of principal component analysis(PCA)to evaluate the development level of Zhongyuan urban agglomeration and the cities in 2006,2011 and 2016.In order to reveal the characteristics of the comprehensive development level of Zhongyuan urban agglomeration,the evaluation results are analyzed from four angles of time,space,space-time synthesis and principal component,and provide reference for relevant departments to carry out urban development planning and other works.The main conclusions are as follows:(1)From the point of view of time,the level of comprehensive development of Zhongyuan urban agglomeration shows a trend of increasing year by year,and the growth rate is phased.Cities can be divided into two categories according to the growth rate of urban development level:1.Cities that first grow faster then slower,such as Pingding Shan,Jiyuan,Changzhi and Jincheng.2.Cities that first grow slower then faster,such as Zhengzhou,Kaifeng,Luoyang,Anyang,and the most of cities.Cities can be divided into two categories based on the growth rate of Zhongyuanurban agglomeration from 2006 to 2016: cities that grow faster than the overall of Zhongyuan urban agglomeration,and the cities that grow slower than the overall of Zhongyuan urban agglomeration.It is found that the growth rate of most cities is below the overall level of urban agglomeration.(2)From the point of view of space,The cities can be divided into five grades according to the evaluation score characteristics.Spatialization the results,it is found that the number of hierarchical cities changes irregularly,the spatial zoning changes significantly,and the difference between the north and the south is great.And the difference of urban development between north and south has a tendency to expand.The comprehensive development level of Zhengzhou,Luoyang and Nanyang has been in the first grade,while Hebi,Jiyuan,Luohe have been in the 5th grade for a long time.Other cities have varying degrees of change,shows the dynamic nature in the development of urban agglomerations,and the imbalance between cities.As a result,the first class of cities was all in the south of the Yellow River by 2016.More and more cities with higher level of comprehensive development distributed in the south of the Yellow River.(3)From the point of view of space-time comprehensive development,The urban comprehensive development level rises from the lower level to the higher level,most of them are concentrated in the central and western regions of Zhongyuan Urban agglomeration in the year of 2006-2011.The urban comprehensive development level rises from the lower level to the higher level,most of the cities are concentrated in the eastern part of Zhongyuan Urban agglomeration in the year of 2011-2016.In the year of 2006-2016,considering the spatial distribution change and the level of urban comprehensive development,it is found that the cities with higher level and higher grades are basically distributed along the Shiwu passenger dedicated Line and the Xulan passenger dedicated Line in space.The cities with general level and cities with lower grades are mostly distributed along the lines of Zhengyu High Speed Railway,Zhenghe passenger dedicated Line,Zhengtai passenger dedicated Line and Zhengji High Speed Railway.The cities that are not on the "mi" traffic network are the cities with lower level and lower grade.(4)From the point of view of principal components,local fiscal revenue,regional gross domestic product,area of built-up areas,investment in social assets,urban population are the main factor that causes the change of the level of urban development and the spatial difference.While,the green space area of per capita,theexpenditure of entertainment,education and culture in GDP and the proportion of environmental protection investment in GDP have a very limited influence on the level of urban comprehensive development.更多还原
