摘　　要：区域可持续发展理念已被社会各界所接收,并逐步深入到社会发展计划及区域政策制定中。以区域差异分析为基础的区域格局优化是促进区域发展的核心内容。从经济发展、资源利用、环境保护、人口与公共服务和科技创新等5个方面选取23个指标,构建其监测评估指标体系综合分析长江中游城市群综合发展水平时空格局演变,有助于认清长江中游城市群综合发展格局形成的过程,出现的问题及产生的原因,从而制定相应的区域调控政策,这对于促进长江中游城市群内部区域之间协调发展及推进中部崛起战略具有重要的现实意义。基于2005年和2011年长江中游城市群37个地级市的统计数据,借助SPSS、GIS软件,采用全局主成分分析法评价分析其综合发展水平及时空分异,并对其成因进行分析。结果表明:区域综合发展分值有所提升,但增长潜力仍然很大;发展水平差异显著,且两极分化趋势明显;整体呈现出以武汉和长沙为中心,以南昌、合肥为副中心发展格局,但中心城市带动作用较弱,制约各城市群发展的因素各异。因此,未来长江中游城市群应努力提升区域经济发展总量的同时,转变经济产业结构,加强企业创新能力,寻求新的经济增长点。与此同时,应加大基础设施尤其是道路交通的投资强度;充分利用已有的地理区位及资源、科技人才优势发展第二、三产业,提高经济发展中资源的利用效率,降低能耗,保护环境;除此之外,还应加强区域宏观调控,注重城乡统筹发展,协调、平衡区域内部均衡发展,缩小区域之间及内部差异,促进技术转移和优势互补。The concept of regional sustainable development has been widely accepted by all sectors of society and been embedded into the establishment of regional development strategies as well as social development plans.Optimizing land development patterns,which is usually based on regional difference analysis,is the core of promoting regional development.Spatio-temporal differentiation of comprehensive development level of middle reaches of Yangtze River was studied in this paper from five aspects,economic,resource utilization,environment protection,social service and population,and scientific and technological innovation.This is helpful to recognize the forming process of comprehensive development pattern,the potential problems and their causes,and thereby corresponding regional regulatory policies can be made by government.This is of great theoretical and practical significance to promote harmonious development among sub regions in middle reaches of Yangtze River and in turn to propel the rising of central China.Based on the statistical data of 37 prefecture-level cities of middle reaches of Yangtze River in 2005 and 2011,supported by SPSS and GIS software,this paper assesses the comprehensive development level of the study area by means of generalized principal component analysis （GPCA）,characterizes its spatio-temporal differentiation pattern,and then analyzes the causes.Results show that：（1） comprehensive scores of the region have increased while there is still great potential for further improvement; （2） the differences of development levels are striking and the trend of polarization are significant; and （3） the pattern of Wuhan and Changsha as center and Nanchang as well as Hefei as vice center has formed,but the influences of radiation generated by core cities are relatively weak,and different factors restrict different urban agglomerations.Geographical conditions,location and transportation as well as human capital and education are three main factors influenced the Yangtze River metropolitan a
