【摘要】：随着经济发展和人口快速增长,城镇得以迅速膨胀。在人类历史发展过程中,城镇中心作用发挥如何,城镇空间结构布局如何,对国家和区域综合发展水平及发展速度都有重要影响。以长江经济带11省(市)为研究范围,将1999年、2004年、2009年和2014年确定为时间段面,对长江经济带不同空间尺度城镇体系状况进行研究,寻找其规律、差异和不足。论文研究的主要内容包括以下三个方面。(1)长江经济带城镇体系发展现状分析运用长江经济带2009年和2014年的相关数据,从总人口、人口密度、城镇常住人口、城镇化水平、城镇密度等5个方面对长江经济带整体、研究区东中西部、研究区11省(市)三个空间尺度城镇体系发展现状进行对比分析,探索其优势、差距与不足。(2)长江经济带城镇体系等级规模结构研究运用Zipf位序-规模分布法则及城市首位度指标,从长江经济带、东中西部三大地带两个空间尺度对长江经济带城镇等级-规模分形特征及首位城市进行研究,计算其分形维数值,在此基础上探求长江经济带城镇等级规模分布及其首位城市。(3)长江经济带城镇体系空间特征研究利用百度API接口开发的JAVA程序及Matlab软件距离(distance)函数量算出长江经济带110个城市相互间的直线距离;根据高德地图测量出110个城市之间驾车距离及驾车时长距离;运用分形理论,结合获取得到的城市间直线距离、交通距离和时间距离等数据,从长江经济带、东中西部三大地带两个空间尺度对研究区城镇体系空间分布特征及交通通达性进行研究;运用引力模型,基于各城市建成区常住人口、GDP及各城市间直线距离等数据对长江经济带各城市间的相互作用进行分析,同时从城镇体系中心位置定量测算及离散程度定量测算两方面对研究区城镇体系空间分布度量进行研究。基于研究结果,分别从研究区整体、东部地带、中部地带、西部地带不同地域空间对城镇体系结构提出相关优化建议。
[Abstract]:With economic development and rapid population growth, cities and towns can expand rapidly. In the course of the development of human history, how to play the central role of cities and towns, and how to layout the spatial structure of cities and towns have an important influence on the level and speed of comprehensive development of countries and regions. Taking 11 provinces (cities) of the Yangtze River Economic Belt as the research scope, this paper defines 1999, 2004, 2009 and 2014 as the time horizon, studies the different spatial scale urban system of the Yangtze River Economic Belt, and finds out its laws, differences and deficiencies. The main contents of this paper include the following three aspects: (1) the present situation of the development of the urban system in the Yangtze Economic Belt is analyzed by using the relevant data of the Yangtze Economic Belt in 2009 and 2014, from the total population, the population density, the urban resident population, the level of urbanization, and so on. From the five aspects of urban density, this paper makes a comparative analysis of the present situation of the development of three spatial scale urban systems in the Yangtze River economic belt, in the east, west and west of the research area, and in the 11 provinces (cities) in the research area, in order to explore its advantages. (2) the study on the hierarchical scale structure of the urban system in the Yangtze River economic belt, using the Zipf local-scale distribution rule and the first degree index of the city, from the Yangtze economic belt, The fractal characteristics of cities and towns of the Yangtze River economic belt and the first city are studied at two spatial scales in the three major zones of the east, west and west, and their fractal dimensions are calculated. On this basis, the distribution of urban grade scale and its first city in the Yangtze economic belt are explored. (3) the spatial characteristics of the urban system in the Yangtze economic belt are studied. The JAVA program developed by Baidu API interface and the distance (distance) function of Matlab software are used to calculate the Yangtze River Economic Belt. The straight distance between 110 cities in the economic zone; The driving distance and driving distance between 110 cities were measured according to Amap, and the data of straight line distance, traffic distance and time distance between cities were obtained by using fractal theory. The spatial distribution characteristics and traffic accessibility of the urban system in the study area are studied by two spatial scales in the three major zones of the east, west and west, and the gravity model is used. Based on the data of permanent resident population (GDP) and linear distance between cities in each city, the interaction between cities in the Yangtze River economic belt is analyzed. At the same time, the measurement of the spatial distribution of urban system in the study area is studied from two aspects: the quantitative measurement of the central position of the urban system and the quantitative measurement of the degree of dispersion. Based on the results of the study, some suggestions on the optimization of urban system structure are put forward from the whole, eastern, central and western regions of the study area.
