[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.
