南京商业中心演化与布局研究

Research on Commercial Center Evolution and Distribution in Nanjing

随着时代的发展,城市商业活动的频率和强度明显增多和增强,商业中心的作用越来越重要。商业中心的合理布局不仅可以满足消费需求、促进商业中心繁荣,而且会影响城市空间结构和居住区、商业区等的功能布局。为此,本文以南京为研究区域,总结商业发展的现状特征,研究城市商业中心体系的演变过程,分析影响商业中心形成与分布的因素。在此基础之上,通过圈层距离法和可达性方法,评价南京商业中心布局的合理性,并提出优化空间布局的方案。研究发现南京商业中心的分布具有时代特点,在20多年的发展过程中,其规模和等级结构均发生变化。其次,目前南京商业中心布局不合理,中心城区密度过大,郊区数量不足;要通过合理规划和增强交通可达性等方法加以解决。

City functioned as production, resident and administration and market based on commercial activities together form the modern city. With the development of time, the frequency and intensity of urban commercial activities increase and enhance significantly, and then the role of commercial center is more important increasingly. The reasonable layout of the business centre can not only satisfy the consumer demand and promote the business center prosperity, but also affect the city space structure and the function layout of residential and commercial districts. So the article sums up the current characteristics of the commercial development, studies the evolution process of urban commercial center system and analyses influencing factors of formation and distribution of commercial center based on minimum statistical unit for grid by the method of sphere distance and accessibility in Nanjing. Then on this basis by the methods of circle distance and accessibility, the paper evaluates the rationality of commercial center distribution in Nanjing and puts forward the program of optimizing spatial distribution. The basic conclusion is that first of all, it has time characteristic about Nanjing commercial center distribution, with the development of more than 20 years the scale and level structure being changing. Secondly, Nanjing commercial centre layout is unreasonable, namely the density of urban center area being too large and the quantity of suburban being too short. To solve the problem, we should take the method of reasonable planning and strengthen traffic accessibility.
