中国沿海省份大城市紧凑程度测算方法与分析

Measurement and Analysis of Degree of Compactness of Large Cities in Coastal Provinces in China

近年来,随着城市化的快速发展,中国城市建成区快速向外扩张,农用地大量减少。为控制这一现象,中国政府颁布了相关政策,倡导紧凑城市的发展模式,为保证政策的顺利实施,弄清中国城市紧凑程度的现状是非常重要的。中国沿海省份的大城市拥有较高的人口密度、建设密度以及资本密度,城市快速扩张、农用地大量流失等问题尤为突出。因而本文选取东部沿海省份中大城市作为研究对象,从紧凑城市、土地集约利用等相关概念着手,提出适用于评估中国沿海大城市紧凑程度的指标体系,并采用主成分分析的定量方法,计算其紧凑程度的基本情况,并着重分析和总结沿海省份紧凑城市发展状况以及发展特点。

China is one of the developing countries with fast urban growth rate, and correspondingly the area of arable land of China is decreasing rapidly. To control expansion of large cities and to protect the arable land, the Chinese gov- ernment has published a series of poli- cies, and considered that cities should de- velop towards the compact cities para- digrm To put the compact city paradigm into practice, it is important to explore the status quo of the compact degree of these cities. The large cities in coastal provinces are the most developed region experiencing rapid urban expansion, with the high population density, high gross national product and high built-up area density in China. This paper will select the large municipalities in coastal prov- inces as case studies to reveal the degree of compactness and to summarize the fea- tures of the development of compact cities.
