Abstract: Study on high-density city is meaningful for practical issues since cities in the world were growing more and more high-density. Based on statistical data of 1513 cities with more than 500,000 population in year 2012 by Demographia, standard and global distribution of high-density cities were studied, the results indicate: Firstly, the standard of high-density city should be about 15,000 person per square kilometer, higher than this level city show “high-density” features which include land use, street and building, and transportation. Secondly, high-density cities are mainly distributed in developing countries which charaterized with lower industrialization, lower urbanization and larger population. Thirdly, high-density causes of developed country and developing country are different, as developed country is mainly caused by re-urbanization and developing country mainly by urbanization. Finally, several suggestions for further studies were given which include residential model, traffic management, resource distribution, public health, green space and so on.

摘要： 当今世界，高密度城市已在全球范围内大量出现。本文采用2012年Demographia公司发布的世界50万人以上城市人口密度数据，研究了高密度城市的门槛标准与全球分布特征。研究表明：高密度城市的门槛标准为15000人/km2，它在土地利用、街区建筑、交通方式等方面的表现出明显的空间环境特点。世界高密度城市主要集中分布在发展中国家，这些国家普遍具有工业化程度低、城市化水平低和人口规模大的特点。发达国家和发展中国家的高密度城市发展路径有较大差异，前者是由“再城市化”引起，后者则由“城市化”过程带来。有关高密度城市的深入研究意义重大，应着重关注其在居住形态、交通组织、资源配置、公共卫生、绿化环境等方面产生的问题。
