本文的目的是对发展中国家最近城市增长的模式和趋势提供一个广泛的概述。在过去的20年里，由于人口的迅速增长和世界经济在迅速的技术和政治变革的共同作用下发生了变化，许多城市地区经历了急剧的增长。现在大约有30亿人——几乎占世界总人口的一半——居住在城市定居点。虽然城市作为生产和消费中心在全球经济中发挥着日益重要的主导作用，但整个发展中世界城市的快速增长严重超出了大多数城市为其公民提供充分服务的能力。在今后30年里，预计世界上几乎所有的人口增长都将集中在发展中世界的城市地区。虽然目前关于可持续城市的大部分辩论都集中在世界上最大的城市群面临的棘手问题上，但大多数城市居民仍然居住在小得多的城市定居点。许多国际机构尚未充分认识到中小城市预期的迅速增长或城市穷人日益恶化的生活条件。实现可持续城市发展的挑战在非洲将特别艰巨。(C) 2005 Elsevier Ltd版权所有。
The purpose of this paper is to provide a broad overview of the recent patterns and trends of urban growth in developing countries. Over the last 20 years many urban areas have experienced dramatic growth, as a result of rapid population growth and as the world's economy has been transformed by a combination of rapid technological and political change. Around 3 billion people-virtually half of the world's total population-now live in urban settlements. And while cities command an increasingly dominant role in the global economy as centers of both production and consumption, rapid urban growth throughout the developing world is seriously outstripping the capacity of most cities to provide adequate services for their citizens. Over the next 30 years, virtually all of the world's population growth is expected to be concentrated in urban areas in the developing world. While much of the current sustainable cities debate focuses on the formidable problems for the world's largest urban agglomerations, the majority of all urban dwellers continue to reside in far smaller urban settlements. Many international agencies have yet to adequately recognize either the anticipated rapid growth of small and medium cities or the deteriorating living conditions of the urban poor. The challenges of achieving sustainable urban development will be particularly formidable in Africa. (C) 2005 Elsevier Ltd. All rights reserved.
