序言

Preface

城市一个世纪前,全世界仅有十分之一的人口居住在城市中。时至今日,这一比例已经超过了50%。城市是商业、文化与创新的源动力,也是背景互不相同的人们共同生活、工作与休闲的基本群落结构。在人口增长率较高的国家——例如在全球七十亿人口中占据五分之一的中国——城市化的速度令人惊叹。2011年,中国的城市总人口超过了农村总人口,大量涌入城市的农村人口给城市带来了极大的压力。这种从农村到城市的人口结构的根本性转变是戏剧化的,它使整个国家的城市规划与再规划都处于一种史无前例的尺度。中国城市的快速发展虽然处于这种史无前例的尺度,但也绝不是独一无二的。

THE CITY A century ago only a tenth of people lived in cities; today that are the drivers of commerce, culture and innovation - fundamenta to live, work and play. figure has risen to more than half of the total global population, Cities community structures where people from diverse backgrounds come In high growth countries such as China, which already makes up almost a fifth of the 7 billion-person global population, urbanisation is happening at an incredible speed. In 2011, the number of people living in China＇s cities surpassed those in rural areas, placing huge pressure on existing cities to absorb an ever increasing migrant population. This dramatic and fundamental shift in China＇s demographic landscape from rural to urban has prompted a nationwide city planning and re-planning scheme on an unprecedented scale.
