1979—2019年的40年间,中国的城市化率由约20%增长到约60%,平均每年增长1%,中国也从一个8亿农村人口的国家,变成了一个8亿城市人口的国家。伴随着快速城市化进程,中国的城市面貌取得了翻天覆地的变化。在城市发展中,人工建造与自然之间一直存在着博弈。任何城市,在人口急剧增加、规模迅速扩张的时期,往往是城市内外的自然空间和公共空间被大量占用的时期,也是城市的生态问题和社会矛盾异常尖锐的时期。快速城市化进程使得中国在很短的时间内就从一个农业国走向了工业化和信息化国家,这是人类发展史中的一个奇迹。然而过去40年的快速城市化追求的更多是发展速度、规模、效率和经济利益,这种粗放的发展模式造成了建设用地大量侵蚀自然用地、城市及其区域的生态系统不断破碎、生态服务功能不断减弱的现实。

In the 40 years from 1979 to 2019,China's urbanization rate increased from about 20%to about 60%,with an average annual increase of 1%.China has also changed from a country with 800 million rural population to a country with 800 million urban population.Along with the rapid urbanization process,China's urban landscape has undergone earthshaking changes.In urban development,there has always been a game between artificial construction and nature.In any city,during the period of rapid expansion of population and scale,it is often a period in which natural and public spaces inside and outside the city are occupied in large quantities,and it is also an extremely acute period of urban ecological problems and social contradictions.The rapid urbanization process has made China move from an agricultural country to an industrialized and informatized country in a short period of time.This is a miracle in the history of human development.
