“人们为了生活而聚集到城市,为了生活得更美好而居留于城市。”当亚里士多德对城市意义作出如上判断之时,他肯定无法预料到,两千多年之后,以他这句名言为口号的城市已经成为人类发展的一大难题。刘易斯·芒福德在《城市发展史——起源、演变和前景》 “People gathered in cities to live and live in cities for a better life.” When Aristotle made the above judgment on the meaning of the city, he certainly could not predict that after two thousand years, His famous slogan, the city, has become a major challenge to human development. Lewis Mumford in “The History of Urban Development - Origin, Evolution and Prospects”
