在我们涉及公共艺术本身之前,试先就它栖身其间的城市及城市化方面的一般性概念等问题作一简要的论述。 “一切伟大的文化都是市镇文化,这是一件结论性的事实……世界历史是市民的历史,这就是‘世界历史’的真正标准,这种标准把它非常鲜明地同人类史区分开来了。民族、国家、政治、宗教,各种艺术以及各种科学都以人类的一种重要现象,市镇,为基础”德国历史哲学家斯宾格勒如是说。尤其是,约从18世纪末詹姆士·瓦特发明蒸汽机前后至20世纪第二次世界大战之后,以城市为基础的经济、科技和文化艺术空前发展的社会历史经验,使国际学术界在普遍意义上对人类社会的“现代化”标准的探讨中,得出了若干方面的共识。在人的社会生活形态的现代化方面明确指出其标准即是城市化,即相对于乡村、居民以非农业活动为主的社会形态。在中国,据国家统计局1997年公布的数字,1996年全国总人口已超过12亿,其中城镇人口为35950万人,仅占全国总人口的29.4％,若以美、日、英、法、加拿大等城市化程 Before we talk about the public art itself, try briefly a brief discussion of the general concepts of urban and urbanization where it resides. “It is a conclusive fact that all great cultures are urban cultures ...

In particular, from the time when James W. Watt invented the steam engine to the 20th century after the Second World War in the late 18th century, the social and historical experience of urban-based unprecedented development in economy, technology and culture and arts made the international academic community universal On the “modern” human society to explore the standard, reached a number of consensus. In terms of the modernization of human social life form, it clearly states that its standard is urbanization, that is, the social form in which the residents mainly regard non-agricultural activities as opposed to the rural areas. In China, according to figures released by the National Bureau of Statistics in 1997, the total population of the country in 1996 exceeded 1.2 billion, of which 359,500,000 were urban residents, accounting for only 29.4% of the total population of the country.
