This paper expounds Lewis Munford's urban theory and academic thought

significant for reference in our urban science research and urban planning and construction

with seven aspects: the cultural function of a city

the citizens' dominating role

the construction of city's cultural facilities

the urban renewal without demolishing all old buildings and the meaning of historical-cultural buildings

that it is not the larger the better for a city

the combination and intergration of city and countryside and the advocacy of going toward an ecological civilization.
