本文以四个广场案例来对比研究城市广场设计中广场与其周围建筑的关系,重点讨论广场空间的“围合感”与广场边界的“完整性”问题;进而以老子的“有之以为利,无之以为用”为理论依托,提出“建筑以为‘利’,广场以为‘用’”的设计概念,为当下中国城市广场设计提供一点启示。 In this paper, four square cases are used to compare the relationship between square and its surrounding buildings in the design of city square, with a focus on the issue of “perfection” of square space and “integrity” of square border; Some think it is advantageous, and do not think that it is based on the theory. It puts forward the design concept that "the building is thought as ’benefit’ and the square thinks it is ’use’, which provides a little enlightenment for the present design of China’s city square.
