“虚”空间作为空间类型中必不可少的一部分,并不是孤立存在于整体空间中,而是与其它空间相互融合的,其营造的效果往往出人意料。本文主要分析了“虚”空间的产生的原因,从人们对于生存空间在功能、心理、哲理、美学这四个方面上存在的模糊性进行分析。将这些模糊性与“虚”空间的本质结合,探讨其存在的意义,为目前室内设计发展的理论性研究做一些扩充。 As an indispensable part of the space type, “empty” space is not isolated in the whole space but integrated with other space, and the effect it creates is often unexpected. This paper mainly analyzes the reasons for the emergence of “virtual ” space and analyzes the fuzziness of people ’s existence in the four aspects of function, psychology, philosophy and aesthetics. Combining these fuzziness with the essence of the space of “virtual ”, this paper discusses the significance of its existence and makes some expansion for the theoretical research on the development of interior design.
