本文主要论述了壁画与外空间的关系。以空间形态为基础,通过对壁画内空间与外空间的区分与界定,来探讨壁画和外空间所构成的有机关联及其间的互动关系。提出壁画应该以三维空间作为构图、造型、设计的最基本参照,并和其周遭的自然空间形成对应转换关系,从而达到人造壁画空间与自然外空间之间的相互补充和融通。 This paper mainly discusses the relationship between murals and outer space. On the basis of the spatial form, this paper discusses the organic relationship and the interaction between the murals and the outer space by distinguishing and defining the inner and outer space of the murals. It is suggested that the mural painting should take the three-dimensional space as the most basic reference for composition, modeling and design, and form the corresponding conversion relation with the natural space around it so as to achieve the mutual complement and integration between the artificial mural painting space and the natural outer space.
