Landscape was considered as an image in the eye of human beings,and also an object for people experiencing physically and aesthetically on the basis of which landscape perception was regarded as a compound content,and focus of studies on this aspect has transferred from biology-based to social culture-based.It was proposed that landscape was not only a kind of space,but also a demonstration of human ideology,and for all viewers,landscape meant a kind of significance experience.According to Ferdiand de Sausure’s "signifier" and "signified",and Charles Sanders Peirce’s theory of categories,connotations of landscape symbols were discussed,landscape considered as a symbol text,and the relationship between "signifier" and "signified" borrowed to stress that landscape symbols expressed the significance accepted by audience via certain forms.On this basis,significance characterization of landscape symbols was classified into graphic symbols,indicative symbols and symbolic symbols.Symbolic symbols were believed as the most complicated ones because corresponding cultural backgrounds of viewers were required.Ambiguity and openness of landscape significance was elaborated,as well as its relationship with cultural context design,to provide reference for future designs.
