Abstract: Before the design is finally completed, the existence of design information is relied on the existence of design media, and there is an intimate relationship among design media, design capability and design activity. Even though the students have came into contact with emerging design methods and expression of various kinds of design media through various information dissemination channel, there are still a lot of teachers who do not have enough comprehension of the types and effect of design media, so the design media cannot feed back to the professional teaching efficaciously. This article sorts out the available design media in landscape design teaching first, including photograph, montage & photomontage, sketch & analytical diagram, descriptive drawing, perspective, model, video & animation & time-lapse photography, virtual reality & augmented reality & mixed reality & cinematic reality, graphic design, writing, speech and so on, then introduce their key point of use. The author maintains that, in each part of landscape design, teachers can choose appropriate design media for key training and design expression to cultivate students' basic design quality and basic capability to engage in other professional and working area.
