Abstract. Urban architectural heritage as a part of cultural heritage, its surrounding buildings will have a certain visual impact on the cultural heritage itself. This paper presents a method for calculating visual impact and applies it to the field of urban architectural heritage. In this method, the visual radius and visual range are calculated based on the theoretical knowledge related to the range of human eye line of sight and the curvature of the earth, and then the visual projection plane is established. Then, through skyline analysis and spatial relationship calculation, the urban architectural heritage and its surrounding buildings are projected. Calculate the visual impairment index through the projection area and the projection surface area to quantify the visual impact. By calculating the visual impact in The Lama Temple area, it is proved that the method presented in this paper is effective and advanced in practical application.
