The planning and design of urban space of mountain terrain should be based on rational analysis, combining imagery thinking including landforms, integrating life experience and perceptual knowledge to effectively coordinate and utilize various existing and future natural and human landscape elements, and arrange new design elements to support, balance and perfect the series of shapes in mind which need to be reorganized, and thus develop a new space art image full of artistic conception. For the design of urban sculptures, normally the design and creation generally follow the process of conceptionvisualization- composition. However, urban sculptures in mountain terrain are constructed according to special mountain terrains on the basis of general process. This paper adopts the method of case study of typical mountain sculptures to conduct studies on the construction of urban sculptures in mountain terrain, and summarizes the methods of construction of urban sculpture in mountain terrain in view to adding mountain elements and design method for the teaching of urban sculptures design.
