With the continuous improvement of the level of economic and social development and the continuous growth of the population, the degree of human exploitation and utilization of resources has deepened, resulting in a series of serious environmental pollution and destruction. It has threatened the normal life and production activities of local residents. In order to maintain the local ecological balance, we must take effective measures to ensure its healthy development, which is an urgent problem to be solved. In view of the special environment of Lhasa, this paper comprehensively analyzes different types of ecological retaining walls by using a variety of literature and field investigations, in order to find an effective way that not only meets the requirements of environmental protection, but also contributes to the sustainable economic development of Lhasa. Through the comparative analysis of several typical retaining wall structural forms common in Lhasa, the ecological stepped retaining wall structure forms suitable for Lhasa City are proposed, and the applicability of the stepped retaining wall is evaluated by qualitative analysis method, and it is concluded that the stepped ecological retaining wall has good adaptability and meets the construction requirements of Lhasa.
