This study aims to explore the characteristics of change and the rules of response of the soil bacterial community structure and diversity during the evolution of alpine wetlands. It also seeks to identify the leading factors affecting changes in the soil bacterial community, with the goal of providing a scientific basis for the restoration and management of alpine wetland ecosystems. Three different types of wetlands （original alpine wetland, alpine wet meadow, and alpine meadow） were selected to represent the succession process of alpine wetlands. The composition and diversity of the soil bacterial communities were analyzed using high-throughput sequencing technology. The findings revealed the following： ① Proteobacteria and Acidobacteria were the predominant bacteria, with their relative abundance exceeding 20.08%. In the alpine wetland, Nitrosomonadaceae and
