Alpine wetlands are located in cold regions at high latitudes and elevations,with unique climatic and ecological environment characteristics,providing important ecosystem services for human society,and maintaining regional and global ecological balance.Remote sensing information extraction from alpine wetlands can clarify the boundaries and spatial distribution of alpine wetlands,which is of great significance for exploring the spatiotemporal evolution law and driving force analysis of alpine wetlands.On the basis of combing the relevant literature,the study focuses on the identification of alpine wetland types and wetland ecosystem parameter inversion methods based on remote sensing;summarizes the technical means,advantages and disadvantages of each method and its applicability;and then puts forward the research prospect of remote sensing information extraction methods for alpine wetlands from the perspectives of multi-source data fusion,algorithm fusion and practical needs.
