Based on remote sensing monitoring of land cover in typical experimental plots with complex ecological backgrounds in the Lancang River Basin, this paper discusses the technical methods for establishing land cover monitoring in the mountainous areas based on the application of remote sensing technology, and provides a basic research for the overall monitoring system of integrated development in the basin. The results show that based on the special remote sensing image processing software, the spectral response curves of typical sample plots in the study area are designed to extract the obvious separability of the land cover classes in the study area, and the main types of land cover are extracted and combined The application of multi-level remote sensing classification method can obtain many advantages and more practical classification results than single method of automatic pattern recognition or single visual interpretation method, which is an effective and effective method for land cover monitoring in mountainous areas. Feasible and relatively easy to operate method.
