Wetland ecosystems are essential to the preservation of biodiversity. Plateau wetland ecosystems are vital components of wetland ecosystems, characterized by diverse wetland types and fragmented land distribution. In the extraction of plateau wetlands, there are such issues as inaccuracy in classification, inadequately fine categories, and difficulty in extracting vegetated wetlands. The aim of this study was to establish a new classification framework for extracting detailed information about plateau wetlands, and the Dianchi Basin was used as the study area. Using Gaofen-2 (GF-2) imagery from 2019&#x2013;2021, land cover information was extracted by applying nearest neighbor classification and random forest classification. Wetlands were then extracted from the land cover data using ecological rule classification, and a detailed wetland map of the Dianchi Basin was obtained in 2020 with a 1 m resolution. Results showed that the production accuracies of forest wetlands, shrub wetlands, meadow wetlands, rivers, ponds, reservoirs, and lakes in the Dianchi Basin were 89.4&#x0025;, 87.9&#x0025;, 91.4&#x0025;, 90.7&#x0025;, 89.9&#x0025;, 92.9&#x0025;, and 95.9&#x0025;, respectively, and the user accuracies were 94.9&#x0025;, 92.4&#x0025;, 92.6&#x0025;, 95.4&#x0025;, 94.2&#x0025;, 91.0&#x0025;, and 99.4&#x0025;, respectively. Compared to the CAS_Wetlands, this study categorized the five categories of plateau wetlands into seven types with greater specificity and increased the spatial resolution of wetland mapping from 30 m to 1 m. This study can provide a new reference framework for wetland extraction and support the conservation of plateau wetland ecosystems.
