Abstract： Glacial relics are crucial for reconstructing paleoclimate， recording the evolution of glacial climate and providing historical references for understanding modern climate change. Through an in-depth study of the geological characteristics of the Caolianling glacial relics， this article analyzes their typical landform types and glacial sediment features. By utilizing ESR dating data， the glacial genesis and evolution were reconstructed. The article explores Quaternary glacial climate factors， glacial development conditions， and evolutionary stages， offering a model for the protection of mid-latitude glacial relics in mid-latitudes worldwide.
