Remote sensing technology reveals significant glacier retreat in the Qilian Mountains, indicating climate change impacts on water resources and ecology.
This research uses remote sensing technology and GIS methods to conduct a detailed analysis of the glacier area changes in the middle section of the Qilian Mountains from 2014 to 2024. The study area, located in the middle section of the Qilian Mountains, is a crucial water conservation area and ecological security barrier in the northwest region. By preprocessing multiple remote sensing images, extracting glacier boundaries, and calculating the area, the study reveals the dynamic changes in the glacier area during this period. The results show that the glacier area in the middle section of the Qilian Mountains has shown a significant retreat trend during this period. Although the speed and extent of the glacier retreat vary across different years and regions, the overall trend is clear. This change not only affects the regional water resource balance but may also have profound impacts on the local ecological environment and climate system. Combining observational data, this study not only provides a scientific basis for the protection and rational use of glacier resources in the middle section of the Qilian Mountains but also offers valuable insights into glacier research under the backdrop of global climate change.
