Changes in snowpack of the Changbai Mountain region over the last decade in reaction to global warming

As greenhouse gas emissions have been mounting in recent years, the issue of global warming has become more and serious, sparking a great deal concern. Among effects warming, melting snowpack is particularly pronounced. However, most current researches focus on vegetation biodiversity, there are some gaps studies snow mountainous regions China. This paper analyzes Landsat8 satellite images Changbai Mountain area past 10 years through QGIS programming algorithms to study trend change, correlation between change causes melting. The analytical methods used this include NDSI, NDVI, supervised classification image binarization. From 2014 2023, snow-covered areas Nature Reserve decreased dramatically, especially northwestern part, middle part edges Mountain. rate reached significant 13.979%. shows an increasing negatively correlated with change. In order alleviate challenge melting, ecological engineering, new energy sources rigorous regulation human activities all essentially necessary. future, it expected that research will profound positive impact management region, conservation resources mitigation warming.
