How to draw a more accurate distribution map of permafrost with climate warming and permafrost degradation to provide data support for cold region engineering? Professor Shan Wei's team from the Cold Region Science and Engineering Research Institute of Northeast Forestry University has completed a 30 meter resolution map of the distribution and spatiotemporal changes of permafrost in Northeast China. The relevant results have recently been published in international journals such as "Sustainable Development" and "Applied Science". This marks a new breakthrough in large-scale high-resolution mapping of permafrost in Northeast China.

Detailed and detailed spatial distribution and changes of permafrost are important foundations for research on regional landscape, ecosystem changes, and linear engineering stability, as well as data support for engineering planning, construction, and environmental change prediction in cold regions.

The 30 meter resolution mapping of the distribution and spatiotemporal changes of permafrost in Northeast China reveals the degradation laws of permafrost from multiple perspectives and scales, providing scientific data support for research on climate change, forest and environmental changes, carbon emissions and absorption, and cold region engineering in Northeast China.
