Distribution of Permafrost in China: An Overview of Existing Permafrost Maps
ABSTRACT Many permafrost maps in China have been compiled since the early 1960s. The scales of these maps range from the local (1:600 000) to the regional scale (1:10 000 000). The permafrost classification systems differ among these maps. The indices for permafrost classification used in these mapp...
