英文摘要	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 mapping projects include spatial continuity (areal extent) and thickness of the permafrost, air and ground temperatures and ground -ice content. All of those data have been retrieved, digitised and published in the Environmental and Ecological Science Data Center for West China. These maps represent the best understanding at the time regarding the distribution of permafrost in China and its changes over the past century. An updated map of permafrost in China, including frozen ground area, is also provided. The total area of permafrost in China is estimated at similar to 1.59 x 10(6) km(2) (glaciers and lakes excluded), and the area of seasonally frozen ground (excluding instantaneous frozen ground) is similar to 5.36 x 10(6) km(2). The total area of high-altitude (plateau and mountain) permafrost in China is similar to 1.35 x 10(6) km(2), the area of mountain permafrost is similar to 0.30 x 10(6) km(2) and the area of plateau permafrost is similar to 1.05 x 10(6)km(2). The latitudinal permafrost is located in the northern part of northeastern China, and its area is similar to 0.24 x 10(6)km(2). Additionally, some suggestions are proposed for future mapping of permafrost in China. Copyright (c) 2012 John Wiley & Sons, Ltd.
