• The accumulation season is from May to September (Ye and others, 2006). Because of the remoteness and very high altitude of the Jianggudiru Glacier, there has been little fieldwork on monitoring its changes, and understanding of this glacier is limited. The down-glacier elevation change of the SJG hints that there may have been a surging event before 2000 that caused a big down-glacier elevation rise of the SJG and that the elevation then dropped after the surge. Because there have been no previous studies on the surging phenomena of the headwater glacier in this area, the results from the previous DEM differencing method were examined according to changes in the time-series Landsat TM images from 1988 to 2015 in order to realise a more comprehensive understanding of the glacier change behaviour. [...]the glacier surges were not synchronised with the meteorological change, and the SJG and NJG were not changing together even though they are very close to each other. [...]the internal surge mechanism in each glacier dominates its behaviour over this time period.
