Bistatic　SAR　interferometry　is　an　essential　technique　of　observing　glacier　height　changes　and　geodetic　mass　balance.　Eastern　Nyainqentanglha　distributes　the　majority　parts　of　monsoonal　temperate　glaciers　and　presented　the　quickest　glacier　mass　loss　rate　at　High-mountains　Asia.　Most　recent　studies　on　glacier　mass　balance　at　Highmountains　Asia　focus　on　the　decadal-scale.　Here　we　obtained　TerraSAR-X/TanDEM-X　SAR　images　observed　in　-2012　and　-2017,　together　with　the　SRTM　DEM　that　observed　in　2000　we　derived　geodetic　glacier　mass　balances　in　two　periods　(2000　-　-2012/-2012　-　-2017).　We　proposed　three　InSAR　processing　procedures　for　deriving　geodetic　glacier　mass　balance　of　the　second　period,　which　yielded　basically　identical　results.　Topography　differencing　between　two　DEMs　derived　both　by　TerraSAR-X/TanDEM-X　can　provide　geodetic　glacier　mass　balance　information　at　a　sub-decadal　scale.　The　patterns　of　glacier　mass　balance　were　almost　identical　before　and　after　-2012　and　showed　with　slightly　increasing　rates　of　mass　loss.　Glaciers　distributed　at　the　southeastern,　which　were　most　clean-ice　type,　presented　with　quicker　loss　rates　than　the　glaciers　at　the　northwestern　part,　which　were　most　debris-covered　type.　Yanong　glacier,　which　was　the　largest　glacier　and　belong　to　laketerminating　type　showed　the　quickest　mass　loss　rate.　Decreasing　precipitation,　increasing　temperature　and　downward　shortwave　radiation　could　be　responsible　for　the　quick　glacier　mass　loss.
