Toumur - peak is one of the most developed modern Glacier areas in China. During past 40 years, glaciers in this area were in strong melting and retreating for climatic warming. Glacier meltwater plays an extremely important role both on water resource and stabilization of river runoff in the Tarim basin. Based on investigation on three different - sized glaciers in south slope of Toumur peak,this study has shown that glaciers in this area were in recession according to thickness thinning and area reducing. However,due to the influence of debris cover, the extent of area reduction and terminus recession varied widely for Toumur glacier and glacier No. 72,No. 74. Remote sensing technology was further used matching with field observation to determine the glacier change in quantity. Results shows that the three glaciers were lost 21. 4%, 15. 8% and 0. 3% of their areas in 1964,respectively. Meanwhile,the terminus retreats were at a rate of 41m·a~(-1),30m·a~(-1) and 1. 5m·a~(-1), respectively. The recession of larger glaciers have strong impace on water resource,thus those glaciers should attach important to its future variation. Topography and debris cover are main factors in differentiation ablation, and climatic warming may be the main factor forcing glacier in strong retreating.
