CLIMATIC TREND INDICATED BY VARIATIONS OF GLACIERS AND LAKES IN THE TIANSHAN MOUNTAINS

Under the control of geographical environment and the influence ofmodified west air mass, the mass balance of glaciers in the Tianshan Mountains hascontinously decreased since the 1970s. However, the lake level has increased gradually duo to the increase of precipitation. The interaction between temperature andprecipitation resulted in a normal and slightly more total amount of water resources inthe areas of the Tianshan Mountains. It is estimated that this climatic trend will lastto the early stage of the next century.
