英文摘要This research quantifies lake level variations in the Siling Co, Co'e and Bangor Co salt lakes in Central Tibet from 1976 to 2010, and most notably for the 2000-2010 periods. In particular, the effects of different water replenishment modes on the lakes have been analyzed. Here we have provided new evidences for climate warming and accelerated glacial ablation on the Central Tibetan Plateau from 2000 to 2010. Based on fieldwork involving Differential Global Positioning System (DGPS) surveying and Remote Sensing (RS) interpretations of the lake area, we have drawn the following conclusions. (1) From 1976 to 2010, the process of lake level variation in Siling Co can be divided into two stages. From 1976 to 2000, the lake level rose 4.3 m in a steady fashion (from 4530 to 4534.3 m); the rise rate was 0.18 m/a. From 2000 to 2010, the lake level rapidly rose 8.2 m (from 4534.3 to 4542.5 m), with a dramatically higher rise rate of 0.82 m/a. Compared with the rapidly increasing lake level of Siling Co from 2000 to 2010, the fluctuations observed at Co'e and Bangor Co were smooth and inconspicuous. (2) From 1976 to 2009, the lake area of Siling Co experienced a steady-rapid-steady expansion pattern. The lake area of Siling Co increased 656.64 km(2) in the 34 years to 2010, a proportional growth of 39.4%. This was particularly significant in the 2000-2010 period, when the lake area of Siling Co increased by 549.77 km(2), a proportional growth of 30.6%. (3) According to correlation analysis, the rise in regional temperatures, which has led to the ablation of glaciers, is the main reason for the rapid rise in Siling Co lake levels in the 10 years to 2010. During this period, Siling Co rose approximately 8 m as the direct result of glacial melting. An increase in precipitation in the Siling Co catchment area is the secondary factor. This contrasts with Bangor Co, where the dominant factor in lake level change is the long-term increase in precipitation; here, the increasing temperature is the secondary factor.
