ne-level: 2" class=MsoNormal>The Zigetang Lake is an enclosed lake, located in the hinterland of the North Tibetan Plateau and within the marginal region of southwest monsoon. There is no distribution of glacier in the catchment, and the precipitation controlled by the southwest monsoon is the main water supply for the Zigetang Lake. Therefore, the expansion and contraction of lake water area reflects the changes of southwest monsoon directly. The analysis results for a 740 cm-long core drilled in the central Zigetang Lake show that this core has completely covered the whole Holocene period and that the carbonate concentration decreased greatly during 9.3~8.9, 8.3~7.8, 5.0~4.7, 4.0~3.8, and 3.1~2.7 cal ka B.P., respectively, indicating the desalination of the lake and the rise of the lake level.
