| Abstract | Twenty surface pollen samples were collected along two regional transects: 1) from the mountains in the north, across the wetlands, to Sugan Lake; 2) from the lake, across the wetlands, to the desert (Fig. 1B). The NE Tibetan Plateau, located at a triple junction of influences of the Asian summer monsoon, westerly jet stream and Siberian high, is of considerable significance with regard to regional responses to global climate change. A number of fine-resolution paleoclimate studies on the NE Tibetan Pl t i t i (Zh t l 2003 Sh d t l The pollen assemblages from core SG03I at Sugan Lake were dominated by Artemisia and Chenopodiaceae together with some Poaceae Ephedra, Cyperaceae, Fabaceae and Nitraria. The percentage pollen diagram is divided into three zones based upon constrained cluster analysis (CONISS). Zone SG-1 (700 BC-340 AD; 558-372 cm): A/C ratios were constant and mostly around 1; Zone SG-2 (340-1530 AD; 372-137 cm: A/C ratios show bigger variations from 0.9 to 3.9; Zone SG-3 (1530-2003 AD; 137-0 cm): A/C ratios show higher frequency fluctuations and at 125 |
