英文摘要Annually laminated sediments in Lake Xiaolongwan, northeast China, contain a suite of n-alkanes (C-17-C-33) with a strong odd over even carbon number predominance. Biomarker n-alkane proxies (average chain length, Paq ratio, grass/tree ratio, carbon preference index and compound-specific delta C-13 values) were used to reconstruct climate changes that occurred over the last millennium. Compound-specific delta C-13 values show large differences between the distinctive chain length groups of n-alkanes that originate from algae, aquatic macrophytes and terrestrial plants. Long-chain n-alkanes (C-27-C-33) are predominantly derived from leaf wax lipids in the forest. Variations in long-chain n-alkane delta C-13 values may mainly record water-use efficiency, inasmuch as the contribution from C4 plants is negligible in the Lake Xiaolongwan catchment. Short- and middle-chain n-alkanes are mainly from algae and aquatic plants. They are strongly depleted in C-13. This feature may be linked to a methane-derived, negative delta C-13 pool and lake overturn, which regulates dinoflagellate blooms. Parallel fluctuations are observed in delta C-13(27-31) values, Paq, and the grass/tree ratio throughout the record. Variations in delta C-13(27-31) values and Paq are in agreement with historical documents on summer and winter climate conditions. They support earlier suggestions that delta C-13 values in the long-chain n-alkanes and Paq may be useful indicators of effective precipitation or drought stress in this forested area. The delta C-13(27-31) index and Paq show distinct decadal variations. Periods with high delta C-13(27-31) values and a low Paq index correspond with the warm phases of the Pacific Decadal Oscillation (PDO). Values are reversed during PDO cool phases. At the decadal timescale, summer monsoon rainfall in northeast China over the last millennium may have been regulated mainly by the PDO.
