【摘要】To predict future spatio-temporal patterns of climate change,we should fully understand the spatio-temporal patterns of climate change during the past millennium.But,we are not yet able to delineate the patterns because the qualifies of the retrieved proxy records and the spatial coverage of those records are not adequate.Northern Xinjiang of China is one of such areas where the records are not adequate.Here,we present a 500-yr land-surface moisture sequence from Heiyangpo Peat (48.34°N,87.18°E,1353 m a.s.l) in the southern Altai Mountains within northern Xinjiang.Specifically,peat carbon isotope value of cellulose (δ13Cellulose) was used to estimate the warm-season moisture variations and the degree of humification was used to constrain the δ13Ccelluose-based hydrological interpretation.The climatic attributions of the interpreted hydrological variations were based on the warm-season temperature reconstrueted from Belukha ice core and the warm-season precipitation inferred from the reconstructed Atlantic
