英文摘要	We developed a new tree-ring cellulose delta O-18 chronology for the southeastern Tibetan Plateau from Balfour spruce (Picea likiangensis var. balfouriana [Rehd. et Wils.]) that covered the period from 1600 to 2008, and compared the results with a previous study to explore climatic variations in the Nyingchi-Bomi area. Our tree-ring delta O-18 chronology correlated significantly with the previous study (Shi et al., 2012

Besides the significant positive correlations between tree-ring delta O-18 and the temperature and sunshine duration during the growing season, tree-ring delta O-18 was strongly negatively correlated with regional cloud cover, relative humidity, and precipitation in July and August. The correlations with cloud cover data were stronger than in previous research, but the correlations with precipitation and relative humidity in July and August were weaker. When Indian summer monsoon conditions prevail, regional hydroclimate variations (and especially cloud cover) have the dominant influence on tree-ring delta O-18 in the study area. Based on the regional data, delta O-18 in tree rings can be an effective proxy to infer the temporal variations in regional hydroclimatic conditions and the strength of the Indian Summer Monsoon. Our results reveal that the Indian Summer Monsoon weakened from 1600 to 1650, followed by continuous strengthening until 1740 and a slight weakening from 1740 to present. The temporal variations in the cellulose delta O-18 chronology generally corresponded well to the delta O-18 and glacier snow accumulation records found in ice cores from the middle Himalaya.
