英文摘要	A 70-year history of precipitation 618 0 record has been retrieved using an ice core drilled from a plat portion of the firn area in the Guoqu Glacier (33 degrees 34 '37.8 '' N, 91 degrees 10'35.3 '' E, 5720 m a.s.l.) on Mt. Gelaclainclong (the source region of Yangtze River) during October and November, 2005. Based on the seasonality of delta O-18 records and the significant positive relationships between monsoon/non-monsoon delta O-18 values and summer/spring air temperature from the nearby meteorological stations, the history of summer and spring air temperature have been reconstructed for the last 70 years. The results show that both summer and spring air temperature variations present similar trends during the last 70 years. Regression analysis indicates that the slope of the temperature-delta O-18 relationship is 1.3 degrees C/parts per thousand. for non-monsoon delta O-18 values and spring air temperature, and 0.4 degrees C/parts per thousand. for monsoon delta O-18 values and summer air temperature. Variation of air temperature recorded in the ice core is consistent with that in the Northern Hemisphere (NH), however, the warming trend in the Gelaclainclong region is more intense than that in the NH, reflecting a higher sensitivity to global warming in the high elevation regions. In addition, warming trend is greater in spring than in summer.
