英文摘要Surface snow samples were collected during the 14th (1997/1998) and 24th (2007/2008) Chinese National Antarctica Research Expeditions along a transect from Zhongshan Station to Dome A. The stable oxygen isotope ratios of these samples were measured to investigate their relationships with temperature and geographical parameters (latitude, longitude, altitude and distance to the coast). The results reveal a strong positive correlation (R=0.945) between delta O-18 and mean annual temperature, with a gradient of 0.84aEuro degrees A degrees C-1, which is a little higher than that in Terre Adelie Land. Regression analyses also show that the delta O-18 of surface snow is strongly correlated with distance to the coast (R=0.942), latitude (R=0.942), and altitude (R=0.941). But no significant correlation was found between delta O-18 and longitude in study area. Altitude should be the most important factor influencing the delta O-18 distribution because of distinctive topography. The delta O-18-altitude and T-altitude gradients along this transect are determined to be -1.1aEuro degrees/100 m and 1.31A degrees C/100 m, respectively.
