英文摘要	This work quantifies glacier variations in the Naimona'nyi area of the western Himalaya by integrating glacier spatial data from ASTER and the Landsat series of satellite imagery at four different times: 1976, 1990, 1999 and 2003. Comparison of the results from individual images with those from the integrated method indicates that the integrated approach provides a better result. Glacier variations were mapped and analyzed; discrepancies between images could be detected and removed from the integrated data using remap tables in Arc/Info grid both graphically and numerically. Our results show that glaciers in the region both retreated and advanced during the last 28 years; however, retreat dominates. The variation of glaciers in the western Himalayan region is dramatic compared with other regions in high Asia. From 1976 to 2003, glacier area decreased from 84.41 km(2) to 77.29 km(2). Sequential images show that glacier areas shrank by 0.17, 0.19 and 0.77 km(2) a(-1), on average, during the periods 1976-90, 1990-99 and 1999-2003, respectively, suggesting that glacier retreat has accelerated.
