摘要
In this paper, the glacier boundaries in the Luozha region of eastern Himalayas in the four periods were manually mapped. The results showed that: 1) from 1980 to 2007, the total glacier area decreased from 491.64 km2 to 410.87 km2; 2) the inverse relationship between initial area and change rate indicated that small glaciers receded faster than big ones; 3) glacier melt mainly occurred at area below 6 500 m; 4) during 1980～2007, the glacier areas reduced on all slopes; 6) the retreat rate of eastern Himalayan glaciers was faster than that of central and western Himalayas; and 7) finally, rising temperature along with little change in the precipitation in the Luozha region was the main factors that caused glacier retreat.
