【英文摘要】Studies on aerosol and ice core from accumulation zone of East Rongbuk glacier, Mt. Qomolangma region indicate NH4+ and SO42- are the dominant ions in the aerosol here, Excess Cl- and Cl-/Na+ here are both much higher than those of the southern slope of Mt. Qomolangma. The sources of major inorganic ions in the collected samples are discussed. The reconstructed net accumulation from the East Rongbuk ice core has good correlation with the summer monsoon rainfall of North central India and East Peninsula India. So long-term series of Indian Summer Monsoon Rainfall of the two regions could be reflected by net accumulation of East Rongbuk glacier. The net-accumulation records of ice cores in Mt. Qomolangma region show clearly a sharp decline from the middle 1950s to the late 1960s, which might reflect the sudden climate change in the Asian monsoon region during that period. The negative relationship between δ18O record and net accumulation amount of the ice core recovered from East Rongbuk Glacier represent the "amount effect" of summer precipitation in this region. The variation of δ18O in the East Rongbuk ice core may be regard as a proxy of Indian Summer Monsoon activity which show low values in strong phases and higher values in weaken phases.
