中文摘要 | According to the glacial landforms and deposits with the optically stimulated lumi-nescence(OSL) dating results,two glacial stages of the last glacial cycle(LGC) and Late Glacial were identified.The Late Glacial stage(Meteorological Station glacier advance) took place about 11 ka(11.3±1.2 ka),and the last glacial maximum(LGM),named Black Wind Mouth glacier advance,occurred at 20 ka(20.0±2.1 ka).Based on the Ohmura's formula in which there is a relationship between summer(JJA) atmospheric temperature(T) and the annual precipitation(P) at ELA,the present theoretical equilibrium line altitude(ELAt) in Changbai Mountains was 3380±100 m.Six methods of accumulation-area ratio(AAR),maximum elevation of lateral moraines(MELM),toe-to headwall altitude ratios(THAR),the terminal to summit altitudinal(TSAM),the altitude of cirque floor(CF),and the terminal to average elevation of the catchment area(Hofer) were used for calculation of the former ELAs in different stages.These methods provided the ELA for a range of 2250-2... |
