英文摘要

A review of the published records of Late Pleistocene-Holocene climate of the western Himalaya reveals that though the Ladakh area in the Trans-Himalayan region has been experiencing an and climate for more than 40 ka B.P., it was relatively less arid during the last glacial period when compared to the Holocene conditions. Within the last glacial and phase there were several short, warm and moist events (interstadials) around 30, 21, 18.375, 16 and 10 ka B.P. Many of them have been recognized from the Greater and outer Himalaya also. Data for the Holocene from the Ladakh and other Trans-Himalayan sites are almost lacking. The climate of the Greater and outer Himalaya was warm-moist during most of the Holocene, which was interrupted by short phases of colder and drier climate around 8.3-7.3 ka B.P., 6- similar to 3 ka B.P. and 850 years B.P. Contemporaneous paleoclimate records from Peninsular India also indicate relatively dry conditions for the last glacial period and comparatively warm-moist conditions for a major part of the Holocene. The interstadial phases within the last glacial period in the Trans-Himalayan region might have coincided with the enhanced Western disturbance/northeast monsoon in the Indian subcontinent.
