摘要
Pollen analysis of 1 m deep sediment core from Naychhudwari Bog, Himachal Pradesh has revealed that around 1300 to 750 yrs BP, the alpine belt of this region experienced warm and moist climate. The glaciers receded and the tree-line ascended to higher elevations. Around 750 to 450 yrs BP, intermittent deterioration and amelioration of climate have been witnessed. From 450 yrs BP onwards, the glaciers advanced and consequently the tree-line descended under the impact of cold and dry climate in the region.
