Diatom-based reconstruction of Holocene environmental changes in Angren Lake, Southern Tibert

摘要

Based on the diatom analysis the climatic sequence between 11 000 and 6 00 aBP in Angren, southern Tibert is established, i.e. cold peirod(11 095-9 970 aBP)→tempeature peri- Od(9 970-9 870 aBP)→Anathermal(9 870-9 770 aBP)→cool-dry period(9 770-8 740 aBP) →super-megathermal(8 740-8 590 aBP)→Megathermal(8 590-5 970 aBP). And the opinon that the reaction of diatom to temperature change is more sensitive than to other ecological fac- tors has been pointed out and certified.
