Based on the diatom analysis the climatic sequence between 11 000 and 6 000 aBP in Angren, southern Tibet is established, i.e. cold period (11 095-9 970 aBP)→temperate period (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 opinion that the reaction of diatom to temperature change is more sensitive than to other ecological factors has been pointed out and certified.
