Review on the research progress in Zoigê grassland ecosystem;

Grassland degradation and desertification have become one of the prominent environmental problems in the Zoigê area.

The pollen record of 637cm in the upper part of 310m core RM from Zoige shows the occurrence of alpine meadow and desert-steppe in 22000-18 000aB.

The study involves the vegetational succession and climatic changes during the last 250000 years in the Zoige region, based on pollen analysis of 210 samples from upper 60m of Core RM.
