摘要

Objective Betula microphylla Bunge,as a resource treasury of desert biodiversity,is a pioneer plant in saline-alkaline soil amelioration.According to previous research,Ebinur Lake,north Xinjiang,is a representative saltwater lake with 92-131 g/L salinity(Li et al.,2006).However,surprisingly,our research team found a scrap of freshwater wetland,meadow bog gleied soil,with many birch trees of Betula microphylla.Why does Betula microphylla grow in freshwater wetland?Was Betula microphylla growing there in ancient times?Therefore,it is necessary to strengthen research into the biodiversity evolution in the Ebinur Lake area.By using the data from palynology and 14C,we reveal the ecological evolution of the Ebinur Lake wetland area since 2580 cal.a B.P.,which could provide a reference frame for ecological civilization construction.
