在内蒙古浑善达克沙地中发现了(10040±100)aBP的古鱼鳞云杉(Piceajezoensis)木材,这是我国北方迄今为止发现的较古老的木材标本之一.孢粉和哺乳动物化石资料进一步证明,此地区在全新世早期存在以云杉和桦为主的针阔混交林.这一发现对于分析当地的古气候、古植被以及景观演化有着重要的意义.

The sporopollen and mammalian fossil It is further proved that there are coniferous and birch-dominated mixed coniferous forests in the early Holocene, which is of great significance to the analysis of the paleoclimate, palaeo-vegetation and landscape evolution in this area.
