根据乌兰布和沙漠和沙漠北部出露的剖面记录，初步确认了全新统风成砂沉积层的划分，并据此作14C测年分析，认为全新世风成砂至少形成于2个时期：早全新世，14C年龄为距今7255a之前;晚全新世，14C年龄为距今2255或2630a以近，两期风成砂之间则是一个湖沼广泛发育的时期，乌兰布和沙漠形成时代的初步判定，至少可以认为在人类大规模开垦的汉代之前沙漠就已形成，且已经历了风成砂一湖沼的变化过程，说明沙漠的形成仍是以自然因素为主的过程，人类活动影响只是一个叠加于其上的因素．
Based on the profile records of the Ulanbuh desert and the northern deserts, the division of the Pleistocene aeolian sand sediment was preliminarily confirmed and the 14C dating analysis was conducted. It is concluded that the Holocene aeolian sand formed at least two periods: early Holocene, 14C dating back to 7255 a ago; late Holocene, 14C dating back to 2255 or 2630 a years ago, between two stages of aeolian sand is a lake development period, the era of the formation of Ulan Buh Desert Judging, at least, that the desert was formed before the man-made land reclamation in the Han Dynasty and has undergone a process of changing from a lagoon to a sandstorm, indicating that the formation of the desert is still dominated by natural factors. The impact of human activities is only one The factors superimposed on it.
