根据对乌兰布和沙漠北部地区全新世风沙和湖泊沉积记录及其沉积时代进行分析,认为全新世以来,乌兰布和沙漠北部地区地貌演化经历了4个主要的发育时期:Q33~Q41湖泊地貌发育时期,Q41风沙地貌发育时期,Q42湖(河)(屠申泽)地貌发育时期和Q43风沙地貌发育时期。全新世中期屠申泽最为繁盛的时期,湖泊相互沟通,范围几乎占据了整个乌兰布和沙漠北部地区,之后经历了自南向北的萎缩、分化过程,而屠申泽的萎缩、分化过程正是乌兰布和沙漠晚全新世风沙地貌发育并不断扩张的过程,这是一个以自然环境变化为主因、以人为影响为辅因的变化过程。
According to the record of eolian & lake deposit and their chronology date in the northern Ulan Buh Desert in the Holocene, it is stated that Ulan Buh Desert's process of geomorphic evolution in the Holocene can be divided into 4 stages: (1) Lake Geomorphy stage in Q33-Q41. (2) Eolian Geomorphy stage in Q41. (3) Lake (Tushenze Lake) Geomorphy stage in the middle Holocene (Q42). (4) Eolian Geomorphy stage that the wind power was gradually stronger in the late Holocene (Q43). Tushenze Lake had been the united largest scale in the middle Holocene, when it had occupied the all most of the northern Ulan Buh Desert. Then Tushenze Lake had began to shrink and separate into a several little lakes. The process of the lake shrunk was none other than the one of the desert expanded, which resulted from natural environmental evolution mainly.
