拼装车也是借用沙地车的一个变种，就像做沙地车一样，拼装车也是把车子上原装的部件换成自己订制的，外观则仿制现有的量产车，改装车或者是概念车。

The paleochannel-Ⅱ might form during the Holocene Optimal period.

古河道-Ⅴ形成于风沙-Ⅱ和Ⅲ期形成之前，可能是末次冰期之前，即中更新世或更早，这时河流能够进入古松辽大湖；古河道-Ⅳ形成于风沙-Ⅱ和Ⅲ期形成之时，可能是末次冰期时期，这时河流与松辽大湖萎缩，规模减小，河流已不能进入松辽大湖，而是消失在沙地之中；古河道-Ⅲ形成于风沙-Ⅱ和Ⅲ期形成之后，可能是末次冰期末期的冰消期，这时气温升高，大量的冰雪融水进入河流，促使河水漫流，流入沙垅垅间洼地，开始造成古西拉木伦河、古老哈河与教来河水文网之间的相互联系；古河道-Ⅱ形成于全新世适宜期时期，统一的西辽河形成，伴随气候变化，出现多次风沙进退，对应于风沙-Ⅰ期；河道-Ⅰ是现在，同属于风沙-Ⅰ期，活动沙地集中在翁牛特等地。
