Abstract: In order to study the influence of freeze-thaw process on the formation and evolution of oitering river, natural model test was used to simulate the freezing process and melting process of wandering channel. The study showed that, in the process of the melting of the frozen river border with bank and riverbed gradually melts, at the bottom of the river will gradually appear again wandering type characteristics and wandering river type strength determined by the degree of riverbed melting, and river melt degree on the water with the test of time analyzing and the rise of temperature. And freezing process type wandering channel characteristic gradually disappear, the frozen river and riparian conditions gradually in the process of hardening, limits the incised and to expand on both sides of the speed of river, upstream inflow decreases at the same time, makes the river evolution process gradually slow down, when central river water consolidation, river evolution near standstill.
