Abstract:
Jiagedaqi District of Greater Khingan Range area in Heilongjiang Province, located in the northeastern part of China, belongs to the typical high altitude cold regions, and is one of the most serious groundwater overflow icing problem areas in China. Located in the east area of Jiagedaqi, East River is a representative area of the regional overflow icing phenomenon. With the methods of field reconnaissance survey and hydrogeological exploration, this article not only analyzed the three formation stages and characteristics of the overflow icing phenomenon in the region, especially the meteorology, watershed underlying surface and frozen layer on the influence of the phenomenon, but also pointed out that the shallow aquifer in the watershed underlying surface factor and frozen layer of Jiagedaqi District were key influencing factors to form the unique overflow icing phenomenon in the region.
