Terrain:

The main landform type is low mountains and hills, which are distributed in the southeast of the urban area and belong to a part of the Daheishan Mountains, with a slight northeast-southwest trend. Most of them are between 250 meters and 350 meters above sea level, and the relative height is between 50 meters and 100 meters. Dadingzi Mountain in the east is 407 meters above sea level and consists of metamorphic rock series such as granite and andesite.

Mountainous areas and hilly areas account for a small part of the urban area. There are forests in mountainous and hilly areas, and some alluvial plains and basins between low mountains are agricultural areas. Yitong River flows from the northern foot of Daheishan and passes through the eastern part of the city from south to north. Narrow estuaries have good conditions for building reservoirs.

Climate:

The climate of Changchun City is in the transitional zone between the humid eastern mountainous area and the semi-arid western plain, belonging to the temperate continental semi-humid monsoon climate type. Although the east and south are not far from the ocean, the role of summer monsoon is weakened due to the blocking of Changbai Mountain. The west and north are flat Songliao Plain, and the Siberian polar continental air mass is unobstructed, so the climate is generally characterized by drought and windy in spring, short and warm in summer, obvious temperature difference in autumn and long and cold in winter.
