Geographical characteristics of Jinan
The topography of Jinan can be divided into three zones: the Yellow River in the north, the piedmont plain in the middle and the hilly and mountainous areas in the south. The main peaks in the territory are Changchengling, Paomaling, Ladder Mountain and Heiniuzhai. There are more than 3,000 square kilometers of mountains and hills and 5,000 square kilometers of plains. The highest altitude is 1 108.4m, the lowest altitude is 5m, and the height difference between north and south is 1 100m.

Jinan has many springs because of its unique topographical and geological structure. Jinan is located in the heart of Shandong Province, with low mountains and hills in central and southern Shandong and alluvial plains in northwest Shandong, just sandwiched in the middle. It is a gentle monoclinic structure with a height difference of more than 500 meters. The urban terrain is naturally high in the south and low in the north, which is conducive to the collection of surface water and groundwater into the urban area.

Jinan underground is soluble limestone. After many tectonic movements and long-term dissolution, a large number of karst ditches, caves and underground rivers have been formed, which has become an underground pipe network capable of storing and transporting groundwater. A large amount of groundwater in the southern mountains of Jinan, criss-crossing limestone strata, travels southward, and meets closely organized magmatic rocks in the northern suburbs, like a natural stone wall, blocking the water veins.

Eventually, a large amount of groundwater trapped here, with strong pressure, gushed out of the ground along many cracks and passages connecting the ground, so natural springs appeared. It is precisely because of this geological structure that although Jinan is located in the earthquake zone of Hebei Plain and Lubei Plain, the underground vibration can be effectively buffered by groundwater to the maximum extent.
