The formation of Jinan springs

Jinan is located in the central and western part of Shandong Province, at the junction of the low mountains and hills in central and southern Shandong and the alluvial plain in northwest Shandong. The terrain is high in the south and low in the north. The terrain is complex and diverse, and can be roughly divided into three zones: the yellow zone in the north, the piedmont plain zone in the middle, and the hilly and mountainous zone in the south.

The reason for the large number of springs in Jinan is due to its unique topography and geological structure. There is a layer of limestone underground in Jinan. The rock layer itself is not very tightly combined, forming pores, cracks and caves, which can store and transport groundwater.

A large amount of groundwater flows along the limestone formations in the southern mountains of Jinan. After reaching Jinan, it is blocked by the tightly organized magma rocks in the northern suburbs. It cannot move forward and accumulates more and more.

In the end, the pores and cracks in the ground became their excretion doors. A large amount of groundwater stored here gushes out of the ground along these cracks with strong pressure, and natural springs appear. These springs are of various shapes, some are rolling white waves, like silver flowers and jade stamens, and some are crystal clear and moist, like bright pearls. Yingluo.

The division of springs in Jinan

There are hundreds of springs gushing in Jinan City, and the world's best spring scenic area is home to the prestigious Baotu Spring, Black Tiger Spring, Wulongtan and Pearl Spring. There are seventy-two famous springs in Jinan. In fact, there are more than 72 springs in Jinan. There are more than a hundred large and small spring pools in the urban area alone. The four major spring groups are its main components, and the others are "secluded" in Jinan's jurisdiction. elsewhere.

Jinan’s Seventy-Two Famous Springs divides the top ten spring groups from the perspective of geography and tourism. They are Baotu Spring Group, Black Tiger Spring Group, Pearl Spring Group, Wulongtan Spring Group, Baiquan Spring Group, Baimai Spring Group, Colorful Stone Yuhe Spring Group, Liubu Yong Spring Group, Wande Spring Group Kasaya spring group and Pingyin Hongfan pool spring group.

The ten major spring groups all belong to the broad "Jinan Spring Group", and are divided from east to west into Mingshui Spring Area, Baiquan Spring Area, Quancheng Red, Quancheng Green, Jinan Spring Area, and Changxiao Spring Area. Four spring areas.

The most representative spring group in Jinan is the Baotu Spring Group. Liubu and Yongquan Spring Groups and Wande Kasaya Spring Group belong to the Baotu Spring Area. Each small spring has no hydraulic connection with each other, and there is no hydraulic connection between the two small spring groups, but these springs seep along the river.

The Baiquan spring group represented by Baiquan also has the same water source and the same supply area. Its supply area is called "Baiquan Spring Area". The Colorful Stone Jade River Spring Group is located in the recharge area of ??the Baiquan Spring Group, that is, the Baiquan Spring Area. These springs seep along the river and eventually flow to the Baiquan Spring Group. Due to extensive mining, the Baiquan Spring Group has been cut off all year round.

The supply area of ??the Mingshui Spring Group represented by Baimai Spring is called "Mingshui Spring Area". This spring area spans Zibo and Jinan. Its type is exactly the same as Baotu Spring and Baiquan Spring Group and Spring Area. They are both among the three major spring groups and three major spring areas in Jinan City.

The Pingyin Hongfan Spring Group, represented by Hongfanchi, is located south of Changcheng Ridge. Surface water and underground water form their own system, all flowing to the Dawen River. The type of the spring group is the same as that of the Licheng Caishi Yuhe Spring Group. The Hongfan Spring water does not flow directly to the Dawen River, but leaks along the way to supply the water source of Kongcun Xiaozhi, which is also the water source of Shiheng Power Plant.
