Quancheng information

Quancheng is another name of Jinan City, Shandong Province. Jinan is famous for its numerous springs and beautiful scenery. According to statistics, there are four spring areas, ten spring groups and 733 natural springs, which are rare in cities at home and abroad. This is a unique natural karst spring museum. In addition to "Spring City", Jinan is often called "Spring Capital". The springs in Jinan are not only numerous, but also varied in shape and colorful, some spewing out, some waterfall-shaped, and some lake-bay-shaped. Many cool and sweet springs gush from the underground of the city and flow into rivers and lakes. In the peak season, in the spring-intensive areas, there are beautiful scenery of "every spring, every weeping willow" and "crystal stone in the stream". As early as the Song Dynasty, Ceng Gong, a writer, commented: "Qiduo Ganquan is the best in the world", and Yu Qin, a geographer in the Yuan Dynasty, also praised: "Jinan's mountains and rivers are the first, and springs are the first in the world." The clear and sweet spring water is the blood of Jinan, which endows the city with exquisite temperament and vigorous vitality. At the same time, Jinan's urban development, historical evolution and folk customs are also closely related to spring water, forming a unique spring water culture.

Edit the formation of Jinan Spring.

Jinan is located in the middle and west of Shandong Province, at the junction of low mountains and hills in central and southern Shandong and alluvial plains in northwest Shandong, with high terrain in the south and low terrain in the north. The terrain is complex and diverse, which can be roughly divided into three zones; The Yellow River belt in the north, the piedmont plain belt in the middle and the hilly and mountainous belt in the south.

Jinan has many springs because of its unique topographical and geological structure. There is a layer of limestone underground in Jinan, which is not tightly combined, forming pores, cracks and caves, which can store and transport groundwater. A large amount of groundwater in the southern mountain range of Jinan undercurrents along limestone strata, and is blocked by closely organized magmatic rocks in the northern suburbs after reaching Jinan. If you can't move forward, you will accumulate more and more. Eventually, underground pores and cracks become the gates for their discharge. A large amount of groundwater trapped here gushes out of the ground along these cracks with strong pressure, so there is natural spring water. These springs have different shapes, some of which are white waves rolling, like silver flowers and jade flowers, and some are crystal clear and moist, like pearl garlands.

Edit the division of Jinan Springs in this section.

There are hundreds of springs in Jinan, and there are four famous spring groups: Baotu Spring, Black Tiger Spring, Wulongtan Spring and Pearl Spring. According to seventy-two famous springs, there are actually more than 72 springs in Jinan, and there are more than 100 large Koizumi pools in the urban area alone. Siquan Group is the main component, while others live in seclusion in other places within the jurisdiction of Jinan. While re-examining 72 famous springs, Jinan city has divided ten spring groups from the perspective of geography and tourism. They are nights in downtown Jinan.

Baotu Spring Group, Black Tiger Spring Group, Pearl Spring Group, Wulongtan Spring Group and Bai Quan Spring Group in the eastern suburb of Jinan, Zhangqiu Mingshui Baimai Spring Group, Licheng Caishihe Spring Group, Licheng Liubu Yongquan Group, Changqing Wande Cassock Spring Group and Pingyin Hongfan Chiquan Group outside the city. The top ten spring groups all belong to the generalized "Jinan Spring Group", which is divided into Mingshui Spring Area, Baiquan Spring Area, Jinan Spring Area and Changxiaoquan Area from east to west. From the hydrogeologic point of view, the "four major spring groups" in the urban area represented by Baotu Spring are actually a spring group, belonging to Jinan Spring Group in a narrow sense. They have the same water source and the same recharge area, which are collectively called "Baotu Spring Group" and their recharge area is called "Baotu Spring Area". Liubu, Yongquan group Wande cassock spring group is located in the supply area of the "four major spring groups" in the urban area, namely Baotu Spring area. There is no hydraulic connection between each Koizumi group and between two Koizumi groups, but these springs leak along the river and eventually flow to urban springs. In addition to "Jinan Spring Group", Baiquan Spring Group in the eastern suburb of Jinan, represented by Baiquan, is also the same water source and the same recharge area, and its recharge area is called "Baiquan Spring Area". Cai's Yuhe Spring Group is located in the recharge area of Baiquan Spring Group, that is, Baiquan Spring Area. These springs leak along the river and eventually flow to Baiquan Spring Jinan Avenue of Stars.

Group. Due to large-scale mining, Baiquan Spring Group has been cut off all the year round. The recharge area of Zhangqiu Mingshui Spring Group, represented by Baimai Spring, is called Mingshui Spring Area. This spring area spans Zibo and Zhangqiu, and its types are exactly the same as Baotu Spring, Baiquan Spring Group and Spring Area, belonging to the three major spring groups and spring areas in Jinan. Pingyin hongfenquan group, represented by hongfenchi, is located in the south of Changchengling. Surface water and groundwater are self-contained, and both flow to Dawen River. Its spring group type is the same as Yuhe Spring Group in Licheng Quarry. Hongfan spring water does not flow directly to Dawen River, but leaks along the way to supplement the water source of Kongcun-Xiao Zhi, that is, the water source of Shi Heng Power Plant.
