Information about Baotu Spring and Daming Lake

1. Baotu Spring, also known as Threshold Spring, is the source of Longshui. The three springs are closely arranged in a line, which produces a chorus with great momentum. Therefore, it was called "the first spring" by Emperor Qianlong. It is the first of 72 springs in Jinan and one of the three major scenic spots in Jinan.

Baotu Spring is located in the southwest corner of the old city of Jinan and the westernmost end of the south moat. Baotu Spring Park is located in the west of quancheng square and south of Wulongtan Park. The north gate of the park faces the commercial street "quancheng road", and the moat meets the spring water in the park. Because there are three springs in the center of the same spring pool. There is Guanlan Pavilion on the west bank of Quanchi, and there is Shun Fei E Ying Temple on the north bank.

Baotu Spring is a typical artesian well in geography. The causes are roughly the same. The formation condition of Yongquan well is valley topography. Groundwater flows along the rock stratum to the lower part, and the cracks in the lower part rise and gush out under high water pressure.

The deep underground layer of Jinan is composed of metamorphic granite, and the upper layer is calcareous sedimentary rock. Sedimentary rocks are prone to water seepage, and granite prevents groundwater from continuing to penetrate downwards. The south of Jinan is the northernmost part of Mount Tai, and the north is the famous Yellow River on the ground. This has formed a relatively low basin structure in the urban area. Precipitation seeps into the underground river from the southern mountainous area and collects under the urban area to generate water pressure. The main spring group is the outlet of spring water leakage.

Daming Lake is located in the north of Jinan, the capital of Shandong Province. Now it is one of the three famous scenic spots in Jinan, and the other two scenic spots are Baotu Spring and Qianfo Mountain. It covers an area of 865,438+10,000 square meters, and the lake area is about 460,000 square meters, accounting for about one third of the old city. At the gate of Daming Lake Park, there is a "Daming Lake" plaque inscribed by Guo Moruo, and the door is headed by a couplet, "Lotus flowers on all sides and willows on three sides, a city with mountains and a half city with lakes".

Daming Lake, with a long history, is also famous for its cultural landscape. Many architectural landscapes have been built to commemorate the achievements and whereabouts of the ancients, such as Lixia Pavilion, Xiayue Pavilion, Tiegong Temple, Xiaocanglang, Arctic Pavilion, Huibo Building, Nanfeng Temple, Yuanyuan Temple and Jiaxuan Temple. , which attracted the literati of past dynasties to lament and recite.

These include Li Bai in Tang Dynasty, Ceng Gong and Su Shi in Song Dynasty, Yuan Haowen and Zhang in Jin and Yuan Dynasties, He and Wang Xiangchun in Ming Dynasty, Wang Shizhen and Pu Songling in Qing Dynasty. The ancient buildings in Daming Lake Park are cultural relics protection units in Shandong Province.

Extended data:

The four mysteries of Daming Lake have a long history. Wang Xiangchun, a left-wing poet in the late Ming Dynasty, recorded in detail in his book Daming Lake in Yin Qi-"The lake is in the city, but there is nothing in the house. The difference is that the constant rain does not rise, and the long drought does not dry up; As for snakes not appearing and frogs not singing, that's different. " Later, this article was included in Licheng County Records by the Qing people, which should be an earlier written record about the four eccentrics of Huming Lake.

This is the well-known "four eccentrics" in Daming Lake, Jinan-frogs don't croak, snakes are hard to find, long droughts don't fall, and long rains don't rise.

1, frogs don't bark: Up to now, no one can find a reasonable answer to the so-called "frogs don't bark".

2. Snakes are hard to find: The so-called "snakes are hard to find" is because there are many waterfowl in Daming Lake, and it is difficult for snakes to survive in it.

3. Persistent drought: The so-called "persistent drought" is because the bottom of Daming Lake is fine igneous rock, which makes the spring water flowing into the lake unable to be discharged.

4, long rain does not rise: the so-called "long rain does not rise" is because there are many outlets in Daming Lake. When the water rises, it will naturally flow out.
