When describing the Baotu Spring in Lao Can's Travels in the Qing Dynasty, Liu Eu wrote, "There are three large springs in the middle of the pool, which rises from the bottom of the pool and rises to the water surface two to three feet high ..." However, the reporter was in Baotu on the 3rd The spring area found that the water surface of the "three strands of springs" was relatively calm, and there was a slight splash of water, which did not stop the gushing, but it was already difficult to find the "water wheel is rushing" scene. Shuyuquan, Jinxianquan, Woniuquan, Huanghuaquan and other springs in the scenic spot are difficult to see with the naked eye. The water level of the spring is significantly lower than the traces left by the previous water level.
Affected by the new crown pneumonia epidemic, the "First Spring in the World" scenic area was closed for business during the Lunar New Year Festival until February 27th. It reopened to welcome guests during the "May Day" holiday. The number of tourists visiting Baotu Spring on that day was not large, which was significantly less than the previous May Day holiday.
"Spring City" Jinan has the reputation of "springs are the best in the world". There are more than 640 famous springs in the area, the most famous of which are 72. Among them, the Baotu Spring, where the emperor Qianlong of the Qing Dynasty in China was named "the first spring in the world" The most prestigious. The groundwater level of Baotu Springs is also often regarded as the scale of the climate and hydrological environment in northern China.

The most direct factor that affects spring spouting is rainfall. The steaming weather with high temperature and little rain is the "natural enemy" of the springs. October to June each year is the dry season of Jinan springs.
A reporter consulted the official water level data of the Jinan Urban and Rural Water Affairs Bureau and found that the water level was 27.80 meters on the same day in 2019, 27.81 meters in 2018, and 27.90 meters in 2017. They were below the 28-meter orange warning line for three consecutive years.
The staff of Jinan Urban and Rural Water Affairs Bureau said that the groundwater level of Baotu Spring was in a state of decline during the dry season, and it was normal to fall below the warning line. At present, Jinan has adopted more ecological replenishment sources and ecological restoration methods in keeping with the spring, conserving the water and soil in the spring water replenishment area in the southern mountain area, and restoring some strong leakage zones.

According to the "Jinan City Emergency Plan for Maintaining Spring Water Spilling", when the groundwater level of Baotu Spring drops to 27.60 meters, Jinan City will issue a red warning and start the first-level emergency plan, and all departments shall adopt water source replacement, control mining restriction, and return Measures such as filling sources.
In May, northern China opened a crazy "steaming and roasting" mode, which made social media "bring salt for yourself", "me and barbecue only a pinch of cumin" and "sweat like rain". "The hot spring spurt is weak in high-temperature and low-rain weather, which also shows that the spring spout in Jinan is a natural phenomenon." Wang Zhe, a tourist who visited Baotu Spring, said that this year's "May Day" is indeed hotter than in previous years. .
According to the weather forecast, it is expected that Shandong will be mainly sunny and fine throughout the May Day, but there is some rain on the road. It is expected that there may be rainfall in Jinan on May 9 and 10, and the amount of rain is light. Rainfall will alleviate the high temperature in Jinan, but according to the amount of rain, it may not be of much help to the spring water. Jinan Yiquan Spring is about to enter this year's largest "baking test" period.
