weekend, jump The tourists are weave at the edge of the spring. Qilu Evening News and Qilu one point reporter Zhou Qing first Yangchun in March has always been the fastest spring water level drop, although the water level has also dropped a lot this year, but because of the thick water base last year and the recent supply of rain water, the water level of the spring has always survived the first ridge of the year. In the future, the spring will rise and fall and remain stable. If we can get through the second roads in June, spring will continue to surge this year.
the water level in Baotu Spring is more than half a meter higher than
according to the data of the Ji'nan Water Conservancy Bureau. The water level of Baotu Spring is 28 meters, and the water level of the black tiger spring is 27.94 meters. Although from the beginning of March to now, the water level of Baotu Spring has declined continuously to 43 centimeters, but with the recent spring rain of patter, the water level of Baotu Spring will be basically stable, which means that the water level of the spring has passed through the first camp of this year.
with the increase of temperature and the increase of water consumption in spring irrigation, every spring, especially in March, is the month when the water level of the spring falls sharply. The reporter has done statistics, the water level of the Baotu Spring in the last three years is generally about 30 cm. According to the calendar year's water level statistics, the Baotu Spring water level can be down to about 50 centimeters in the spring.
according to the water level data of the past years, after entering four and May, the spring water level rises and falls steadily under the influence of precipitation.
due to more rainfall in autumn last year, the bottom of the spring became thicker. In addition, there was no shortage of spring rainfall this year, and the water level of the spring was much higher than in previous years.
according to the data of the Ji'nan Water Conservancy Bureau, the total precipitation in the city has averaged 53.7 millimeters since this year. It is 14.1 millimeters more than 39.6 millimeters in the same period of the year. It is 35.6% more than 17 millimeters more than 36.7 millimeters in the same period of last year, and 46.3% more. The urban area is 60.5 mm, Pingyin 51.9 mm, Changqing 56.1 mm, Licheng 60.6 mm, Zhangqiu 45 mm, Jiyang 59.1 mm, Shanghe 42.5 mm.
the reporter found that the water level of Baotu Spring was 27.44 meters in the same period last year, the water level of the black tiger spring was 27.39 meters in 2015 and the water level of Baotu Spring was 27.73 meters in the same period in 2015, and the water level of the black tiger spring was 27.66 meters. That is to say, compared with the previous two years, the water level of Baotu Spring is 56 centimeters and 27 centimeters higher this year.
in June, if the water level is stable
spring water can be annual
in the four great springs of Ji'nan, the highest is the black tiger spring group. According to past experience, after the water level is less than 28 meters, the agate spring belonging to the black tiger spring group will be the first spring pool to stop running water. If the drought continues, then the black tiger spring will be affected.
14, the reporter saw in the scenic area around the city, the agate spring flow still showed a water column, flowing to the moat, and there was no phenomenon of cut-off.
reporter found that, in fact, the agate spring seems to be a common phenomenon in the past years. For example, in 2015, the agate spring has been disconnected four times. From 2010, the agate spring stopped to the moat overflow.
is this year's agate spring well enough to achieve uninterrupted water throughout the year? This conclusion is not very good. At present in the 28 meters water springs can achieve stabilized bullish, will have to see the next rain to suck.
28 meters is the orange warning line of Baotu Spring. Because of the drought in 2015, the water level of the spring was low. Last year, the water level of the Baotu Spring dropped to less than 28 meters in January 24th. It was not until after the flood season began in July that the water level gradually increased. After nearly 6 months, the water level rose to more than 28 meters.
compared to last year, the water level of Baotu Spring is relatively optimistic this year. However, it has survived the spring, and by June, the water level of the spring will experience another influence.
looking at the history of Baotu Spring's water level, we can see that in many years, the lowest water level of Baotu Spring appeared in June. For example, last year, the water level of Baotu Spring dropped to 27.17 meters in June 14th, the lowest value in the whole year, and only 16 centimeters from the stop spray.
even in June, the water level of the spring decreased greatly. There is no need to worry too much. This is the natural manifestation of the rising and falling of the spring water level in a year. As long as the flood season is approaching this year and the rainfall reaches the average level in the past years, the continuous flood of spring water will become a foregone conclusion.
