21 days, the reporter learned from the Ji'nan municipal government website, Ji'nan Water Conservancy Bureau, agriculture bureau, forestry bureau and other units into the "government supervision over the face", accept the public to mention Ask for comments. Every spring is the key period to protect the spring. It is understood that rainfall in Ji'nan is still relatively low this year, 60% less than the same period last year.
20 days, the Baotu Spring water level fell through the 28.15 meter yellow warning line, ending the high water level that has lasted for about 8 months since July 23, 2016. This has also worried the people of Ji'nan. In the course of politics, a citizen raised the question of protecting springs.
Li Guanghua, deputy director of Ji'nan Water Conservancy Bureau, said that the main reason for the continuous decline of the spring water level is mainly rainfall. "This year, the rainfall is only 11.5 millimeters, 40% less than the same period of the year, less than 60.8% last year, that is, this year's rainfall is very small." In addition, spring irrigation is also a major reason for the decline of spring water level. Li Guanghua said that during the spring irrigation period, the underground water level of the surrounding rural areas is also declining, which has a certain effect on the spring water.
when the water level is below 28.15 meters, as the water level continues to fall slowly, the landscape will gradually be discounted. Li Guanghua said that in order to ensure the spring water spewing, the water conservancy bureau also adopted a number of measures.
"first of all, we need to strengthen water resources scheduling and increase the amount of water supplied by manpower." Li Guanghua said that this area mainly depends on the two major reservoirs in the mountain area, one is the hushushan reservoir, the other is the Jinxiu reservoir. There are 57 million cubic meters of water in the hushushan reservoir. Jinxiu Chuan is in 38 million cubic meters plus 85 million cubic meters. At present, the two reservoirs make up 250 thousand tons of water to the urban area every day. Among them, the hushushan reservoir supplies 150 thousand tons of water every day and 100 thousand tons of Jinxiu Chuan reservoir every day. Ji'nan is also strengthening the replacement of water sources and minimizing the exploitation of underground water. Using the East Lian water supply project, the water of the magpie mountain reservoir is transferred to the East, the water supply is supplied to large enterprises and the groundwater is not exploited. The amount of water supplied in one day is more than 70 thousand tons. In the aspect of agricultural water use, the Yellow River water should be used to replace groundwater. There are a total of 11 the Yellow River gates in Ji'nan, and 6 pumping stations are being built. 2 new sites will be built this year, and 3 new sites will be built next year.
