Zhangqiu because of many springs, water Known for its abundance and abundance, it is known as "Koizumi city". How to make Zhangqiu's hundred spring continue to spew? 14, Zhangqiu District invited the famous experts from Shandong and Zhangqiu to work in Zhangqiu. The reporter learned that Zhangqiu city is currently planning to protect the source project of spring water protection (phase I), and draw lessons from the recharge source of the Baotu Spring in Ji'nan to build a three-dimensional filling source system, and strive to achieve the continuous sprays of the spring water.

100 pulse springs mainly depend on the day "drinking water"
the spray is mainly affected by the precipitation of
14 days, the water level of Zhangqiu hundred pulse spring is 58.83 meters, and it has been reduced by 2 centimeters more than the 13 day. Since entering spring, the water level of many springs in Zhangqiu district such as Bai Mai Quan, Mo Quan and meihua spring has been falling down. Although the water level of the 100 mile spring is 57.83 meters away, there is still a long way to go.
how to keep Zhangqiu's hundred pulse springs continuously and fully realize the use of spring water to improve the living environment of Zhangqiu citizens? On the 14 day, Zhangqiu District invited Professor Lin Xueyu of the Chinese Academy of Sciences, Dr. Shi Jian of the Chinese Geological Society, vice president of the Chinese Academy of geological Sciences, he Qingcheng Bo, deputy director and general of the Bureau of Geology and geology of Shandong province. Cheng Shi Xu Junxiang and Yang Lizhi, director of the Institute of hydrogeology and environmental geology of Shandong Institute of geological survey, and other experts came to recruit and protect Zhangqiu's spring water.
according to the head of Zhangqiu Bao Quan department, there are as many as 25 famous spring spots in Zhangqiu. According to many years geological survey and survey research, the hundred veins spring water comes from the precipitation infiltration recharge in the southeast of Zhangqiu and the limestone mountain area in southwest Zibo. The area of the replenishment area is 355 square kilometers (250 square kilometers in Zhangqiu and 105 square kilometers in Zibo). The
spring area is high in the south, low in the north and high in the East and low in the West. In the southeastern part of the spring area, the southeastern part of the spring area is collected by the infiltration of atmospheric precipitation, which is collected in the direction of the clear water, the west side is blocked by the Wen Zu fault and the north side is blocked by the impermeable layer of the coal field, and the surface is gushed out in the fractured zone along the fault zone in the Ming water, forming a hundred pulse spring group.
the average annual rainfall in Zhangqiu spring area is 613 millimeters. The 100 pulse spring water is characterized by a typical rain source. The change rule of water level in the hundred mile spring started from 6 and July and reached the highest in November.
4 times in less than 25 years and 4 times
low risk
it is introduced that in order to keep the continuous sprays of the 100 pulse spring water, the Zhangqiu district decided to shut down all coal mines and clay mines in 2015 and directly reduce the daily drainage of 22 thousand parties in the spring area. In recent years, Zhangqiu district has totally closed 110 wells of self provided water wells in urban areas. As the main source of water supply in the urban area, he set water plant will also be completely shut down this year.
over the past few years, the annual groundwater exploitation in spring area has been maintained at more than 67 million cubic meters. Among them, the groundwater pumping capacity accounts for 7 of the spring area in Zibo. Due to the common influence of climate drought and the overexploitation of groundwater in spring area, the fluctuation of the water level of the spring spring is increased, and the time of breaking out and stopping in the dry period has a tendency to expand.
it is reported that since the system water level data in 1993, Zhangqiu's hundred pulse springs have been disconnected four times: 1993, 1999, 2001 to 2003, 2014 to 2016, respectively, 70 days, 527 days, 909 days and 740 days respectively.
according to the relevant person in charge of Zhangqiu District, spring is the soul of Zhangqiu. Spring has irreplaceable brand resource value and social influence in Zhangqiu. In order to keep the spring water continuously spewing, Zhangqiu district has commissioned relevant units to work out a plan for the protection and supplement of spring water (phase I).
the reporter saw this plan, Zhangqiu district will learn from the successful experience of Ji'nan Baoquan, in the urban Ming water fracture zone, the small Dongshan white spring ecological wetland, and the overlap of the landscape river.
to create 7 urban water systems
is both the landscape and the source
according to the scheme, Zhangqiu has planned a total of 7 water systems, such as the ten East Road water system, Xiushui Street and so on. On the one hand, these rivers will form the murmur of the roadside spring, and will provide water for the source project of Zhangqiu.
according to the experts of the Shandong Institute of geological and mineral exploration, the recharge of the 100 pulse spring water mainly depends on the breakage channel of some north and south direction. The recharge area is small and the flow change is large. "In the extreme drought conditions, it is easy to break the flow." But these characteristics also make it more suitable for the artificial supplement. "After the main artificial channels are supplementing the source, the water of the supplement can quickly reach the drain area of the spring area, and keep the continuous spring water gushing".
at the meeting that day, experts from the state and province affirmed the relevant supplementary source plan. Relevant experts also suggested that Zhangqiu district should make relevant plans for recharging and supplement, and do a good job of data collection and calculation at the later stage, so as to achieve accurate protection of springs.
according to the relevant person in charge of Zhangqiu District, Zhangqiu district will also do a good job of the first look and use of spring water on the basis of ensuring the continuous spring flood. In Zhangqiu, the four major upgrading projects of transportation, ecology, industry and town are put forward. The core of ecological promotion and urban promotion is to protect the spring water and build the ecological cultural symbol area of the spring water.
