the first day of Huang Zhongming's May 1 holiday, Ji'nan is "bright".
the beginning of this year, this is almost dry, since the implementation of ecological water diversion in early February, the Jinxiu Sichuan reservoir has accumulated 3 million 40 thousand cubic meters of water to the Mencian reservoir. Now the water is replenished to the downstream of the Daxin River, which can not only make use of the river for ecological supplement, but also improve the landscape of the river and the ecological environment of the area of the Olympic body. Tang Ruiqin, director of the propaganda office of the Municipal Water Conservancy Bureau, said that the above is only part of the five storehouse connection project. The project is an important part of the south to North Water Transfer Project in Ji'nan, and it is also an important content of the water network planning of "six horizontal vertical eight longitudinal and one circling spring city" in the city. The
project uses the surface water source of two reservoirs in the reservoir of Hui Shan and Jinxiu Sichuan, as well as the water and water resources of the Yellow River water and Changjiang River. Through the transformation and new water supply lines, the five reservoir connected and multiple water sources joint dispatching, to the Southern suburb and the watershed 2 waterworks and the Xinglong, the slurry spring, the Mencius 3 reservoir and the Xingji River, the Quan Fu River and the Hongshan 4 rivers in the river and the Daxin River replenish water, and at the same time make ecological water supplement to the strong seepage zones of 8 springs, such as Shaoxing Zhun village and dacen gully, so as to form the connected pattern of "5248" water system of 5 reservoirs, 2 waterworks, 4 urban waterways and 8 strong seepage zones along the line.
the project was started in October 2014 to build the basic construction of the main project in December 2015, to achieve the daily water supply of 150 thousand cubic meters in April 2016, to complete the project phase test water, to optimize the allocation of water resources and improve the efficiency of the urban ecological water network. Since February 22, 2017, the project began to carry out a comprehensive ecological source, which has played a very important role in the continuous spewing of the support spring group and the improvement of the ecological landscape environment of the river. The "five brothers" hold together, and it is of great significance for Ji'nan to "eat enough food" and "five libraries connect".
realized the joint operation of multiple water sources and optimized the allocation of water resources. On the one hand, the regional distribution of water resources in our city has been uneven for many years, and the surface water resources in the south are the main ones. The first phase of the south to North Water Diversion Project and the connecting project between Tianshan irrigation district and the main channel of the river were completed and the water supply for the southern part of the Yangtze River and the Yellow River was brought to the south. This means that the only large reservoir in Ji'nan can get rid of "stay in heaven" and have many water sources, such as the Yellow River water, Yangtze River water, local surface water, ground water, unconventional water and so on. On the other hand, the 3 reservoirs of Xing long, Su Shui Quan and Meng Jia belong to small reservoirs with little regulating ability. After connecting now, both the hushushan reservoir and the Jinxiu Chuan reservoir can supply water to them, so that they can "have enough to eat" all the year round. "To put it simply, these five brothers are now working together in a concerted effort to connect each other. Urban water supply, groundwater replacement, recirculation supplement and urban ecological water use have more reliable water source protection.
, "Tang Ruiqin said. An ecological water network has been constructed to create a green water ecological corridor. In addition to the reservoir, there are rivers. The 4 urban river courses of Xingji River, Quan Fuhe River, Hong Shanxi and Daxin River are replenished without water source during the non flood season. Now, in the low water period, the ecological water network can increase the reservoir water volume along the reservoir, keep the high water level and the large water surface of the reservoir, and improve the ecological climate of the reservoir area. At the same time, the replenishment cycle is transformed from a short-term supplement to a year-round source, which will further enhance the landscape of the river, improve the ecological environment of the water, and create a green water corridor.
multi-source and multi-point leakage supplement source, and help spring group continuous spewing. There are 8 key seepage zones in the Ji'nan spring area, which are distributed along five reservoir connected projects. Through the positive and reverse water transfer functions of the five library connected projects, the water supply in the strong seepage zones of the 8 springs, such as the Dali gully and the watershed, and so on, can be filled in according to the actual situation of the groundwater level.
