"six cross connect eight longitudinal, one surround spring city"
the backbone of the city water network is "six horizontal eight longitudinal, one circling spring city".
"six horizontal" refers to the 4 large rivers running through the whole city of the Yellow River, the Xiaoqing River, the Apostle River, the Dehui New River River and the water diversion canal of the south to North Water Diversion Project and the East Union water supply project. The "eight vertical" refers to 6 medium-sized rivers, Tianshan and Xing Jiadu water diversion channels from Shahe, Yufu River, Juye River, embroidery River, great Si River and Shang Zhonghe river. "A surround spring city" refers to the 3 reservoir in the main city, including the 4 mountain reservoirs and the Yuqing lake, magpie mountain and East Lake. Among them, the Yellow River is connected with Shahe, Yufu River and Tian Shan, Xing Jiadu diversion channel, Yuqing lake and magpie mountain reservoir, and the Xiaoqing River is connected with the Juye River, the embroidery River, Yufu River and the water diversion canal in the south to North Water Transfer; the river is connected with the Great Temple River and the middle river; Dehui New River is connected with the Shang Zhonghe River and the Apostle River; and the south to north water transfer is transferred to the water. The canal is connected with Yuqinghu, East Lake reservoir and Xiaoqing River, and the East joint water supply project is connected with magpie mountain, Du Zhang, East Lake, and wolf cat landscape library, and the "six horizontal and eight longitudinal" forms constitute a grid layout. Between the yuhushan and Jinxiu Chuan reservoir, the river is connected through the river, and the seven reservoirs are connected through the pipes, which are connected by the pipes between the yuhushan, Yuqing lake, magpie mountain, Du Zhang, the wolf Cat Mountain and the East Lake reservoir.
the Yellow River, the Xiaoqing River, the Apostle River, the Dehui New River and the south to north water diversion channel are also the main structure of the provincial water network. East Lake is the storage reservoir of the south to North Water Diversion Project, and the water network of the city is an organic part of the Shandong water network. It is located in the "one ring" of Nanshan District in the "two ring" of the Shandong water network. And the "area" in the northwest plain of Lu.

formation of "upper storage, medium and sparse, discharge, appropriate flood diversion and flood detention" overall layout of
key projects:
three large water network system, 12 categories and 41 key points Project
key project is the basic support of water network construction and connectivity. The three major water network system mainly includes six major projects, including flood control and waterlogging, urban and rural water supply, water system ecology, unconventional water utilization, spring water use and water supply, water conservancy information and so on. There are 12 categories and 41 items. After the completion of the project, it will significantly improve the level of flood control and waterlogging in the city, ensure the safety of urban and rural water supply and optimize the ecological environment of the water system, and constitute the backbone of the water network of "six horizontal eight longitudinal and one surrounding spring city".
at present, the flood control project of the city includes 4 large rivers, 15 medium-sized rivers and Huashan lakes in the Yellow River, Xiaoqing River and so on, and 186 large and medium and small reservoirs. These flood control projects were built in the last six and 70s of last century, and played an important role in flood control, water logging and irrigation for many years. However, due to low engineering construction standards, coupled with engineering aging and serious degradation, it brings some hidden troubles to operation management. The flood control and waterlogging network system of
will mainly improve the existing flood control system, with the basin as the unit, the reservoir and the pond as the storage node, the lake as the flood storage and flood area, the river as the discharge carrier, to realize the connection of the river, Lake and pond, the storage and adjustment of the stagnation and discharge, and to improve the ability of flood control, flood control and rain flood utilization in an all-round way.
flood prevention and waterlogging is divided into 4 types of 9 projects: river regulation, reservoir sluice reinforcement and flood detention area construction. Since 2008, 6 large and medium-sized reservoirs in the city have been included in the national investment management and reinforcement plan of the reservoir. In addition, 126 small and sick reservoirs have been strengthened and strengthened in our city. Here, a total of 790 million yuan has been invested in the reinforcement project of large and medium sized reservoirs in our city, which fundamentally solves the problem of low standard of reservoir construction and the operation of diseases. In 2012, 4 medium-sized reservoirs, such as wolves and Cat Mountain, are planned to be strengthened and reinforced, and 139 small reservoirs in Pingyin County, which are included in the central plan, and 139 ponds and reinforcement projects in the 6 counties (cities) of Zhangqiu, have been completed to promote the improvement of the small reservoirs. In addition, flood control and waterlogging removal projects such as flood diversion and comprehensive regulation of the river have been progressing smoothly, and the construction of water network has been fully started.
the next step, the construction of flood control and waterlogging network system will be based on the characteristics of the terrain and terrain of the South high and north of Ji'nan, and perfect the flood control system according to the principle of "upper storage, middle and sparse, lower row, proper flood diversion and flood detention". "Shangyu" mainly refers to the upstream reservoirs and ponds to hold up floods, and the southern mountainous areas to strengthen soil and water conservation, increase rainfall infiltration and reduce surface runoff. The key river courses are implemented according to flood control standards, and the reservoirs and reservoirs are not reinforced. "Zhong Shu" means dredging upstream flood through the tributaries of the Yellow River river system and Xiaoqing River system, and strengthening the development and utilization of rainwater resources at the same time. The central hilly area should be combined with dredging and dredging to increase drainage capacity. Xiaoqing River and the Yellow River use low-lying areas to restore and build flood storage and detention areas. "Discharge" means draining flood through the main stream of the Yellow River and the main stream of Xiaoqing River. "Appropriate flood diversion and flood detention" mainly refers to the implementation of the La Shan flood diversion project, and the Xiaoli family and Huashan Lake flood storage area planned by the Xiaqing River main stream to share the Xiaoqing River flood in order to alleviate the flood control pressure downstream.
protection of urban and rural water supply safety
gradual realization of rural water supply urbanization and urban and rural water supply integration
urban and rural water supply network system based on existing irrigation and drainage system. In order to improve the regulation and control of water resources and ensure the supply of water resources, the channels should be transported through pipelines, connected with rivers, reservoirs and channels, and with multiple water sources. According to the basic structure of the project, the water supply and water network consists of three parts: urban water supply, rural water supply and irrigation and drainage. A total of 18 key projects will be implemented. It will be completed before the flood season this year, and will further improve the use of water resources and the quality of water. The project will be completed by the end of this year, and 100 thousand cubic meters of groundwater will be supplied to the urban area every day after operation. Fengyuan lake water storehouse has been built. It is expected to be put into use by the end of next year. At that time, 200 thousand people in 5 villages and towns in Shanghe county will say goodbye to bitter salt water, and the integration rate of water supply in urban and rural areas of the county reaches 100%. The next step is to gradually realize the urbanization of rural water supply, the integration of urban and rural water supply, improve the quality of drinking water, and 85% of the total cultivated land in the city will be included in the scope of irrigation area construction.
urban water supply
optimal water supply and water supply
the main city water supply is the urban water supply project. The city's current urban water supply capacity is 2 billion 444 million cubic meters, of which more than 80% of the water sources come from the Yellow River. Embroidery Sichuan, north of magpie mountain, West jade Qing Lake, east of the wolf cat landscape library, the Yellow River water, surface water mainly, with groundwater as the auxiliary, multi water combined water supply pattern, in the future, the East water supply will gradually replace the eastern industrial ground water for the residents to provide high quality water to provide protection. As an important urban infrastructure, urban water supply should be adapted to the development of the city. The water network construction will rationally allocate the water diversion and water diversion according to the current water supply pattern in Ji'nan, improve the water source support capacity through the regional connected engineering, make full use of the spring water resources, create the brand of the spring water, actively promote the water supply of the divided quality and promote the public. Quality of drinking water. The "five water" should be used as a whole to protect the "three generation" water, and ultimately achieve "piecewise water supply, joint operation, excellent water quality and quality water supply".
Yuqing lake reservoir mainly supplies water for life, production and ecology. The water supply scope is west city zone and Ji'nan economic development zone. The main water supply of the Queshan reservoir is the life and production water of Binhe new area and Tianqiao Chemical Industrial Park. Through the supply of water supply in the eastern New Area of the main city, the the Yellow River water of the magpie mountain reservoir, the local surface water and the Yangtze River water from the south to the north can be connected through the pipeline to provide reliable production and ecological water to the east area, to replace a large amount of groundwater and to design the water supply capacity of 244 thousand tons / day. At present, about 54 million 800 thousand tons of water supply has been accumulated, which has made positive contributions to the residents to drink high-quality water and save water and water. East Lake reservoir mainly supplies industrial water in eastern urban area. The hushushan reservoir is used as the source of domestic water, the ecological water supply source in the spring area and the ecological water source for the urban river. Jinxiu Chuan reservoir is the source of domestic water and the source of ecological water for the south. The wolf cat reservoir is used as the source of water for the eastern region, the ecological water source for the eastern urban area and the water source for industrial water storage.

optimize the ecological environment of water system
improve the ecological level of the water system to highlight the characteristics of the spring city to maintain the spring water normal spray
to create "one city, two district, three corridor, four belt, five" water ecological framework
water system ecological water network based on existing rivers, lakes, wetlands as the basis, Two kinds of natural ecosystems in the southern mountain area and the northern plain are repaired and controlled, and the ecological level of the water system is improved, the characteristics of the spring city are highlighted, and the normal sprays of the spring water are maintained. The layout of the plan is "one city, two districts, three corridors, four belts and five pieces". Using spring water and river and lake connectivity project, it provides plenty of year-round landscape water for three river channels in one city.
a city - the main city area: the main city area is to plan the protection and control range of the spring water outcropping area, focusing on the four big springs, and maintain the spring pool, spring eye, spring group and the surrounding cultural landscape. A closure dam is built in the key groundwater seepage area of the spring area to recharge groundwater. Set up the early-warning line for the dynamic management of groundwater level, and implement the yellow, orange and red early warning line management. In the southern mountainous area, the water in the urban river is adjusted to the urban river, and the water of the Yellow River water and the Yangtze River water are used to fill the water of the Xiaoqing River, so as to meet the demand of the urban river landscape. The construction of river courses in urban areas will increase the utilization of spring water and reclaimed water and raise the utilization rate of water.
two areas - southern mountainous area and Northern Plain Area: the focus of water ecological restoration in the southern mountain area is the comprehensive control of soil and water conservation, and the comprehensive use of biological and engineering measures to strengthen tree planting, small watershed management, water storage, water conservation, water conservation, regulation of runoff, reduction of soil and water loss, and the promotion of ecological natural repair. To enhance the carrying capacity of environmental resources, protect the surface water sources and carry out ecological restoration of rivers in the area. The northern plain area mainly takes the backbone rivers of the Yellow River, the Apostle River, the Dehui New River and other backbone rivers and its tributary channels as the axis, planting trees, preventing wind and sand prevention, reconstructing the waterlogging and depressions, and improving the ecological features of the region.
three corridors - the ecological corridor of the Xiaoqing River, the Yellow River and the Hun River: combining the dredging and digging of the river, the comprehensive harnessing is carried out, and the landscape ecological corridor is built. The Xiaoqing River is the key river of the urban ecosystem and the waterfront landscape, plays the role of the hub of the internal and external relations in the ecology, plays the role of expressing the development culture and development of Ji'nan in the landscape, and the Ji'nan Baili the Yellow River scenic area is a National Water Conservancy Scenic Area, through the construction of ecological protection forest, the ecological riverbank vegetation is strengthened slowly. In the northern plain of Ji'nan, the river is the main flood control and drainage main road in the northern plain area. Through the construction of ecological protection forest along the river, the inflow of industrial sewage and domestic sewage in urban and rural areas is controlled, and the pollution control of point source and surface source is strengthened, so as to achieve the goal of ensuring the ecological safety of water quality and water system.
four belts - North Shahe, Yufu River, Juye River and embroidery River: the Shahe of Peking University is the ecological isolation zone of Changqing and western city, the Yufu river is the ecological isolation zone of the main city and the western city, the ecological protective belt of the Juye river is the ecological barrier in the east of the city, and the embroidery river is the north and south of Zhangqiu. The above four river control areas are also the main supply areas and surface water sources in Ji'nan spring area. The planning combined with the flood control management of the river channel, the construction of landscape forest, the restoration of waterfront vegetation, the ecological revetment and so on, and the ecological restoration.
Five: Baiyun Lake, Huashan lake, magpie mountain Longhu, Jixi wetland and rose Lake five big lake wetland ecological protection zones. Through ecological water supplement, biological water quality purification, ecological natural restoration and other measures, the function of wetland is gradually restored, the reasonable ecological water quantity is maintained, the enterprises are strictly controlled to discharge sewage into the lake, and the water quality is ensured, and the ecological environment and biodiversity of the wetland are maintained.
