Rivers and lakes are the blood of the earth. In recent years, the Ministry of Water Resources has organized and implemented the Mother River Recovery Action to speed up the restoration of the ecological environment of rivers and lakes, so that rivers can regain their life and rivers can regain their vitality. Next we focus on Xiaoqinghe. The Xiaoqing River located in Shandong Province originated from the Jinan Spring Group and has a history of nearly 900 years. It is currently 229 kilometers long and has a drainage area of 10,433 square kilometers. It is an important flood control channel in Shandong. Among them, the Jinan section is the only sewage discharge and flood discharge river within the urban area. In the past few years, due to serious pollution, it became a worse than Class V water body. Today, Xiaoqing River has become a new landmark in Jinan. How is this achieved?
html On the Xiaoqing River in April, the willow trees along the bank spit out new green, and various flowers bloom one after another. Playing shuttlecock, walking, and rehearsing cultural programs, when the reporter came to Wuliu Island along the Xiaoqing River early in the morning, many citizens had gathered here for morning exercises.
Speaking of the changes in Xiaoqinghe over the years, Jinan citizen Cui Hongjun has a deep understanding. He lives near Xiaoqing River. As a photography enthusiast, he has been photographing Xiaoqing River for more than 20 years. He told reporters that in the 1970s and 1980s, with the acceleration of industrialization and urbanization, some companies discharged sewage into the Xiaoqing River without any treatment. Coupled with the discharge of various domestic sewage and garbage, the beautiful Xiaoqing River It became a "little black river" and many people even moved because of it.
Jinan citizen Cui Hongjun: is such a big river clam. When I was young, my teenagers would go to the small river to touch the river clam. Later, as soon as the pollution disappeared, I felt that this was very unpleasant. I thought how could such a nice river turn into a smelly river. I have also reported it to the relevant departments, and I look forward to when it can be controlled!
In 2017, Jinan began to make great efforts to carry out comprehensive improvement of the ecological environment of Xiaoqing River. A total of more than 60 enterprises along the river have been shut down and relocated, and thousands of illegal enterprises have been banned. "Scattered pollution" enterprises not only cut off external pollution sources, but also cleaned up silt pollutants in rivers and invested more than 10 billion yuan to repair the shortcomings of sewage pipe networks and other facilities.
Xu Xiaochi, senior engineer of the Drainage Management Office of Jinan Urban and Rural Water Affairs Bureau: The number of new and expanded sewage treatment plants has reached 11, which can effectively collect and treat sewage to ensure that insufficient sewage treatment capacity causes sewage overflows and affects the water quality of rivers. , affecting the water quality of Xiaoqing River.
Through the continuous joint efforts of ecological water replenishment and ecological restoration, the water quality of Xiaoqing River has been significantly improved. Currently, more than 200 aquatic organisms, including the Chinese giant catfish, have been monitored. The water quality has improved, and the local area has created an ecological landscape belt along the Xiaoqing River. The ecological environment has been greatly improved, and the neighbors Cui Hongjun moved away have all moved back to the banks of the Xiaoqing River.
Jinan Citizen Liu Tao: has almost come back now, because after all, we started playing it since we were young, and then our conditions were improved, and then the water became better again, so everyone is willing to come back.
Today, along the Xiaoqing River, industries such as education, residence, and commerce are vying to move in, gradually forming a characteristic economic development belt and becoming a new landmark in Jinan.
Zhou Weifang, director of the Xiaoqinghe Service Office of the Jinan Water Conservancy Engineering Service Center: This part of is mainly urban home shopping malls. In addition, some of this part are enterprises, including tea towns selling tea and other businesses. With the improvement of the entire landscape, our Xiaoqinghe has created 6 landscape zones, which are part of cultural tourism and part of the cultural tourism industry.
In Shandong, this year, the local government plans to build the Xiaoqing River Ecological Corridor. The 229-kilometer Xiaoqing River will be built into a multi-functional ecological corridor integrating water system wetlands, leisure and recreation, water and land transportation, cultural inheritance and other elements, ensuring Water security, protection of water ecology, development of water economy, and improvement of water people's livelihood.
Flood Control Safety Network Xiaoqing River has become a demonstration of river management
Xiaoqing River is the main artery of flood control and drainage in central Shandong. Since most of its 48 tributaries are flash flood-type rivers, it is easy to cause the water level of the main stream to rise rapidly after joining. In 2019, the passage of Typhoon "Lekima" severely affected the entire Xiaoqing River basin, causing economic losses of more than 10 billion yuan. What is the ability of Xiaoqing River to prevent floods today?
Cuijia Village in Huantai County is located along the Xiaoqing River.Wang Keqi, secretary of the village party branch, told reporters that he is still scared when he thinks back to the floods caused by the typhoon in 2019.
Wang Keqi told reporters that most of the more than 400 people transferred at that time were elderly people. Gongs, drums, alarms, and loudspeakers are necessary equipment organized by the village committee every year to remind villagers to escape.
Not only are the lives of villagers threatened, but the floods that occur almost every year in June and July also cause a large area of corn production to decrease.
In order to ensure flood control safety, after the floods in the entire Xiaoqing River basin in 2019, Shandong Province listed the comprehensive flood control management of Xiaoqing River as the province’s number one water conservancy project, investing 18.2 billion yuan to ensure timely flood control by widening the river channel, building sluices, etc. Drainage and drought can store water.
Wang Keqi, Secretary of the Party Branch and Director of the Village Committee of Cuijia Village, Huantai County: During Typhoon Lekima in 2019, the river with a flow of 500 meters was completely flooded. The year before last, the flow rate was more than 700, and there was no problem at all. The water was not big.
In order to reduce the pressure of flood control, the water conservancy department also built an 83.3-kilometer flood diversion channel on the Xiaoqing River.
Zhang Bin, deputy director of the Zibo City River and Lake Long System Support Service Center: The water level of the Xiaoqing River, and the excess water from the upstream, enters the floodway from the flood diversion mouth, which can solve the waterlogging problem in Zibo City, especially in the Huantai area.
At the same time, the Xiaoqinghe digital twin system is also accelerating the construction to provide accurate data information in response to extreme weather.
Li Zhanhua, Director of the Planning Department of the Haihe Huaihe Xiaoqing River Basin Water Conservancy Management Service Center in Shandong Province: can predict its disaster situation in advance, greatly improving the accuracy of river flood peak prediction and dispatching level.
After treatment, the Xiaoqing River, which used to be frequently flooded, has now been built with a flood prevention safety net and has become a demonstration project for river management.
Without the threat of floods, not only the villagers of Cuijia Village can farm with peace of mind, but also foreign investment has been invested in the development of the village. Relying on the rich water system, Cuijia Village attracted more than 200 million yuan at a time, built a Qianmo town integrating leisure, freshwater aquaculture, and hot spring development, and developed a cultural tourism industry.
Wang Keqi told reporters that when the cultural tourism town is fully built, it will solve the employment problem of many people in the village.
Revitalizing the Water Economy The 900-year-old ancient river has regained its vitality
Xiaoqing River in Shandong was once cut off due to insufficient water and other reasons. Today, Operation Mother River Revival has fully restored navigation on the Xiaoqing River, which had been suspended for 27 years.
CCTV reporter Shao Haicheng: I am now at Gaoqing Port in the Zibo section of the Xiaoqing River in Shandong. Look in the direction of my finger. A container ship departing from Wuzhou Port in Guangxi and loaded with more than 2,000 tons of ore is about to dock. This is the first heavy-load passage of the Haihe River intermodal transport after the comprehensive management of Xiaoqing River and the resumption of navigation.
reporters learned on the spot that these more than 2,000 tons of ore are the raw materials needed by a large papermaking company in Zibo, Shandong. In the past, this batch of ore had to be transported from Weifang Port to the factory, which was a long distance and long transportation time. Now, this batch of ore can pass through Xiaoqing River and directly reach Gaoqing Port.
Kang Peng, logistics manager of a company in Shandong: Before , the distance from Weifang Port to the factory was 170 kilometers. After the opening of Gaoqing Port, the distance to the factory is 7 kilometers, which saves transportation time for enterprises.
The Xiaoqing River Channel runs through the five cities of Jinan, Binzhou, Zibo, Dongying and Weifang. There are hundreds of large-scale steel, paper, chemical and ceramics companies along the route, which require a large amount of raw materials. Transportation through Xiaoqing River will reduce a lot of costs.
Yang Zunwei, deputy director of the Water Transport Institute of Shandong Provincial Transportation Design Group: Preliminary estimates indicate that the transportation needs of the existing enterprises along the Xiaoqing River are about 40 million tons per year. If everything is transported by water, the economic value saved would definitely be in the billions.
In order to further promote the cost reduction and efficiency improvement of Xiaoqing River shipping, relevant departments in Shandong have also formulated policies for the Xiaoqing River market cultivation period, including free lock crossings, shipbuilding incentives and subsidies, etc., to effectively promote the initial development of Xiaoqing River shipping.
At Xiaoqinghe Zhangqiu Port, a ship carrying wind turbine accessories is leaving the port and heading to South Korea. This is the first domestic and foreign trade integrated transportation business carried out since the port operation along the Xiaoqing River.
Yang Zunwei, deputy director of the Water Transport Institute of Shandong Provincial Transportation Design Group: If a heavy item is transported by road, it first needs approval from the highway department. Secondly, if its size is too large, it will not be able to pass some bridges, so it is difficult to install After boarding the ship, there are basically no approval procedures required along the way, so transporting large items by water should be a very advantageous method of transportation.
At present, Shandong has begun to study the connection project between the Beijing-Hangzhou Grand Canal and the Xiaoqing River. In the future, the Xiaoqing River will be connected to the river and the sea. The magnificent transformation of the ancient river channel has opened up a new land-sea channel for Shandong, and also added a new "golden waterway" for inland shipping across the country.
