Along the north along the highway to the west, in the northwest of Chongming Island, there is a 18-kilometer-long central Henghe across the entire Xinhai Town. Not only that, many village-level rivers in Xinhai Town have been effectively managed, and villagers can enjoy a relaxing time by the river for walking, fishing, and morning exercises. In recent years, Xinhai Town has vigorously promoted the construction of beautiful rivers and lakes, comprehensively improved the landscape of the river shoreline, and implemented a new operation and management mechanism featuring "enterprise + township", so that the "stinky rivers" have been transformed into "landscape rivers".
"Water" is a special concern of the people, and a good water environment is related to the quality of life. At present, there are 194 kilometers of rivers at the town and village levels, which are jointly governed by the Xinhai Town Government and Guangming Resident Enterprises. Wang Weiyan, director of the Agricultural Development Office of Xinhai Town, introduced that many years ago, Xinhai Town's "inferior five types of rivers" and "rain and sewage mixing" and other problems were prominent, in order to further improve the management and protection of rivers and lakes in the town and the rectification of problems, in 2020, Xinhai Town and Guangming resident enterprises established a "double river chief" working mechanism to draw a new picture of beautiful rivers and lakes for residents.
Source control, source control and pollution interception
"Look, that's the Haixing River!" Standing near the Yuejin area along the highway in the north, following the direction pointed by Zhou Shiyang, a member of the River Chief Office of Chongming Farm Company, the clear Haixing River and the pavilions along the coast come into view. A few years ago, Haixing River, as the main town-level river in charge of Guangming resident enterprises, was blocked by silt in the river due to problems such as the discharge of tailwater from a large number of fish ponds, and at the same time, due to the poor fluidity of the water body and the weak self-purification function, it became a black and odorous polluted place, which seriously affected the normal life of nearby residents.
"The problem of water pollution is in the water, and the root cause is on the shore, and if you want to deal with it, you must solve it from the source. Zhou Shiyang said that after docking with the district and town river chief offices, Xinhai's "Shuanghe Chief" jointly formulated a preliminary plan. In view of the pollution caused by the discharge of tailwater from fish ponds, relevant enterprises are required to implement aquaculture pollution reduction, adopt low-density aquaculture methods, reasonably arrange drainage time, and prevent the concentrated discharge of nutrient-rich tailwater. For the broken end of the river, water quality improvement measures are taken, including cleaning up the polluted sediment in the river, physically adsorbing pollutant substances in the river, and arranging inspectors to clean up the river surface and its surroundings regularly.
Of course, in addition to controlling the source and intercepting pollution on the shore, the most important thing is to restore the water body. Zhou Shiyang said that only by building a relatively stable biome can the self-purification ability of the river be truly improved. "Through the combination model of 'ecological governance', the Haixing River adopts the route dominated by the construction of submerged vegetation system, supplemented by aeration and aeration and biological treatment, and builds an 'underwater forest' at the bottom of the Haixing River to enhance the self-repair ability of the water body. At the same time, in view of the environment on both sides of the river, the "Shuanghe Chief" jointly formulated a beautification plan, replanted greening, and enhanced the landscape effect. The water quality of the Starfish River has gradually been effectively improved, and it has become a landscape river for surrounding residents to take a leisurely stroll.
The Shuanghe chief system improves the happiness of residents
The re-weaving of the water network not only makes the ecosystem in the Xinhai area more harmonious, but also enhances the sense of gain of residents. Talking about the new changes of the river, clear water and green banks, Uncle Li, who lives in Xinyuan New Village, Xinhai Town, has a lot of feelings, "In the past, the river near the community always had a black smell, and when it rained heavily, the small river was full, and the water overflowed to the road, causing potential safety hazards to vehicles and pedestrians. "The root cause of the related problems is that there is a mixed discharge of rain and sewage in old communities such as Xinyuan and New Village. Due to the particularity of community management, after the residents put forward their opinions, the river chief of the government and enterprises need to negotiate, and formulate a community road rain and sewage diversion transformation plan, "after the completion of the rain and sewage diversion reconstruction project, the original old pipeline only undertakes the task of sewage discharge, and the new rainwater pipe network is added to enhance the drainage capacity, and the rainwater is directly discharged into the town-level river, which can prevent and control water pollution from the source." Zhou Shiyang said.
When it comes to the problem of river bank management, Wang Weiyan also has a lot of feelings. "The riverbanks are often the hardest hit areas of illegal construction, and illegal construction along the river is the 'key household' of indiscriminate sewage discharge. Wang Weiyan told reporters that in September last year, the Long March 30 River, as one of the rivers for Xinhai Yuejin farmland planting and drainage, was reported by the masses that there were many illegal construction of barrages and simple iron bridges in the river. Due to the particularity of river jurisdiction, the River Chief Office of Chongming Farm Company and the Xinhai Town Government have held many river chief work meetings. "There are many difficulties in demolishing violations, and the illegal construction households are resistant to it, and they are reluctant to agree to the removal, and the Chongming Farm Company, which is responsible for daily management, does not have the right to enforce administrative law. ”
In order to persuade the villagers, the members of Xinhai "Shuanghe Chief" visited the villagers many times, and had long talks with the illegal construction households, explaining the significance of river governance through policy guidance and pros and cons statements, and finally won the understanding and support of the villagers. During the official demolition process, the river chiefs also supervised the construction to minimize unnecessary losses to the masses. "There is no illegal construction, the scenery of the river is indeed more beautiful, and now I will take a walk here if I have nothing to do. "The illegal buildings along the river were successfully demolished, and nearby residents became the biggest beneficiaries of "clear water and green banks".
In order to ensure the long-term governance of the river, in 2023, while promoting online and offline through WeChat groups, outdoor electronic screens, brochures, etc., Xinhai Town will also continue to carry out themed river protection activities such as "Shuimei Xinhai Agricultural Pollution Operation and Maintenance into the Community" and "'River' I Protect the Clear Water Together", and actively organize private river chiefs, volunteer teams of Chongming Farm Company, and "River Xiaoqing" volunteer action teams to clean up a total of 50 kilometers of rivers and clean up 12 tons of garbage, dead branches and weeds in the river.
Landscape design to enhance the shoreline project
In the past two years, while Xinhai Town has been striving to do a good job in "water control", it has also been continuously improving the ecological landscape corridor of "roads under the forest, forests at the water's edge, and waterways adjacent".
Since 2012, the Shili Henghe River treatment project began, and on the basis of measures such as cleaning up silt and building slope protection, the landscape design has been improved by 208,000 square meters. Walking along the Hongxing area of the North Along the Highway, the newly built riverside trails, river railings, and pavilion seats have greatly improved the landscape quality of the public spaces on both sides. Wang Weiyan introduced that since the establishment of the "Shuanghe Chief" working mechanism, the landscape transformation of the Shili Henghe River has also been continuously optimized, and the Xinhai Town and Guangming resident enterprises have continuously improved the ecological and cultural landscape river that displays the native tree species of Chongming and retains the nostalgic culture of Chongming. "In the landscape transformation, we deeply excavate and use Chongming's native plants, including 45 kinds of native plants in Chongming, including willows, cannas, a bunch of red, etc., which is not only Chongming's first plant-based humanistic landscape that reflects the nostalgic culture, but also an important popular science education base for primary and secondary school students to understand native plants and build a world-class ecological island. Looking at the new look of the landscape river, Wang Weiyan's face was full of pride and happiness.
Next, Xinhai Town will also cooperate with Chongming Farm Company to take the "World Water Day" and "China Water Week" as an opportunity to carry out river chief system publicity activities such as "'Tong' Protecting Blue Water and Facing the Future Together" into the campus, and enhance the town's sense of responsibility of "saving water, cherishing water, loving water, and protecting water" through water knowledge preaching, drawing environmental protection bags, etc., so as to achieve the governance goal of "smoother river, cleaner water, greener shore, and more beautiful scenery".
