China News Service, Fuzhou, March 29 (Zheng Jiangluo) In the waters of Nanwan Village, Yantian Township, Xiapu County, Ningde City, Fujian Province, the Chinese White Dolphin, a national first-class protected wild animal, frequently appeared, playing and tumbling near the sea. Did not leave until low tide.
Liu Weishun, a photographer in Xiapu County who has been chasing Chinese white dolphins, said in a recent interview with a reporter from China News Agency that dolphins are very sensitive to marine water quality and are regarded as living indicators to measure the marine ecological environment; their appearance highlights the local marine ecology. The environment has been significantly improved.
Located in Ningde City in the eastern coastal area of Fujian, the marine aquaculture industry was extensive and disordered before, which had a negative impact on the marine ecological environment.
Since 2018, the city has carried out comprehensive rectification of the marine aquaculture industry. The densely-populated breeding cages and white foam floats on the sea no longer exist.
In recent years, Fujian has guarded Bihaiyintan and embarked on a road of comprehensive treatment of sea-floating garbage with distinctive characteristics.
Not only in the seas of East Fujian, but also in the seas of Xiamen, the scene of dolphins chasing the waves is also reproduced, and rare marine creatures such as Chinese horseshoe crab are recuperating here.
According to the Fujian Provincial Department of Ecology and Environment, in 2020, a total of 273,000 tons of marine debris were cleaned up in Fujian. In the fourth quarter, the distribution density of marine debris on key shores in the province decreased by 36% compared with the same period of the previous year.
In order to protect Bihaiyintan, Fujian has strengthened smart governance and built a scientific and technological support and guarantee mechanism.
Liu Chen, the fourth-level investigator of the Ocean Division of the Fujian Provincial Department of Ecology and Environment, said that in view of the wide range of marine debris, the traditional treatment methods are expensive and often get twice the result, relying on modern technology and information methods such as ecological cloud platforms to promote "Managed" has changed from "Managed" and "Good".
Fujian’s 13 key bays, 235 coastal waters monitoring sites, 11 major rivers entering the sea, and 25 major watersheds entering the sea have been included in the management of the ecological cloud platform, and drones and shore-based cameras are regularly scheduled to monitor floating garbage and marine debris in key areas. The land-source pollutants entering the sea are monitored, and the aerial images, monitoring data and other information are all integrated into the "Marine Information Map".
"This year we also plan to set up high-definition cameras on key shores, and we will further increase monitoring sites in the future." Liu Chen said that the data will be connected to the ecological cloud platform in real time. Through identification and statistical analysis, the results will be sent to coastal areas and local management personnel in real time. You can also see the results in real time through the ecological cloud platform to "solve the problems of insufficient timeliness and delay in cleaning up in the past."
Xiamen City takes the lead in developing a marine garbage monitoring and early warning system to predict and forecast the drift trajectory of the Jiulong River's garbage entering the sea; Fuzhou has built the country's first marine garbage video monitoring network system to achieve panoramic monitoring of the sea area of key coastal sections...Fujian also Enabling intelligent analysis and early warning, using artificial intelligence recognition algorithms, based on basic data such as water depth, shoreline, and terrain, to monitor, identify, early warning and analyze floating objects, and to study the distribution area and diffusion trajectory of marine debris.
"Through the ecological cloud platform, all localities can grasp the location, main types of garbage, garbage coverage area and density of the prominent shore section of the sea-floating garbage problem in their jurisdiction in real time, upload pictures and video materials after treatment at any time, and realize the prevention and control of cloud-based "One-Net" scheduling. ." Liu Chen said.
With "shore management, river basin barriers, and clear seas", Fujian makes the beautiful bay more "clean water, clean beaches, gathering fish and gulls, and harmony in the sea of people".
Liu Chen said that the treatment of marine waste is a comprehensive treatment. “We actively promote the entire chain of governance, use the ecological cloud platform, provide smart services, intelligent management and control, ensure precise governance, save governance costs, and improve governance efficiency”.
