      [ Chemical Machinery Equipment Network Industry News ] With the efforts of many parties, China's ecological environment has improved significantly, and construction has been fruitful: during the "13th Five-Year Plan" period, 545 million mu of afforestation was completed nationwide, 54.
    38 million mu of farmland was returned to forest, and the forest coverage rate increased to 23.
    04% , the grassland comprehensive vegetation coverage increased to 56.
    1%, and 150 million mu of desertified land was controlled

    .
    By 2021, the forest land, grassland, wetland, river water surface, lake water surface and other land types with strong ecological functions in China have increased by a total of 260 million mu

    .
    The legal framework system of ecological environment laws and regulations, standard system construction, and ecological environment damage compensation system has basically been formed, and various fields of ecological environment protection have basically achieved laws to abide

      However, behind the vigorous development of ecological construction, we must also see the degree of coordination between economic and social development and ecological and social development
    .
    This problem is particularly prominent in the development of marine economy and the construction of marine ecological environment

    .

     

      Recently, a sperm whale was rescued after being stranded in Ningbo, Zhejiang, which once again raised people's attention to the marine ecological environment
    .
    It is understood that a sperm whale ran aground in the waters near Shipu Town, Xiangshan County, Ningbo City, Zhejiang Province.
    After more than 20 hours of rescue, the rescue ship dragged the sperm whale to the destination sea area and released it to the sea

    .

     

      However, due to the urgency of the rescue time and the particularity of the tidal flat environment, rescuers have not yet "physically examined" the stranded sperm whale, so the cause of the stranding is not yet clear
    .
    The follow-up status of the sperm whales returning to the waters requires further observation

    .

     

      Studies have shown that there are many reasons for whale stranding, including climate change, changes in the ocean environment, changes in the sun's magnetic field and other natural factors
    .
    In addition,
    human marine economic activities, marine debris, toxic emissions, water noise pollution and other factors have also become one of the key reasons affecting the normal activities of marine organisms

    .

      Cetaceans are divided into two categories: pelagic and nearshore, and rely mainly on echolocation systems for navigation and detection
    .
    The stranded sperm whales belong to pelagic cetaceans, while finless porpoises and baiji dolphins belong to inshore cetaceans

    .

     

      Most of the strandings of individual pelagic cetaceans are caused by disease
    .
    Disease can cause whales to leave their ranks and follow the ocean to near shores, tidal flats or around islands

    .
    For group stranding, the more consideration is that the echolocation system of the group leader whale is affected

    .
    When the echolocation system of cetaceans is disordered or damaged, cetaceans will make misjudgments when swimming, cannot navigate smoothly, and cause them to become stranded due to wrong routes

    .

     

      In addition to the above-mentioned extreme weather that may affect the echolocation system of lead whales, man-made sonar or long-term shipping noise may be an important cause of cetacean hearing damage
    .

     

      In fact, in addition to this stranded sperm whale, there have been many whale strandings in the coastal areas of Zhejiang last year
    .
    Four strandings occurred in July 2021: 12 melon-headed whales were stranded in the waters of Toumen Port, Linhai, Zhejiang, and 5 died; 2 rough-toothed dolphins were stranded in Ningtan, Zhejiang, and were finally rescued and released; A head whale stranded off the east coast of Taizhou, Zhejiang, and one died; a Bryde's whale stranded and died off the coast of Ruian, Zhejiang

    .

     

      However, in the economic activities of fishing grounds and ports, it is less likely to create a pollution-free marine environment
    .
    Along the coast of Zhejiang, there is Ningbo Zhoushan Port, the world's largest cargo throughput port.
    Active ship traffic continuously injects a large amount of chronic water noise into the sea water, threatening the living environment of marine life

    .

     

      Water noise pollution cannot become a vacuum zone for ecological environment governance
    .
    Therefore, while the ecological environment governance is running all the way, it is still necessary to pay attention to the seriousness of the marine ecology, clarify the relevant departments and clarify the supervision responsibilities, and increase the governance of the marine ecological environment
    .
    At the same time, improve the public's risk of water noise pollution and protect marine biodiversity
