[Media Focus] Interview with China News Network Zhao Liang, Vice President of the School of Ocean and Environment of the University of Scien
On June 8, China News Network interviewed Zhao Liang, deputy dean of the School of Oceanography and Environment at Tianjin University of Science and Technology, on his views on protecting the sustainable development of marine ecosystems. The theme of this year's "Ocean Day" is "Protecting Marine Ecosystems Harmonious Coexistence between Man and Nature". Strengthening scientific publicity and social participation to fully understand the importance of marine domain knowledge to protect marine ecosystems. Talking about marine ecosystems, Zhao Liang, deputy dean of the School of Oceanography and Environment at Tianjin University of Science and Technology, said that in order to cope with the impact of climate change on marine biodiversity, research efforts on the impact of climate change on marine ecosystem structure and function should be increased, especially for typical ecosystems (estuaries-offshore-oceans). Adhere to long-term surveys and monitoring of important marine organisms, and scientifically build marine protected areas to improve protection effectiveness.

Technology and development go hand in hand, China protects marine ecology for sustainable development

China News Service, Tianjin, June 8. Title: Science and Technology and Development: China Protects Marine Ecology for Sustainable Development
Author, Shi Yunyu, Wang Zaiyu
June 8 is the 14th "World Ocean Day" and the 15th "National Ocean Publicity Day". With the continuous increase of popular science activities, the protection of marine life has gradually attracted the attention of the society. Take Tianjin Haichang Polar Marine Park as an example. "Over the past decade or so, we have actively participated in assisting government departments in the rescue and return of wild animals and endangered species. We have rescued more than 10 species, including seals and corals, and nearly 3,000 creatures, including 17 green sea turtles and two finless porpoises," said Zhang Junxin of the Biological Conservation Department of Tianjin Haichang Polar Marine Park.
The theme of this year's "Ocean Day" is "Protecting Marine Ecosystems Harmonious Coexistence between Man and Nature". Strengthening scientific publicity and social participation to fully recognize the importance of marine domain knowledge to protect marine ecosystems.
"Under the guidance of the Ministry of Rural Agriculture and other relevant authorities, the association has organized the 12th National Aquatic Wildlife Conservation Science Publicity Month since 2010, and established specific protection publicity days for species such as Chinese white dolphins, spotted seals and corals," Li Yanliang, chairperson of the aquatic wildlife protection branch of the China Wildlife Conservation Association, said in an interview. "Through thousands of science lectures and publicity activities on campuses, communities, fishing villages and fishing boats, fishermen and other marine-related practitioners can learn more about marine species, so that students on campus are willing to aspire to study marine life, so as to better protect the diversity of marine life."
In terms of using scientific and technological means to protect marine ecological diversity, Tianjin is the first city in China to carry out technological innovation and scene application of seawater desalination. Based on marine renewable energy, combined with the seawater desalination industry, it can not only alleviate the problem of water difficulty, but also reduce energy consumption and protect the ecological environment. At present, Tianjin is the only region in China where all three mainstream technologies of seawater desalination have been applied, applying for nearly 200 relevant patents, and many technologies have entered the international advanced ranks.
When it comes to marine ecosystems, Zhao Liang, deputy dean of the School of Oceanography and Environment at Tianjin University of Science and Technology, said that in order to address the impact of climate change on marine biodiversity, research efforts on the impact of climate change on marine ecosystem structure and function should be increased, especially for typical ecosystems (estuaries - offshore - oceans). Important marine organisms adhere to long-term surveys and monitoring, and scientifically build marine protected areas to improve protection effectiveness.
On this basis, various departments in Tianjin have also carried out various related work. It is understood that Tianjin plans to release fish, shrimp, crab, shellfish and other seedlings 1 billion units in the coastal waters and important inland fishery waters this year, and release 20 varieties to remove suspended particulate matter in the water body, so as to increase the primary productivity of the water ecosystem. It is estimated that the annual proliferation of shellfish in Tianjin's waters can reduce about 3,400 tons of carbon, 800 tons of nitrogen and 160 tons of phosphorus, which can effectively promote the carbon sink of marine fisheries and purify water quality.
In order to protect marine wildlife more scientifically, China has established various marine life conservation alliances such as the Chinese sturgeon, Yangtze finless porpoise, and sea turtles. Since the establishment of the China Sea Turtle Conservation Alliance in 2018, it has assisted the fishery authority to release and rescue more than 600 sea turtles. At the same time, China has established a number of national nature reserves according to the characteristics of marine life. Taking China's first sea turtle rewilding base - Guangdong Huidong Sea Turtle National Nature Reserve as an example, while providing sea turtles with spawning and migrating breeding grounds, it also regards "rescue, convalescence, rewilding, and release into the sea" as important functions of the protected area, which protects the marine ecosystem to a certain extent.
"For a long time, many departments in China have carried out a series of marine habitat protection work. In addition to daily monitoring, investigation, and personnel training in nature reserves, there are also work such as banning illegal fishing, carrying out a ten-year fishing ban on the Yangtze River, and building marine pastures. These are all related to the protection of the marine environment and aquatic biodiversity." Li Yanliang said. (End)
