The Provincial Department of Natural Resources has released the province’s first marine ecological early warning monitoring bulletin, titled “2023 Liaoning Province Marine Ecological Early Warning Monitoring Bulletin.” This bulletin implements the requirements of the “Marine Environmental Protection Law of the People’s Republic of China” and presents a comprehensive analysis of the province’s marine ecological pattern and status.

The bulletin provides a systematic analysis and scientific evaluation of the province’s marine ecological data, covering typical coastal ecosystems such as estuaries, bays, salt marshes, seagrass beds, seaweed fields, muddy coasts, and sandy coasts. It also discusses the occurrence of marine ecological disasters like red tides, floating large algae, and jellyfish, and summarizes the work of marine ecological protection and restoration.

According to the bulletin, the seawater conditions in the coastal waters of Liaoning Province were good in 2023, with indicators such as temperature, salinity, pH, and dissolved oxygen within the normal range. However, the bottom of Liaodong Bay and the eastern coastal areas of Dalian (Yellow Sea) were found to be eutrophic. The community structure of phytoplankton, zooplankton, and large benthic animals was generally stable, and the province’s coastal wetlands and bird resources were found to be rich and diverse.

Typical ecosystems such as the Liaohe Estuary, the Yalu River Estuary, and the Xingcheng Seagrass Bed were generally stable, but ecological problems like red tides, large floating seaweed aggregations, and local biological outbreaks of moon jellyfish still exist. Despite these challenges, the province’s marine ecological protection and restoration projects continue to advance, with good results achieved in the construction of ecological civilization.
