On August 29, the Liaoning Provincial Department of Natural Resources released Liaoning’s first marine ecological early warning monitoring bulletin – “2023 Liaoning Provincial Marine Ecological Early Warning Monitoring Bulletin” (hereinafter referred to as the “Bulletin”).
The communiqué implements the requirements of the “Marine Environmental Protection Law of the People’s Republic of China” and, based on the marine ecological early warning monitoring data of Liaoning Province, comprehensively presents the marine ecological pattern and status of Liaoning Province through systematic analysis and scientific evaluation. It explains the status and changing trends of typical coastal ecosystems such as estuaries, bays, salt marshes, seagrass beds, seaweed fields, muddy coasts and sandy coasts, as well as the occurrence of marine ecological disasters such as red tides, floating large algae and jellyfish, and summarizes the work of marine ecological protection and restoration.
The results of the communiqué show that the seawater conditions in the coastal waters of Liaoning Province are good in 2023, and indicators such as temperature, salinity, pH, and dissolved oxygen are all within the normal range. The bottom of Liaodong Bay and the coastal areas east of Dalian (Yellow Sea) are eutrophic. The community structure of phytoplankton, zooplankton and large benthic animals is basically stable. Liaoning Province has a vast area of coastal wetlands and rich bird resources. Typical ecosystems such as the Liaohe Estuary, the Yalu River Estuary, and the Xingcheng Seagrass Bed are generally stable. Ecological problems such as red tides, large floating seaweed aggregations, and local biological outbreaks of moon jellyfish still exist. Marine ecological protection and restoration projects continue to advance, and good results have been achieved in the construction of ecological civilization.
