Abstract

Coastal wetlands have high community diversity and species abundance, serve as important habitats for fishes to spawn, feed and overwinter and for birds to feed, perch and breed, which has identified coastal wetlands as being the most valuable ecosystem type in terms of ecosystem services. However, coastal wetlands have become ecologically fragile ecosystems because of increasing human activities, leading them one of the most sensitive areas to climate change. By focusing on national strategic technology plans for environmental protection and ecological construction of coastal wetlands in China, The Yellow River Delta Ecology Research Station of Coastal Wetland of Chinese Academy of Sciences (YRDS) has carried out many research projects on the environmental protection and restoration of coastal wetlands in the context of land-sea interaction processes and sustainable development. YRDS quantified the current status, dynamics and driving mechanisms of carbon sink in coastal wetlands, and clarified the impacts of hydrological processes and soil water-salt migration on carbon cycle processes of coastal wetlands by field long-term monitoring and manipulation experiments. YRDS revealed the response and adaptation mechanisms of ecosystem structure and functioning of coastal wetlands to climate change and human activities, and is leading the research on the response of coastal wetlands to climate change. YRDS constructed a technical system and developed key technologies for ecological restoration of degraded coastal wetlands, proposed a theoretical and technical model of "healthy coastal wetlands" to achieve a coordinated development of protection and utilization, which have promoted the advancement of coastal wetland ecology research with regional characteristics. These researches have not only filled gaps in long-term observation and research of coastal wetlands in China, especially in the northern estuary delta, by providing fundamental data, scientific basis and key technologies for the ecological protection and restoration of coastal wetlands in the Yellow River Delta, but also provided an important supporting platform for improving the theoretical research and regional sustainable development in the field of coastal wetlands.
