Xiamen Harbour, one of the major deepwater harbours in China, lies in the west coast of Taiwan Strait. Xiamen Island and its surrounding offshore islands exhibit diverse habitats for numerous marine species including the endangered Chinese white dolphin and amphioxus. However, over the past half century, Xiamen has been developing and drastically transforming itself from a fishing village into an international port city, attracting millions of visitors from home and abroad every year. Along with this economic transformation was the great human alteration of the coastline in Xiamen. Thus the coastal marine environments and marine biodiversity are suffering from mass threats, including the need for more land. Under the pressure of land reclamation and nutrients/pollutants input from the Jiulong River, Xiamen is facing a great deal of serious environmental problems, including eutrophication, HAB, and habitat loss. And yet, methods to evaluate the ecological impacts of artificial land coastal structures and provide useful information for the government and stakeholders are still a big challenge for Chinese researchers.
Yunwei Dong is a professor of State Key Laboratory of Marine Environmental Science (Xiamen University) and College of Ocean and Earth Sciences of Xiamen University. Yunwei obtained his Ph.D. in Ecology from Beijing Normal University in 2002. From 2002 to 2010, he worked in Ocean University of China, and in 2006-2007, he worked in Stanford University as a visiting scholar. During 2016-2017, he works in University of California, Davis as a visiting scientist in Marine ecology and evolution.
His research focuses on the ecological impacts of climate change and human activities, including land reclamation and artificial infrastructures, on the coastal ecosystems along the Chinese coastline. He is PIs of over ten National and provincial projects and has published 81 peer-reviewed articles.
My research uses in-situ observation as well as experimental and modeling approaches to study processes controlling macro-nutrient (N, P, Si) delivery and cycling from watershed to coast. Current and past projects focus on riverine nutrient transport, nutrient budgets, denitrification, and eutrophication issue in river, reservoir, estuary and bay water. I established Environmental Process Lab in 2009, which endeavors to understand how human activities and climate impact nutrient biogeochemstry and environment at various spatial and temporal scales.
I like much to collaborate with scientists with different background and do interdisciplinary researches. Future works will focus on the coupling of biogeochemical process and physical process. Specific interests are nutrient cycling and export in the river-estuary interface. I also realized the importance of knowledge transfer to decision maker and manager. We provide supports to government in nutrient management strategy, GIS based information system, modelling water quality and securing drinking water source, etc.
