尊敬的各位专家、学者:长江口地处我国经济社会高度发达的东部沿海,与世界其它河口发达地区一样,长江口及邻近海域的生态与环境面临巨大压力和挑战。同时,大河输入、黑潮和东亚季风的相互作用,构成了长江口及邻近海域独特的区域海洋学环境,是地球上研究自然变化和人类活动对近海环境演变和海洋生态系统响应的“天然实验室”。 Dear experts and scholars, The Yangtze Estuary is located in the economically and socially developed eastern coast of China. Like other developed estuaries in the world, the ecology and environment in the Yangtze Estuary and its adjacent areas are under tremendous pressure and challenges. At the same time, the interaction between the major rivers and the Kuroshio and the East Asian monsoon constitutes a unique regional oceanographic environment at the mouth of the Yangtze River and its adjacent waters. It is also a natural natural and human-induced response to the changes in the marine environment and marine ecosystems. laboratory".
