Abstract:Exploring marine resources is one of the key issues of the marine economy. It developed very fast in the last several decades in China, most of the marine resources exploring are carried out in the coastal area, especially for the marine biological resources. Accompanying the marine resources exploring activities, the marine environment has a great change, such as the marine pollution, harmful algae bloom, and green algae bloom etc.. How to balance the conflict between the marine resources exploring and the marine environmental protection is a big challenge for the research and management. To avoid the near nearshore pollutions, establishing ecosystem based coastal management system will be one of our main tasks in the near future, to meet the need for the marine resources, we have to go the deep blue.
