Abstract:With the constant rise of the productivity, the ability to understand and impact nature is consequently increased, which leads to the expansion and deepening of the man-land interaction. At the early stage of the development of man-land relationship, the interaction between man and land was more intensive than that between man and sea.
This paper firstly expounds the theory of sea-land compound ecosystem.The sea-land compound ecosystem is an ecosystem which integrates society,economy and nature,SENCE in short.Natural environment is the basis of SENCE, the flow of substance, its life line, and the regime of society, its web of vein.
Only by combining the sea and the land, can the whole sea-land ecosystem and the separate ones as well function the best. It is inevitable that the sea shifts from the stage of being a socially isolated ecosystem to a stage of being integrated by land ecosystem. Each open system, no matter what size, must interact with environment in the aspects of substance, energy and information. As for individual systems, sea and land ecosystems must have been interacted with each other in every way. It leads to the interaction between man and the sea. The exploration and exploitation of the sea by mankind is part of the global ecological process, and it is consistent with the laws of evolution of the society and the nature as well. The component of mankind is the most active factor in the whole man-land system. Human activities exert influence on every area of the sea-land compound ecosystem, which is part of the man-land system. It is safe to say that the demand of man for food, water and other necessity or even luxury product is one of the driving forces for the development of the present sea-land ecosystem. While the resources on the land are getting scarce, the sea is inevitably included in the chain of supply by mankind. Being aware of the relationship between mankind and the sea, and, we must keep the lessons from the past in mind that man must live in harmony with sea. We must pursue the purpose of sustainable development while exploiting the marine resources.
