Theoretical Study On Man-sea Relation And Regional System Of Man-sea Relation

Nowadays theoretical and practical studies on Man-Land system, both at home and abroad, have already come onto an advanced stage. Over the last few decades, with the development of the whole ocean undertaking studies on human geography of sea are presently on their way to advanced level. In this context, this dissertation attempts to do some research on the man-sea system, which is assumed to be intersection of the two fields mentioned above.At the very beginning, the reason why this subject was chosen is given and the aims and implications of this study are clarified. It is our hope that this study could accomplish two jobs. One is to make the man-sea system more conspicuous in the field of man-land relation. The other is to draw more attention of the academia to the study of man-sea system's nature, mechanism behind its evolution and etc.The whole dissertation is divided into six chapters. In chapter one there is a review on man-land system studies both at home and abroad, which mainly focuses on man-land theories, methodology, the co-ordination of man-land relation, regional system of man-land relation and practical studies. Then studies on marine economy geography, marine geography of politics, marine culture, integrated management of coastal zone and ocean ecology and environment are reviewed.In chapter two, the concept of man-sea relation and regional system of man-sea relation is officially put forward. And some basic ideas related such as the meaning of man-sea relation, spatial coverage of this kind of study, the content of the study, the nature of the regional system of man-sea relation, some principals of the analysis of the regional system are expounded and explained.In chapter three, from the perspective of system and component, we study the components of the man-sea system and the components flows, based on which the components'effect on the regional system of man-sea relation is analyzed. This amounts to the analysis of the system's mechanism. In chapter four, the spatial and temporal evolution of the regional system man-sea relation in China's coastal areas. The whole process of evolution is divided into three phases, namely primitive era, agricultural era and contemporary era. The evolution of the man-sea interaction is mostly demonstrated by human society's exploitation of ocean resources. Based on the study of chapter three and some complex science theories, we examine the mechanism.Chapter five examines the spatial structure of the regional system of man-sea relation and it's regional types. The mechanism of the formation of spatial structure is analyzed. Currently the spatial structure in China is three major marine economic regions coexist, namely Bohai Sea rim, Yangtzi River delta and Zhujiang River delta. In the end, we analyze the different regional types in terms of the characteristics of components flows.The coordination of the man-sea relation is studied in chapter six mainly in terms of methodology. After a brief explanation of the meaning and nature of coordination of man-sea relation, we shift focus to the measurement of the extent of coordination. There are already some most general methods, and some aiming at solving the coordination problem between economy and resources or economy and environment. Another method is assessment of the carrying capacity of ocean areas. It is actually a way to decide whether the subsystems of the man-sea system are developing in coordination. And the conclusion.
