The coastal zone is a complex natural system consisting of a marine and a terrestrial environment. It is used excessively by a variety of coastal users because of its important resources. This study attempts to analyze the utilization characteristics of the coastal zone to formulate a structural model for the coastal zone management. The results show that the utilizations can be classified into three key categories, namely, industrial and nonindustrial use, by local residents and non-local residents, in limited numbers and large anonymous groups. These user groups conflict with each other. In order to describe the relationships between utilization, environmental protection and management, the author proposes a triangular pyramidal model consisting of three apexes representing, industrial use, non-industrial use, and environmental protection with a pinnacle representing the management. An effective coastal zone management will strive to keep the balance between these three apexes. Based on this model, the need for a dual structure management, large and small area management of the coastal zone is inferred
