Research On The Framework Of Sea Area Use Management Information System Based On Geographical Space

As an important natural resorurce, sea area is an important basis and carrier of marine economic development. Especially in the content. Of the rapid development of economy, science and techonlogy, dwindling land resources, increasing population and deteriorating enviornment in the world today, the attention paid by all countries to the coean has reached an unprecedented degree. In response to this world trend, China has exercised standardized control sea area use since 1993. Through over eight years' exploration and practice, the basic framework for the regulatory system of sea area has basically come into being, and, in 2001, the Law of the People's Republic of China on the Management of Sea Area Use with significance of a milestone was published.In order to effectively implement Article 5 of the law: "The State shall establish the information system for the management of sea area use and carry out surveillance and monitoring of the status of the sea area use." it is necessary for us to research into and establish the information system for the management of sea area use. It is in response to such needs that the paper is written.Firstly, as the geographical space characteristics and the artificial character of sea area use are the two very important factors in the management of sea area use, the paper employs such advanced technologies as object orientation and work flow management and, in combination with such technologies as the full-module GIS, remote-sensing and GPS, conducts the research on the logical structure and basic framework of sea area use management on the basis of geographical information, thus laying the foundation for the eventual establishment of the information system for the management of sea area use .Secondly, apart from the spatial character, the operational data of sea area use management are characterized by multi-source, multiple scale, and coordinate, complex type and large quantity, etc, so this paper has laid emphasis on studying the spatial datamodel and the data framework related to the management of sea area use, solved a series of key technical problems such as check and correction, organization and structrue, quality management and standard norms for the geographical sapce data associated with the management of sea area use, proposed various practical and effective ways of storing and managing spatial and non-spatial data and established the spatial data base system for the management of sea area use.Thirdly, as different sea areas have different functions and values for use, the paper especially makes a detailed discussion and research in terms of marine functional zoning, examination and approval of the sea area use, user pays for the established rights and sea area use, and management of sea area resoruces as assets, proposes a number of new methods and trains of thought and established the applied model and system for the sea area use based on geographical space.Finally, on the basis of the research on the framework system of sea area use management, using such technologies as synthesis and integration and organically combining GIS, RS and GPS, the paper establishes the applied demonstration system for the management of sea area use with Ningbo as the demonstration zone, thus creating favourable conditions and technical support for the general spread and application of the system at all levels of oceanic administration throughout China. So far, this system has been disseminated and applied in over 30 coastal provinces, municipalities and counties in China.
