Research On Suitability Evaluation Of The Coastal Function

Content: The new situation for the Division of Coastal Zone features objectivity, science has put forward higher requirements. However, the Division of Coastal Zone features decision support analysis in China is still at the initial stage. For this coastal district decision support functions of the actual needs for coastal areas of functional nature, principles, requirements and work process, according to the spatial information system technical characteristics, study the establishment of a set of Coastal Zone assisted analysis of functional areas of technical methods And the geographical information system technology platform on the application of experiment, of which some of the key technical problems were more systematic analysis of the theoretical and applied research, with a view to the Coastal Zone functional areas to provide technical information and decision-making.This paper contains the following elements:First, the paper introduces the conception of coastal zone,the coastal zone appropriate function, summarize the suitability of the Coastal Zone features into the appropriateness of physical geography, economic and social appropriateness, suitability of policy planning, and the content of coastal areas suitable functional evaluation contains two parts :the individual functional suitability assessment and the order of the Coastal Zone features evaluation, which established a Coastal Zone functional area suitability assessment of the theoretical concept. And consider the principle of the marine function zoning and specific requirements, the combination of sea area, geography, resource and environmental characteristics, to the ocean function zoning suitability evaluation of the conceptual model.Second, depends on the characteristics and working process of the division of marine functional zones, combining with the actuality of the marine administration constructs the theory model of the suitability evaluation of the division of coastal functional zones.At last, in order to develop the model based on the result of operating the model and geographic information systems, the paper applies the model into practice, and makes the Jinzhou Bay and the Pulandian Bay in Dalian as research entities. The author collects a large number of research files and data of the two Gulf, and the research divides the coastal zone into five degrees:the most appropriate zoning for the area, More appropriate, appropriate for the area, the general area and not appropriate.
