Research On The Change Of Demands On Sea Of Marine Industry Based On GIS

In this paper,the geographic information system spatial analysis method is used for technical support,use the superposition analysis,buffer analysis,time series forecasting model and other methods,select the 2.0 version and 3.0 version of the marine functional zoning as the research object,to study on the Bohai Sea,the Yellow Sea,the East China Sea(Liaoning Province,Shandong Province,Fujian Province),this paper analyzes the change of spatial and temporal characteristics of functional areas of marine fnctional zonation,and analyzes the change of sea demands in major marine industries.This paper mainly makes the following four aspects of research work:Firstly,the functional classification system of the two-stage marine functional zoning for version 2.0 and version 3.0 was sorted out to determine the specific functional connotation of the first and second class functional areas and the dominant marine industry activities defined in the functional area,Define the association between marine functional zoning and industry use.Secondly,using GIS spatial analysis technology and data processing method,the original ocean function zoning data is vectorized and converted into spatial data.The number of functional zones of two levels of marine functional zoning in Liaoning province,Shandong province and Fujian province is established respectively,Area and coastline ratio,and find out the types of sea use in the functional areas with obvious changes in the two periods.The land space structure statistical analysis method and the land type transfer matrix of regional economics are used to analyze The transfer and flow of each class within the functional area.Thirdly,the changes of plaque changes in the functional areas were obtained by further in-depth analysis of the larger agricultural and fishery areas,port shipping areas,industrial and urban sea areas and marine natural functional areas.Marine fisheries,port shipping industry,coastal industry and other related industries involved in the analysis of socio-economic factors,to explore the marine industry with sea demand changes and the social and economic reasons behind the sea layout,and qualitative and quantitative methods to predict the future trend of industry with the sea;Analysis of industry conflicts with the sea and the allocation of resources for the new round of marine functional zoning functional areas to provide the basis for the work of support.Fourthly,the influence of the continental coastline on the marine functional area and the radiation range between the coastal cities and the marine industry were analyzed by using the buffer analysis method.The spatial clustering degree of the sea-related industry was analyzed by combining the plaque fragmentation index and the global Moran index,From the perspective of economies of scale and scope of economic analysis of marine industry layout and agglomeration characteristics.In this paper,the use of geography database and the actual economic data related to the sea-related industry,not only can use the rich data to show the marine industry spatial pattern changes and industry development of the situation,but also through the map way to visually show the state of marine industry agglomeration,,With the sea and other changes in the process.This paper will provide the basic theoretical support for the development of the marine functional zonation based on the ecosystem of the 4.0,and guide the marine industry to concentrate the intensive use of the sea and ensure the sustained and healthy development of China's marine resources and environment.
