The Study Of Comparison And Relationship Between The Division Of Marine Functional Zones And The Division Of Marine Main Functional Zones

Both the division of marine functional zones and the division of marine main functional zones are of the work which divides our country's sea aera according to different factors .Analysis of the differences and relationship between the division of marine functional zones and the division of marine main functional zones is the basis which can make the two work to paly their roles in our country's marine cause fully .Additionally, the division of marine functional zones is earlier than the division of marine main functional zones. So,the theoretical results, zoning method and experience of it can be applied to the the division of marine main functional zones according to the comparison between the two work.The paper studies the division of marine main functional zones referring to the theoretical results of division of national main function zones and giving full consideration to characteristic of the ocean, compares the division of marine functional zones with the division of marine main functional zones to reveal their differrences and relationship, proposes establishment of decision supporting system which combines the division of marine main functional zones with the division of marine functional zones. The paper consists of four parts:The first part studies the division of marine main functional zones through referring to the theoretical results of division of national main function zones and giving full consideration to the special nature of the ocean, summarizes the connotation, features and significance of the division of marine main functional zones, enriches the division of marine main functional zones's theoretical system.The second part compares the division of marine functional zones with the division of marine main functional zones in the eight sections as follows:purpose , guiding ideology, principles, classification and grading system, variability, scope, means of implementation, the relationship that is needed to coordinate.The third part reflects the relationship between the division of marine functional zones and the division of marine main functional zones in compiling,drafting marine development planning and marine utilization and management conducting.The division of marine functional zones can provide the basic data , theories, methods and experience for the division of marine main functional zones . The division of marine main functional zones can promote in-depth work for the division of marine functional zones.The fourth part proposes the establishment of decision supporting system working in GIS environment which combines the division of marine main functional zones with the division of marine functional zones.The system is composed by four parts: database, indicators management part, model management part and evaluation part.The system will make scientific and objective results for the division of marine main functional zones and the division of marine functional zones available to policy-makers, provide services for drafting marine development planning and conducting marine utilization and mangaement, promote the cimbination between the division of marine main functional zones and the division of marine functional zones in the actual work.
