Study of index system on grade of marine in China

Marine,an indispensable part of our country,is the important platform for the exploitation of a variety of marine resources.It has long been the common case that marine has been taken advantage of free of charge,giving rise to a disorderly exploitation,an aggravated pollution and even the great loss of marine creatures.Therefore,the damaged ecological environment and lost ecological equilibrium prevent the sustainable development of coastal areas.Combining with "the differential land rent" in economics and "the AHP (analytic hierarchy process)" in operational research with the real conditions (such as the social,economic factors and basic facilities and natural resources) of 11 coastal provinces,cities and autonomous region,to make a theoretical research and grade the marine under our jurisdiction is attempted,thus making a solid foundation for the establishment of the tolling standard for the reimbursable utilization of the marine resources.
