Abstract: Land and ocean are the ecosystems of mutual interaction and restriction, the realization of marine pollutants control depends on the situations of terrestrial pollution, and the total amount allocation of terrestrial pollutants should also consider their affects to ocean environment.Considered from the environmental management point of the "Overall planning of the land and the sea", and also their mutual interaction and restriction, This paper puts forward a total amount control thinking of "Sea area-Watershed-Administrative Region" and an allocation method of "Prime allocation-Assessment-Reallocation", based on the fairness principle.This paper adopts classic fairness methods, such as Analytic hierarchy process, Entropy value method, Gini coefficient method, and use them in the Liaodong Bay and Liao River Watershed total amount allocation of COD pollutants.The point of this paper can provide decision-making basis for ocean environmental departments.
