In order to support the rational distribution of oil spill emergency resources in coastal ports, a gravitational model and a social network analysis(SNA) method were used to construct an associated network model of oil spill emergency resources based on port oil throughput.The role of port based on oil throughput in the network were studied by using network characteristics such as network density and centrality to analyze the port oil spill emergency resource layout requirements. The results show that the network correlation degree is 1, the ports with higher individual network centrality are evenly distributed in the Pearl River Delta,Yangtze River Delta and Bohai Rim region, as the core position of the region.There is a reflexive relationship between the plates,and there are many internal correlations to form a cohesive subgroup. Therefore, the layout of port oil spill emergency resources should be integrated, and enhance the cooperation between the ports. And hierarchical grading plays the radiation role of central port .Regional division is used to optimize the construction of regional emergency response capacity.
