Abstract: In this study, we use the system analysis and optimization of GIS spatial analysis study the allocation of resources of port. First, we use optimize given resource allocation model which of yard space analysis; Second, give the berths dynamic resource allocation optimization function; then GIS spatial analysis is given in the port resource optimization. Port for optimal use of resources space and impact factor model for quantitative analysis and visualization used spatial analysis model which provides effective analytical approach to role and explores the mechanism. Finally, we give application examples. Based on the theoretical analysis and comparative analysis we achieve optimal allocation of resources and development plans in coastal port, which provides a theoretical basis and empirical basis in port resources study.
