Coastal portresource is a kind of marine spatial resources and the material base for building port.Synthetical evaluation and effective utilization of coastal port reousrces is the premise to exploit the marine natural resources and develop regional economy.The study on the regional combination of coastal port resources is the prerequisite to develop and utilize coastal port resources more systematically.In this paper,the authors made a synthetical evaluation on the coastal resources in Liaoning province based on type of water front,quantity,quality,regional system,and currentstate of development.Espically,by applying AHP,the authors recived the array of the coastal portresources quality.Then, the basic theory of regional combination of coastal port resources was expounded.On the basis of the research above mentioned,the coastal port resources in Liaoning province were divided into four regional combination zones——the northern of the Yellow Sea,the southern tip of Liaodong Peninsula,the top of Liaodong Bay and the western tip of Liaodong Bay.The presentsituation,the main problems and the countermeasures ofevery regional combization zone were given.
