The ro-ro passenger transportation channel of Qiongzhou Strait is an important channel for the transportation of people and vehicles entering and leaving of Hainan Island，and is also an important support for the construction of Hainan Free Trade Port.Through the systematic analysis of the characteristics of rolling passenger transportation and port resources of Qiongzhou Strait，the key issues of regional rolling passenger port layout are obtained.It is proposed that the rolling passenger terminal layout of Qiongzhou Strait should take the vehicle transportation demand in peak seasons as the main basis for the supply of terminal capacity.On this basis，according to the requirements of the overall plan for the construction of Hainan Free Trade Port and the needs of ensuring the transportation of passengers and vehicles entering and leaving the island，the layout idea of regional ro-ro ports and the recommended port sites are proposed.
