Under the influence of the COVID-19 pandemic and other external factors，container ports of Shanghai，Shenzhen，Guangzhou and other parts of China are experiencing congestion，which has become a concern of relevant departments and the industry on the adaptability of container terminals. After analyzing China’s container shipping demand and coastal container terminal capacity supply，we evaluate the basic situation of container terminal adaptability and put forward suggestions on the container terminal planning and construction according to the new development situation of container ports in the future. The results show that the capacity of container ports in the Bohai Rim，the Yangtze River Delta and the southwest coastal area is appropriately tight，while it is appropriately surplus in the Pearl River Delta and the southeast coastal area. Considering the development trend of the transportation demand，container ship type，COVID-19，etc.，we shall further optimize the container port layout and accelerate the construction of container terminals in regions with relatively tight port capacity. In addition，we should explore new technologies and models for the development of deep-water terminals in hub seaports and innovate the evaluation methods for terminal adaptability，which can better support the development of the national economy of China.
