The high-quality development of the waterborne transportation industry requires that the use of port shoreline must be specialized，economical and intensive.However，there is no recognized calculation method or measurement for the intensive utilization degree of port shoreline，and it is difficult to quantitatively analyze the degree.Starting from the meaning of intensification，this paper puts forward the input index and output index to measure the shoreline，and gives the meaning and formula of the intensive utilization degree.Taking the shoreline utilization in two operation areas of a port in the middle and lower reaches of Xijiang River as an example，the indicators and the intensive utilization degree of shorelines are calculated，and the results are in good agreement with the actual situation.The measurement method for the intensive utilization degree of port shoreline can evaluate the current shoreline or be applied to the port shoreline planning，which provides guidance for shoreline planning and development，gives full play to the resource advantages of each shoreline，and maximizes its value.
