Abstract: To explore the dynamic changing features of land use in harbor area driven by port construction, the land use patterns in Dagushan area of Dalian in 1993, 2000, 2007, and 2014 were extracted as a case study. The ecosystem service values of different terms are assessed. In the case study, the influential factors of the land use and ecosystem service value changes are analyzed, and the spatial patterns of port-dominated coastal regions are summarized. Results show that the increase of construction land is basically consistent with the speed of port development, and the construction land has been the largest land use type in Dagushan area. Meanwhile, the proportion of ecological land decreases significantly, which results in the insufficient space for construction expansion and the great pressure on ecological environment. It is suggested that the protection of ecological land, in particular, forest land and water body shall be strengthened.
