In this paper, we took the terrestrial part of a 30-km buffer zone of coastline as the study area. Land use data in 2005 obtained based on Landsat images were available, and based on the spatial analyst techniques in GIS and Zonal Statistics Method, the Dominance Degree and Land Use Degree Index were calculated for the study area and its 15 sub-zones. Then, the structures and spatial patterns of land use in coastal zones were analyzed. The result shows that, farmland, forest, built-up and residential areas are dominant land use types in Chinese coastal zones; and remarkable sea-land gradient characteristics of land use can be found because following the changes of distance to coastline, the quantity structure and spatial patterns of land use change correspondingly. Water body, built-up and residential areas show the most notable seaward characters. There is much higher intensity of land use in coastal zones than that in the whole country and coastal provinces, and the zone of 2-6 kilometers away from the coastline has the most prominent land use intensity. Furthermore, there are remarkable administrative differences and altitudinal differences of land use in Chinese coastal zones.
