With the thriving development of high spatial resolution sensors, an increasing number of metric and sub-metric resolution remote sensing images are currently available, which allows for accurate geometrical analysis of objects at fine scales. Aimed to reveal the regional difference of coast land use in the Bohai Sea, series remote sensing images of HJ-1ACCD obtained in July of 2013 were employed to monitor land use in 5 km coastal zone of 13 regions around the Bohai Sea. Some evaluation index, such as dominant land use type, land use dominant index and land use intensity index were established to evaluate the regional difference of land use in the coast zone. The result shows: there exist obviously regional differences in coast land use around the Bohai Sea. Some regions such as Huludao and Yantai are typical farmland landscape. Some regions such as Dongying and Panjin are typical reed wetland landscape, While Cangzhou is typical fishpond landscape, Weifang and Binzhou are typical salt pond landscape. Land use in coast of Huludao, Yantai and Weifang are single dominated structure, the dominant land use type are farmland in Huludao and Yantai. It is salt pond in Weifang. Their dominant index is all above 0.34. Land use in coast of Tianjin, Qinhudao and other 8 regions are dual structure. The dominant index of dominant land use type ranged from 0.10 to 0.30. The land use intensity index is biggest in coast of Tianjin and Cangzhou with value 2.15 and 2.12, respectively.
