Abstract: In order to promote the rational utilization of marine resources and the effective allocation of sea area,it is important to get a better understanding of the changing trend of sea area use scale and structure. In the current study,temporal-spatial differences of sea area use scale and structure in China from 2002 to 2015 were analyzed by using the centralization index of Lorentz Curve,Information Entropy,Equilibrium degree and Dominance degree. The changing trend of sea area use was predicted by using R/S method,and the main factors influencing sea area use changes were also explored. The results could be concluded as follows：（1）the scale of nationwide sea area use has increased continuously with a high degree of spatial agglomeration. The newly increased sea area use scale has been rolling up and the spatial differences of sea area use was enlarged during the study period. The sea area use is mainly concentrated in Liaoning,Shandong and Jiangsu provinces. （2）The sea area use of fisheries,industry and communication accounts for a high proportion. The relative growth rate of sea area use speeded up in most categories （with the exception of sewage dumping and other types of sea area use）. The dominant degree of sea area use structure first decreased from 2002 to 2004 and then increased after 2004. The sea area use structure was approaching to an ordered state based on reducing information entropy. Ocean development may negatively impact the marine environment through declining sea water quality and disrupting ecological balance. （3）In the next 14 years （2016—2029）,sea area use scale will keep the same changing trend as the past and will still be growing in the whole country as well as in coastal provinces of China. The categories of sea area use scale such as industry,communication,submarine engineering and special use will keep increasing,while those such as fishery and tourism & recreation will slow down and the sea area use of sewage dumping will present a downward trend. （4）The scale and structure of sea area use and their changes have been influenced by many factors including the location,history,economy,land and policy of the local administrative division where the sea area is distributed,which may have negative impacts on the marine ecological environment. The results of the current study will provide reference value and guidance significance to formulate administrative policies and relevant optimizing strategies for sea area use.
