The dynamic management of the sea area use spatio-temporal data is going to be highlighted, with the changes of the development of the sea area use and the improvement of the utility level of the sea area Through the analysis of the sea area use data, this paper derived the spatio-temporal data management model Besides the traditional sea area use information, the temporal information and bathymetric information are added in this model This model also combined the dynamic management of the spatio-temporal data with the data's spatial classification system and the interactions In the spatial layers of the sea area, the categories of sea area uses are re-classified and supplemented and the spatial interactions table is established Focusing on the components of the spatio-temporal data of the sea area use, the spatio-temporal database structure is designed According to the concept of this new model, by using the GIS software package of ESRI MapObjects, we have developed the methods which made it possible to dynamically manage the multi-dimensional spatio-temporal data in the sea area use Also the methods made the spatio-temporal analysis of the multi-dimensional spatio-temporal data in the sea area use come true
