海域使用时空数据管理模式研究

随着时间的推移和对海域开发利用的变化以及对海域开发利用程度的提高，海域使用时空数据的动态管理将成为海域使用管理的重要内容。论文通过对海域使用数据的分析，提出了海域使用时空数据管理的模式，在原有海域使用信息的基础上增加时间信息和水深信息的管理，将海域使用数据的空间分类体系和相互影响关系与时空数据的动态管理有机的结合在一起。在空间层次上对海域使用进行重新的归类和补充，建立海域使用空间相互影响关系表，分析了海域使用时空数据的组成，设计了宗海时空数据库结构。按照海域使用时空数据管理模式，采用ESRI MapObjects的GIS图形软件包进行了开发试验，实现了海域使用过程中不同时间、不同空间层次数据的动态管理和时空分析。

Research on the Spatio-temporal Data Management Model of the Sea Area Use

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
