| 摘 要： | 分析了林权变更中时间信息、属性和空间变化信息,构建基于事件语义的时空数据模型,此模型用时间表、属性表和时空图分别描述林权变更过程中的时间信息、属性和空间变化信息,使用动作表描述林权变更过程中的空间变化类型.此模型使用SQL语言能够方便地进行时空信息查询,并能对某一状态林地的历史进行回溯.

| Abstract: | The time and space data model based on event semantics was established by analyzing time information,property change and spatial change in forest ownership change.The time information,property change and spatial change information are described by time table,property table,and time and space distribution chart of the model respectively.And the spatial change type during forest ownership change is described by the action table.The SQL language can easily inquire about time and space information and look back... |
