【摘要】：针对矿区地质环境污染面积动态变迁和实时监测问题,首先根据TGIS中的时间属性表达特性,分别将时间粒度表达和变粒度时空存储因子设计与现有的动态多级基态修正模型进行综合集成表示,提出了一种动态多基态变粒度的修正模型,实现了时间粒度动态变化过程中多基态自动确立问题;其次结合某矿区地质环境面积变迁的时空数据特征,分别设计了时空数据库的五库结构和数据库组织结构,实现了矿区地质环境面积变迁时空数据库的逻辑和物理结构设计;然后通过结合TGIS和视频播放器原理,实现了矿区地质环境面积变化场景的回放,并采用空间数据库查询语句实现了地质环境面积变化的超前预演;最后以某矿区地质环境数据为例,实践表明:动态多基态变粒度的修正模型可实时监测矿区地质环境类型面积的变迁过程,增加了复垦区域的面积,实现了矿区地质环境面积变迁数据的存储、再现和未来变迁的预演。
[Abstract]:In order to solve the problem of dynamic change and real-time monitoring of geological environment pollution area in mining area, firstly, according to the time attribute in TGIS, the characteristics are expressed.The time granularity representation and variable granularity spatio-temporal storage factor design are integrated with the existing dynamic multilevel ground state correction model, and a dynamic multi-ground state variable granularity modified model is proposed.The problem of automatic establishment of multi-ground state in the process of dynamic change of time granularity is realized. Secondly, the five database structure and database organization structure of spatio-temporal database are designed according to the spatial and temporal data characteristics of geological environment area change in a mining area.The logical and physical structure design of the spatio-temporal database of geological environment area change in mining area is realized, and the playback of the changing scene of geological environment area in mining area is realized by combining the principle of TGIS and video player.Finally, the geological environment data of a mining area is taken as an example.The practice shows that the modified model of dynamic multi-ground state variable granularity can monitor the change process of geological environment area in real time, increase the area of reclamation area, and realize the storage of the change data of geological environment area in mining area.A preview of reproduction and future change.
