矿区土地动态变化时空数据模型设计

Design of spatio-temporal data model on land dynamic changes of mining area

在地下开采活动过程中,矿区地表地理实体具有明显的时空变化特征,本文是在分析现有时空数据模型的基础上,针对矿区采动受损地表实体的损害及修复,按照面向对象的思想,将矿区地面实体分为点、线、面三类,分别对各种受损对象设计了复垦区时空数据模型,在此基础上可以进一步构建矿区土地复垦时空数据库。

In the process of underground exploitation, the corresponding geographical entities on the ground express the distinct temporal and spatial variation features in the mining area. Based on the object-oriented idea, considering the current spatio-temporal data models, the damaged ground entities and their restoration, the ground entities were summarized as point class, polyline class, and polygon class in this paper. The spatio-temporal data models were designed according to different ground entities in the reclamation area, and the spatio-temporal database of the land reclamation could be built based on these models.
