时空推理是时空GIS空间分析与模拟的重要组成部分,在分析现有时空推理方法的基础上,结合矿区开采沉陷预计模型,提出应用时空推理来预测不同时刻矿区的采动损害范围及受损程度。针对矿区土地动态复垦数据库建设需求,设计了矿区农业、林业、渔业及建筑用地动态复垦数据库,皖北任楼矿的应用实例说明矿区沉陷时空推理结果可以作为土地动态复垦建库的数据源。
Spatial and temporal reasoning is an important part of spatio-temporal GIS spatial analysis and simulation. Based on the analysis of the existing spatio-temporal reasoning methods, combined with the prediction model of mining subsidence, it is proposed that spatio-temporal reasoning be used to predict the mining damage range and degree of damage . According to the requirement of dynamic land reclamation database construction, the dynamic reclamation database of agriculture, forestry, fishery and construction land in mining area is designed. The application example of Renlou mine in northern Anhui shows that the spatio-temporal reasoning result of mine subsidence can be used as the data of dynamic land reclamation source.
