摘要
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 spatial analysis and simulation in spatio - temporal GIS. Based on analysis of the existing spatial and temporal reasoning methods,and combining with the prediction model of mining subsidence, a method of applying the theory of spatial and temporal reasoning to forecast the range and degree of mining damage in different time is put forward in this paper. In light of the needs of land reclamation in mining area, a database of dynamic land reclamation in agriculture, forestry, fisheries and construction was designed. The applied example in Renlou coal mine in the north of Anhui province showed that mine subsidence reasoning resuhs can be used as data source of dynamic land reclamation database.
