Research of Mining Subsided Land Reclamation System Based on GIS

Land reclamation is an effective measure in recovering land resources, protecting ecological environment and solving the contradiction between people and land. This paper adopts ArcEngine, ArcSDE, Oracle, Micirosoft Visual C# and other technologies to develop mining subsided land reclamation system which integrates reclamation suitability evaluation model, ground deformation prediction model, land cube calculation model and economic evaluation model. The system realized the information and network management about mining subsided land, provided the functions such as map operation, ground deformation analysis, earth volume calculation, reclamation suitability evaluation and economic evaluation. It can be used to help decision maker choose and plan their activities more effectively and scientifically to match situation of land reclamation and ecological restoration.
