基于GIS的采煤塌陷区土地复垦评价系统研究

Research of Mining Subsided Land Reclamation System based on GIS

土地复垦是恢复土地资源、保护生态环境、解决人地矛盾的一种有效措施。采用ArcEngine、ArcSDE、Oracle、面向对象开发语言Micirosoft Visual C#等技术,集成了土地复垦适宜性评价模型,地表变形预测模型、土方量计算模型、土地复垦经济效益评价模型,开发了采煤塌陷区土地复垦评价系统。系统实现了塌陷区土地信息的网络化、信息化管理,具有地图操作、地表变形分析、土方量计算、复垦适宜性评价、复垦效益分析等功能。

Land reclamation is an effective measure in recovering land resources,protecting ecological environment and solving the contradiction between people and land.This paper presents 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 for land reclamation.The system realized the information and network management about mining subsided land,provided the functions such as map handling,ground deformation analysis,land cube calculation,reclamation suitability evaluation and economic evaluation.
