Land reclamation is a complex and systematic project. The traditional modes of working and management cannot increasingly meet the needs of current land reclamation engineering. The aim of establishing the land reclamation information system is to make out the reasonable plans and scientific management of land reclamation engineering. In this paper, the author firstly introduces the application of GIS in land reclamation, and then explains the necessity and objectives of establishing the land reclamation information system for mining area, finally provide main functions of the system, the application models and implementing methods of major functions of the system. The establishment of the system can improve the efficiency and rationality of land reclamation planning, and is favorable to promote the development of land reclamation.
