Research on Ecological Reconstruction of Subsided Land in Mining Area Based on Location Theory Taking Pingdingshan City as a Case

The subsided land of mining area is not only the land and ecological environment damage caused by the exploit of mineral resources but the very important land resource to sustainable development of the resource-based cities. A view is put forward that the ecological reconstruction of collapsed land of the resource-based cities should be planed based on its zones. Taken the Pingdingshan City as a case, the zoning ecological reconstruction plan of the collapsed land was made based on location theory, being accord to the urban function zones and development planning. The zoning plan will change the spontaneous agricultural reclamation to integrity of multi-use and from the single benefit of agriculture to the multi-gain of ecology and economy.
