Fuzzy comprehensive evaluation of land reclamation suitability in mining subsidence based on GIS

In order to make full use of mining subsidence areas, a fuzzy comprehensive evaluation method on the land reclamation suitability is used. According to the three directions of land reclamation of agriculture, forestry and pond, we choose proper evaluation elements and weights, and then obtain the structure of land reclamation suitability of this coal mining subsidence as a result which provides a basis for reclaiming the subsidence area appropriately. Combined with GIS, a land suitability evaluation result map of this coal mining subsidence is drawn.
