Effects of mining subsidence on niche suitability of cultivated land

摘要：

　　Surface subsidence caused by coal mining had an influence on the normal production of cultivated land.The theory of niche was used in this study to construct the niche suitability evaluation model of farmland in mining subsidence,and it can quantitatively evaluate the decline in the quality of cultivated land.Reasons for farmland damages were discussed from the ecological point of view.Through the actual cases,the effect and spatial distribution of cultivated land niche suitability were analyzed in a mining subsidence area.The method provided an effective tool for land reclamation and ecological reconstruction in the mining area.
