Progress in Researches on Evaluation of Quality of Cultivated Land Consolidated from Coal Mining Subsided Land

The evaluation of consolidated cultivated land quality can provide basic information for how to perfect the program of land consolidation,as well as a reference for the dynamic monitoring of farmland quality in mining area.Based on the consultation and analysis of related literature,we can conclude that:firstly,most scholars focus on soil consolidation, while consider little about land use and economic condition. Secondly, foreign scholars usually use crop yields to judge the success of land consolidation, while domestic scholars have been evaluated the quality of consolidated cultivated land synthetically from several aspects,such as soil fertility,soil environmental quality,and farmland infrastruture conditions.Specifically,most of the evaluations are static,and indicators are different.Besides,the quality of consolidated cultivated land is generally low,and it lacks systematic research on technologies for improving quality of cultivated land consolidated from coal mining subsided land.It is concluded that future researches should focus on establishing scientific and feasible evaluation system to realize comparison of quality change in the dynamic course of “undisturbed — subsided — consolidated” cultivated land in coal mining areas, as well as technologies for improving quality of cultivated land consolidated from coal mining subsided land.
