Abstract: According to the ecological problems of the mining subsidence area in the east part of China, the paper introduced the farmland damage evaluation and grade of the mining subsidence and the productivity evaluation method of the reclaimed farmland in mining subsidence area. The paper provided the profile constructio n methods of the coal rejects backfill reclamation and the local soil backfill reclamation and the reconstruction technology of the regional agricultural landscape. The pa per introduced the construction technology of the secondary wetland biotope, vegetation landscape and artificial landscape in mining subsidence area and the water qu ality restoration method. The paper provided the project construction integrated technology with the survey of goaf, the stability evaluation of mining foundation, foundat ion reinforcement above goaf and anti- deformation building in mining subsidence area. The paper had an outlook on the research development orientation of the ecolo gical restoration technology in mining subsidence area.
