Progress and prospect of research on land reclamationplanning and design in mining area

In order to analyze the current situation of land reclamation planning and design in mining area and explore the future development trend, the main development courses of land reclamation planning and design were reviewed by citing the relevant literatures, academic works, technological achievements at home and abroad. We summarized the progress of system and scale of land reclamation, suitability evaluation, land use structure and layout optimization, concept and mode of reclamation planning, planning and design of key reclamation projects. Comparing with foreign countries, the dynamic pre-reclamation planning and design of coal mining subsidence land in china leaded the international. However, there were still some deficiencies in land reclamation planning and design, for examples, land reclamation was weakly combined with the mining planning, the purposes of reclamation were so focused on farmland that less involved in protection and leisure planning mode, geomorphic reclamation was still in its infancy and rarely applied. Furthermore, considering the development of national society and international trends, we prospected the scientific advances to promote the scientific development of land reclamation planning and design, including establishing intelligent decision-making system, promoting mining-reclamation integration and realizing multi-dimensional virtual based on the cloud platform. Moreover, researchers should pay more attention to differences, coordination and biodiversity conservation of land reclamation planning and design.
