Summary This paper reviews research and management of remediation and restoration of mined land in China aiming at promotion of theoretical innovation and technological development in this research field of China. The review is made mainly in view of soil science and ecology in mined land, including the following seven sections: (1) the development background during last 50 years; (2) the limitation factors for remediation and restoration; (3) physical and chemical remediation of degraded soil; (4) phytostabilisation and phytoextraction of metal polluted soil; (5) microbial animal enhanced remediation of polluted and degraded soil; (6) the technological requirements for utilization and management of remediated mined land; and (7) future research and development in field of mined land remediation and eco restoration in China.
