Abstract: In order to promote the construction of national ecological civilization,Ministry of Natural Resources of the People′s Republic of China and provincial natural resources departments have issued relevant policy documents in succession, making it clear that ecological restoration will be carried out on legacy abandoned mine in key areas such as the Yangtze River Basin. In order to analyze the problems existing in the ecological restoration of legacy abandoned mine and summarize its ecological restoration model,based on the field investigation of ecological restoration of nearly 1 000 legacy abandoned mine in Sichuan Province,combined with relevant national and local policy documents,the connotation of ecological restoration of legacy abandoned mine in the trunk stream and tributaries of the Yangtze River is elaborated,the main ecological restoration modes of stope slope,stope bottom platform and industrial square,and waste dump are induced,the classic cases of ecological restoration are summarized,and the existing problems in the process of ecological restoration,such as incorrect geological patch range and geological direction,unclear concept of cultivated land,focous on geological hazard engineering but less to ecological restoration engineering,and unreasonable arrangement of engineering measures are analyzed. It provides reference for the ecological restoration of legacy abandoned mine in the future.
