By the end of 2020, the main stream of the Yangtze River and its major tributaries will be completed within 10 km of each side of the treatment tasks. The upstream area restoration focus is to eliminate the potential disaster, prevention of soil erosion, restoration of vegetation; the midstream area restoration focus is slag management, prevention of pollution, restoration of vegetation; the downstream area restoration focus is to restore the ecology and repair the topography and landscape.

　　Recently, the General Office of the Ministry of Natural Resources issued a notice on the ecological restoration of abandoned open-pit mines along the Yangtze River Economic Zone, clearly requiring the comprehensive rectification of ecological damage to abandoned open-pit mines (including mining sites) along the Yangtze River main stream (including the Jinsha River in Sichuan and Yunnan, Yibin City, Sichuan to the mouth of the sea) and major tributaries (including the Min River, Tuo River, Chishui River, Jialing River, Wu River, Qing River, Xiang River, Han River, Gan River), and by the end of 2020, fully complete the task of treating abandoned open-pit mines within 10 kilometers of each side of the Yangtze River main stream and major tributaries.

　　Notice proposed to ensure safety, restore the ecology, taking into account the overall requirements of the landscape, solid development of the Yangtze River economic zone abandoned open-pit mining ecological restoration. First, according to local conditions, classification policy. Adhere to the principle of respect for nature, follow nature, protect nature, according to local conditions, according to the mine, take ecological restoration measures in line with the laws of nature, classification, scientific construction, to avoid causing new ecological damage. Second, to ensure safety, ecological priority. Adhere to the people-oriented, to ensure the ecological safety along the Yangtze River in the first place. Highlight the ecological function, systematic restoration, holistic protection. In areas with the conditions, taking into account the ecological landscape construction. Third, we must comprehensively coordinate and focus on breakthroughs. Ecological restoration of abandoned open-pit mines and ecological protection and restoration of mountains, water, forests, fields, lakes and grasses, etc. organic combination, in accordance with the requirements of territorial spatial planning and use control, based on the integrity of the ecosystem, the overall deployment. Adhere to the problem-oriented, distinguish priorities, priority deployment of the Yangtze River main stream and major tributaries within 10 km of each side, ecological problems of abandoned open-pit mine ecological restoration, based on key breakthroughs in the implementation of the overall promotion.

　　According to the notice, the Yangtze River Economic Zone abandoned open-pit mine ecological restoration priority tasks include: upstream areas of Yunnan, Guizhou, Sichuan, Chongqing abandoned open-pit mine to iron, manganese, bauxite, rare earths, phosphorus and other metals, non-metals, landslides, mudslides, cracks and other geological disasters are more developed, the restoration focus is to eliminate the potential disaster, prevention of soil erosion, and restore vegetation. In the middle reaches of Jiangxi and Hunan abandoned open-pit mines are mainly non-ferrous metals, rare earths, etc., and Hubei is mainly phosphate mines, with total phosphorus and heavy metal soil and water pollution problems, the restoration focus is on slag management, pollution prevention, and revegetation. Downstream areas of Anhui abandoned open-pit mines to iron, copper and other metals and limestone and other non-metals, Jiangsu, Zhejiang, Shanghai, mainly building materials mines, mountains, vegetation damage problems are more serious, the restoration focus is to restore the ecology and repair the topography and landscape.

　　The notice specifies four stages of ecological restoration of abandoned open-pit mines in the Yangtze River Economic Zone: First, mapping and verification. by June 2019, according to the Ministry of 2017 national mining environment remote sensing survey data, the region's abandoned open-pit mine situation verification, and the establishment of files. On the basis of verification, the province (district, city) as a unit to develop implementation plans, "a mine a policy" to establish a ledger, clear responsibility subjects, governance tasks, funding sources, governance time frame, etc.. The second is a comprehensive treatment. December 2020, the governance tasks will be decomposed at each level, grasp the implementation of the program. Governance should be based on ensuring the stability of the geological environment, repair and enhance the use of land resources, combined with the restoration of vegetation and mountain restoration, minimize the bare ground, increase the greening area. Third, supervision and inspection. Establish a dynamic supervision system, inspect and supervise the work carried out according to the progress, promptly inform the inspection and publicize it to the society, and take the initiative to accept supervision. The Ministry established a regulatory mechanism combining remote sensing monitoring and random sampling to supervise and inspect the progress of each place. National natural resources inspectors to carry out inspections of local governments to implement their responsibilities for ecological restoration of abandoned open-pit mines in the Yangtze River Economic Zone. Fourth, acceptance assessment. The acceptance process will be completed by the end of March 2021, and the overall assessment will be completed by the end of June 2021.

　　The notice emphasizes that the provincial natural resources departments should take the initiative to coordinate and promote local finance at all levels to coordinate the proceeds from the concession of mining rights for mine ecological restoration and other expenditures; ecological restoration of abandoned open-pit mines and ecological protection and restoration projects of mountains, water, forests, fields, lakes and grasses, geological disaster management, implementation of rural revitalization strategy, urban and rural construction land increase and decrease linkage, reclamation and utilization of abandoned industrial and mining land, ecological migration relocation and other organic integration; in accordance with In accordance with the principle of "who restores, who benefits", widely attract social capital to participate in the construction of "government-led, policy support, social participation, development-style governance, market-oriented operation" of the new model of mine ecological restoration. Central finance will be based on the provinces (autonomous regions and municipalities) restoration tasks and effectiveness, to give a certain amount of financial support.
