Abstract: Abstract: Determining a reasonable reclamation sequence of the large volume of mining wasteland can protect the ecological environment and support the land demand of economic development and industrial transformation in mineral resource cities. Taking the Mentougou district of Beijing city as the study area, a method of constructing an index system based on the factors influencing the reclamation sequence for comprehensive evaluation is presented in this paper. The evaluation index system, which includes four levels of ecological conditions, reclamation cost, geographical conditions, and economic and social factors, is built to determine the reclamation sequence of mining wasteland. Eight specific indexes are included: extent of damage, the grades of ecological risk, reclamation cost, traffic accessibility, distances from towns, regional population density, regional per capita GDP, and planning guide. A sequence-evaluation model based on GIS is established based on the above index system. Considering the needs of administrative management, the boundary map of administrative villages in Mentougou district and the distribution map of coal mining wasteland were superimposed, taking the village as the specific evaluation unit. The weight of each index is determined by an analytic hierarchy process. Quantification of each index is then made, followed by determination of the reclamation sequence of coal mining wasteland in the Mentougou district. The result shows that there are total of 45 villages in which coal mining wasteland need reclamation. Among them, sixteen villages need reclamation in the near future, where the area of coal mining wasteland is 121.94 hm2. These villages are mainly located in the southern mountains of the Mentougou district such as Datai, Yongding and Zhaitang town. These regions have a long history of coal mining, and the ecological system is severely damaged. In addition, they lie at or adjacent to the Mentougou new town. The population density is high. Nineteen villages need reclamation in the medium term, where the area of coal mining wasteland is 105.41 hm2. These villages are mainly located northwest of Qingshui town and south of Zhaitang, Tanzhe Temple and Wangping town. Coal-mining wastelands in these areas are scattered, and ecological damage is relatively light. Ten villages need reclamation in the long term, where the area of coal mining wasteland is 54.27 hm2. These areas mainly located in the mountainous areas. Coal mining activities are relatively small, and population density is low. By investigation, the result is consistent with the actual situation, which can provide theoretical support for the determination of the reclamation sequence of coal mining wasteland in the study area.
