Abstract
Redevelopment of abandoned coal mine industrial sites (ACMISs) has been one of the critical research topics in recent years. The ecological system of ACMISs, which involves environmental, economic, and social characteristics, is an environment-economy-society (EES) composite system. Many factors with conflicting effects are involved in the sustainable development of this system. The matter-element analysis method presented in this paper can transform counteracting problems among influencing factors into compatible problems. This analytical approach leads to a reduction of the uncertainty of these influencing factors and provides a suitable research method to solve the complexity when selecting the most suitable reuse mode of the ACMIS. In this study, eight state-owned ACMISs in the suburbs of Beijing were investigated, and a suitability evaluation index system based on the EES conceptual framework was built. Targeting four reuse modes, including the residential area, the park, the scientific research and office campus, and the business district, we established a matter-element decision-making model to evaluate the priority of reuse mode selections scientifically. The results of our calculations show that the optimal reuse mode for the Qianjuntai, Muchengjian, and Huapogen ACMISs is the park; for the Da’anshan and Changgouyu ACMISs is the business district; for the Datai ACMIS is the scientific research and office campus; and for the Wangping ACMIS is the residential area. Since the suitability level of reusing the Anjiatan ACMIS in any of the four reuse modes is relatively low, it is recommended to reserve it for governmental strategically reserved open space. These real cases demonstrate that the research method is feasible and can be applied to reuse mode decisions for similar abandoned coal mines.
Highlights
China is one of the countries with the longest history of exploiting coal resources in the world
According to various planning documents, policies, and regulations, and in combination with the development positioning of abandoned coal mine industrial sites (ACMISs) of the Jingmei Group, as well as interviews with residents, we explored four reuse modes for ACMISs of the Jingxi Coal Mine based on the important functional positioning of the Mentougou and Fangshan Districts as the “ecological conservation area” of Beijing. e four reuse modes are the residential area, the park, the scientific research and office campus, and the business district
The ACMIS reuse project in western Beijing has been on the agenda, progress is relatively slow at present, and the reuse details need to be further defined
Summary
China is one of the countries with the longest history of exploiting coal resources in the world. E matter-element model employed in this study is a decision-making method developed based on extension theory [26]. It does not consider the optimization of quantitative relations but uses the matter-element transformation to reduce contradictions among factors. It transforms a contradictory problem into a compatible problem and abstracts a complex problem into a formal model, making the decision more objective and detailed. E purpose is to analyze quantitatively the decision-making of the reuse of ACMISs affected by the complex environment of environment, economy, and society and provide a scientific basis for adjusting the land use structure of mining wasteland Eight abandoned industrial sites in the Jingxi Coal Mine, which are located in the metropolis of Beijing where the contradiction between humans and land is very prominent, are selected as the research objects. e purpose is to analyze quantitatively the decision-making of the reuse of ACMISs affected by the complex environment of environment, economy, and society and provide a scientific basis for adjusting the land use structure of mining wasteland
