煤矿区绿色低碳评价指标构建及应用

Construction and application of green and low-carbon evaluation indicators for coal mining areas

  • 摘要: 煤矿矿区是煤炭生产的重要基地,对当地经济和能源供应具有重要意义。在我国能源开发和环境保护中,矿区规划占据着举足轻重的地位。随着全球能源格局的变化以及我国提出的“碳达峰、碳中和”战略目标,煤矿矿区的规划不再仅仅局限于资源的开采,更要注重生态环境的保护与修复,以及矿区经济的可持续发展。因此,有必要将“双碳”规划的内容纳入到矿区总体规划中,以此来引导煤炭行业的可持续发展,并支持国家的“双碳”战略目标。为了进行矿区“双碳”规划,首先需要对矿区的碳排放现状进行详细评估,从而为“双碳”规划提供科学依据。以煤矿矿区为视角,提出了“三步法”构建评价指标,即综合分析法初选指标、社会网络分析法补充指标和模型法校核指标。该指标体系包含7项一级指标和36项二级指标,引入模糊变量隶属度函数,建立模型对二级评价指标量化计算,采用逐层模糊综合评价法,对矿区绿色低碳度进行评价。以宁夏积家井矿区为案例,应用本研究的评价体系进行实证分析。结果表明,积家井矿区在绿色低碳发展方面尚处于较低水平,但同时也显示出巨大的改善潜力。针对评价结果,提出矿区未来应当注重合理利用土地资源,加强土地复垦,强化生态重建与保护措施,为矿区的绿色低碳转型提供了可行的路径。

     

    Abstract: Coal mining areas serve as pivotal bases for coal production, holding significant importance for local economies and energy supply. In the development of China’s energy and environmental protection, the planning of mining areas plays a crucial role. With the changing global energy landscape and China’s strategic goals of peaking carbon emissions and achieving carbon neutrality, the planning of coal mining areas transcends the mere extraction of resources, emphasizing the protection and restoration of the ecological environment, as well as the sustainable development of the mining economy. Therefore, it is imperative to integrate the content of “dual-carbon” planning into the overall planning of mining areas to guide the sustainable development of the coal industry and support the national “dual-carbon” strategic objectives. To implement “dual-carbon” planning for mining areas, a detailed assessment of the current carbon emissions status of the mining areas is required to provide a scientific basis for “dual-carbon” planning. This study, from the perspective of coal mining areas, proposes a “three-step method” to construct evaluation indicators, namely, the initial selection of indicators through comprehensive analysis, supplementation of indicators via social network analysis, and verification of indicators using the model method. The indicator system comprises seven primary indicators and thirty-six secondary indicators, incorporating the fuzzy variable membership degree function to establish a model for the quantitative calculation of secondary evaluation indicators and employing a hierarchical fuzzy comprehensive evaluation method to assess the green and low-carbon status of mining areas. Taking the Ningxia Jijiajing mining area as a case study, this study applies the evaluation system for empirical analysis. The results indicate that the Jijiajing mining area is currently at a lower level of green and low-carbon development but also shows great potential for improvement. In light of the evaluation results, this study suggests that the mining area should focus on the rational utilization of land resources, strengthen land reclamation, and reinforce ecological reconstruction and protection measures, providing a viable path for the green and low-carbon transformation of the mining area.
