基于DPSIR模型的黄金行业绿色矿山建设综合评价研究

Comprehensive Evaluation of Green Mine Construction in Gold Industry Based on DPSIR Model

针对当前绿色矿山评价过程中存在的主观因素影响较大的问题,以黄金行业为例,基于驱动力—压力—状态—影响—响应框架模型,从5个层面构建指标体系。结合主客观组合赋权法确定指标权重,引入TOPSIS和耦合协调度模型定量评价绿色矿山建设时空演化过程及子系统间的耦合协调性,分析得出影响企业绿色矿山建设的主要障碍因子,为企业绿色矿山建设改进提供对策建议。通过对陕西某金矿的实际案例分析,验证了模型的适用性。本研究系统整合了绿色矿山评价指标,完善并优化了绿色矿山建设评价方法,使评价结果更加公平可靠,为推进矿山可持续发展提供了有效途径。

At present,the evaluation system and methods of green mine construction in the gold industry are not perfect.On the one hand,in most studies,when establishing the index system,the internal relations between indicators were ignored,and only the influencing factors related to green mine construction in general were listed.On the other hand,most of the models lack completeness when establishing the evaluation model,they only evaluate the construction results at a certain time point without showing the change trend of the construction process.Based on the framework model of driving forces,pressure,state,impact and response,the evaluation index system of green mines in gold industry was constructed to express the internal relationship between indicators more intuitively.In building the evaluation model,the subjective and objective combination weighting method was introduced so as to make the index weight meet the subjective expectations of the decision-makers and the objective judgment requirements of the inconsistency between the indicators.The TOPSIS coupling coordination model was introduced to quantitatively evaluate the space-time evolution process of green mine construction and the coupling coordination among subsystems,and the main obstacle factors affecting the green mine construction of enterprises were analyzed,providing guidance countermeasures for the improvement of green mine construction of enterprises.Through the analysis of an actual case of a gold mine in Shaanxi Province,it is concluded that the green mine construction of the general system of the mine and the coupling and coordination degree between the subsystems are steadily increasing,the construction of each subsystem is fluctuating.The industrial production capacity(C_(1)),the energy consumption(C_(5)),the mine environment(C_(9)),and the mineral processing(C_(11))are the main obstacles in the construction process,which are consistent with the actual construction of the mine,and the applicability of the model is verified.The evaluation index system established in this paper clarifies the function mechanism of each index of green mine construction,which helps enterprises flexibly respond to a series of related factor changes caused by a certain index change.The established evaluation model improves the defect of subjective influence on the evaluation results in the traditional evaluation,highlights the internal connection and coordination between the evaluation indicators,makes the evaluation process and results more fair and reliable,and provides an effective way to promote the sustainable development of the gold industry mining industry.
