Resource Utilization and Sustainability Evaluation of Pumped Storage Power Station Construction System Based on Emergy Analysis
摘要
Abstract
To investigate the resource utilization efficiency and eco-economic sustainability of pumped storage power station construction sys-tems,a systematic evaluation model is established based on the emergy analysis method.The emergy flows of each component within the sys-tem are quantitatively assessed,and sensitivity analysis is adopted to identify key influencing factors.The results reveal that the relationship between system resources and power station construction presents a pattern of"support-constraint".Industrial auxiliary emergy(accounting for 57.2%)serves as the fundamental support for construction,among which diesel oil and asphalt(totaling87.1%)dominate the ecological costs.There exists an explicit weight hierarchy among system resources,and energy input acts as the decisive factor,whose variation exerts the most significant influence on the emergy sustainability index(ESI).The whole system achieves a medium sustainable development level with ESI=2.07.An optimization path of"priority of energy efficiency-substitution of key materials-upgrading of equipment and technology"is proposed to improve its sustainability.The research outcomes can provide quantitative support for the ecological management of pumped storage power stations,and possess important practical value for promoting the green development of clean energy infrastructure.关键词
