摘要: 提出了反映火电厂生态工业园特点的能值评价指标:能值产出率PEYR和能值投资率PEIR考虑了园区各成员的共同贡献,即PEYR= =1(Fi+Ri+Ni)/ FiPEIR= Fi/ Fi/ (Ni+Ri);环境负荷率PELR和能值可持续指标PESI考虑了火电厂生态工业园节省的不可再生能源、可再生能源、投入能值和减少的环境负荷,即PELR= Fi/F'PESI=PEYR/PELR.以朔州火电厂生态工业园为案例进行了能值分析,结果表明,该能值评价指标能全面度量火电厂生态工业园及其可持续性.

Abstract: In this paper,new emergy indices for the material circulation utilization and energy cascade utilization were presented to evaluate the emergy of power plant eco industrial park.The common contribution of the members in power plant eco industrial park should be accounted for emergy yield ratio (PEYR) and emergy investment ratio (PEIR),namely, PEYR= (Fi+Ri+Ni)/ Fi and PEIR= Fi/ (Ni+Ri).Saved renewable and nonrenewable resources and purchased resources and decreased environmental load should be accounted for environmental loading ratio (PELR) and index of sustainability (PESI),namely, PELR= Fi/F' and PESI=PEYR/PELR.Case analysis on the Shuozhou power plant eco industrial park showed that new emergy indices were practical in evaluating the power plant eco-industrial park.

Key words: Eco-industrial park, Power plant, Emergy, Sustainability
