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 = sigma(i = 1)6 (Fi + Ri + Ni)/sigma(i = 1)6 Fi and PEIR = sigma(i = 1)6 Fi/sigma(i = 1)6 (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 = sigma(i = 1)6 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.

摘要

本文提出了用于物质循环利用和能量梯级利用的新能值指标，以评估电厂生态工业园区的能值。电厂生态工业园区成员的共同贡献应通过能值产出率（PEYR）和能值投资率（PEIR）来衡量，即，PEYR = σ(i = 1)6 (Fi + Ri + Ni)/σ(i = 1)6 Fi 以及 PEIR = σ(i = 1)6 Fi/σ(i = 1)6 (Ni + Ri)。节省的可再生和不可再生资源、购买的资源以及降低的环境负荷应通过环境负载率（PELR）和可持续性指数（PESI）来衡量，即，PELR = σ(i = 1)6 Fi/F' 以及 PESI = PEYR/PELR。对朔州电厂生态工业园区的案例分析表明，新能值指标在评估电厂生态工业园区方面是实用的。
