1.
According to the nature/society and recyclable/non-recyelable standards,the in- put of emergy was divided into 4 categories,and the indexes of emergy——environment load rate(ELR)and the Emergy yield rate(EYR)——were calculated.
按照自然/社会、可再生/不可再生的标准将能值投入分成四类并列表计算能值指标:环境负载率(EIR)和能值产出率(EYR)。
3) net output
净产出;净产值;净产量
4) Net energy output
净能量产出
5) return on net worth
资产净值利润率
6) mergy yield ratio(EYR)
能值产生率
1.
Emergy yield ratio(EYR),emergy loading ratio(ELR) and emergy sustainable index(ESI) were selected to evaluate the sustainability and carrying capacity of sea cucumber ponds and several integrated fish and shrimp culture model.
通过比较刺参养殖池塘和几种集约化鱼类养殖池塘的能值产生率(emergy yield ratio,EYR)、环境负载率(emergy load-ing ratio,ELR)和能值可持续发展指标(emergy sustainable index,ESI),表明刺参养殖池塘单位能值投入的收益明显高于鱼类的集约化养殖模式,其可持续性和环境容纳量均较高。
