并对刺参池塘能值的各部分分布进行了分析.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

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.
Abstract
The economic income and environmental sustainability of sea cucumber(Apostichopus japonicus) culture in northern China was analyzed using the emergy approach.Schematic diagram of sea cucumber ponds with emergy symbols was built to analyze the emergy of different parts in sea cucumber earthen ponds.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.The results showed that the EYR in sea cucumber culture was higher than that in integrated fish and shrimp culture
and sea cucumber culture gained higher sustainability and carrying capacity.
