摘　　要：运用能值理论,在对福清宏峰泰鲍鱼养殖基地各项能值流动情况进行核算的基础上,构建起能值评价指标体系,对该养殖基地的经营情况、环境影响及可持续性进行评价和系统敏感性分析.结果表明:鲍鱼养殖系统绝大部分能值投入来自于外部购进的不可更新资源能值,且投入产出比较低.鲍鱼养殖对周边环境造成了较大的压力,且自身发展的可持续性较低.通过提高可更新资源能值比例和降低不可更新资源能值比例可以显着降低系统的环境压力,提高可持续性;降低不可更新资源能值比例还可以提高系统整体生产效率.研究结果为促进鲍鱼养殖业健康可持续发展提供了一定科学依据.Based on the emergy analysis, analysised the account of various emergy flows in abalone aquaculture of Fuqing-Hongfeitai abalone breeding base, builded up emergy evaluation in- dex system to evaluate the operation situation, the environmental impact, the sustainability and to analysis the system sensitivity of the abalone aquaculture. The result shows： The vast major of emergy input of the abalone aquaculture system is from purchase nonrenewable resource emergy out- side, and the input-output ratio is low. The abalone aquaculture coused great pressure on the sur- rounding environment, and the sustainability is relatively low. Increasing the renewable resource emergy ratio and reducing the nonrenewable resource emergy ratio can reduce the environmental pressure of the system significantly, and improve sustainability, moreover reducing the nonrenew- able resource emergy ratio can improve the overall system efficiency. The result provided the certain basis for promoting the sustainable development of the abalone aquaculture.
