摘    要:以能值理论为基础,选择舟山市东极贻贝养殖生态系统为研究对象,在定量分析贻贝养殖生态系统的物质流和能量流的基础上,通过建立能值评价指标体系,综合评价东极贻贝养殖对环境的影响及其可持续性。结果表明:东极贻贝养殖生态系统的太阳能值转化率TR为3.35E+09sej/g,环境负荷率ELR为0.45,能值产出率EYR为3.22,能值投入的生产效率PEEI为9.60E-10g/sej,系统可持续发展指数ESI为7.16。最后将其与其它四种养殖系统进行比较,分析得出贻贝养殖生态系统能值产出率和可持续性均较高。

关 键 词:能值分析  贻贝养殖生态系统  可持续发展

Abstract:Emergy analysis method was applied to establish a related index system for analysis mussel aquaculture ecosystem in Dongji. In the study, indictors such as TR, ED, ELR, EYR, PEEI and ESI were used to evaluate the impacts of mussel aquaculture to the environment,as well as the sustainability of this aquacul-ture ecosystem. The results showed that the solar emergy conversion rate TR of mussel aquaculture ecosystem was 3.35E+09sej/g, the environmental load rate ELR was 0.45, the emergy output rate EYR was 3.22, the production efficiency of emergy input PEEI was 9.60E-10g/sej and emergy sustainable development index ESI was 7.16. Based on the above analysis and compared with the other four aquaculture systems, we found that mussel aquaculture ecosystem had high emergy output rate and emergy sustainable development index.
Keywords:emergy analysis  mussel aquaculture ecosystem  sustainable ability
