将能值分析方法引入渔业生态系统的可持续发展研究中,对处于结构调整期的大连市渔业系统进行了定量分析和评价.结果表明,2005年大连市渔业生态系统能值投入率为1.23,净能值产出率为1.57,环境负载率为1.65,环境压力相对较小,渔业生态系统运行状况良好.2001～2005年间,大连渔业系统的环境负载率呈下降趋势,可持续发展指数保持在1.00左右,在保证产量和产值增长的同时有效的降低了环境负荷.大连市应继续推进渔业结构和布局调整,加大高科技含量能值的投入,同时注重自身优势资源的高效利用,促进渔业生态系统的可持续发展.

This paper deals with the energy analysis on the development sustainability of the fishery ecosystem. The quantitative analysis and the evaluation are applied for the improving fishery system of Dalian. The results showed that the energy investment ration, the net energy yield ration, and the environment loading ratio was 1.23, 1.57 and 1.65, respectively in 2005. The environment loading assumed a tendency to descend, and sustainability index based on energy analysis was around 1.00 steadily from 2001 to 2005. That means the fishery ecosystem in Dalian was up to a higher level and the environmental pressure was not great correspondingly. The city should pay more attention to adjust the structure of the fishery ecosystem. In order to promote the sustainable development of this system, the investment proportion of advanced technology energy should be enhanced gradually, and the effective application of competitive resource in this system should be strengthened at the same time.
