摘要

为优化辽宁省海水养殖业的产业结构,促进海洋生态文明建设和海洋经济高质量发展,文章在分析辽宁省围海养殖现状的基础上,从生态效益和经济效益2个方面论证围海养殖的用海效益,并对退出机制提出建议。研究结果表明:辽宁省围海养殖规模较大,已对近岸海域生态环境造成不良影响;通过建立投入产出指标体系并计算投入产出比,围海养殖的生态效益较低;以围海养殖海参为例,通过分析其单位产量、单位产值和养殖面积,综合考虑产业贡献和养殖方式对比的情况,围海养殖的经济效益降低;由于用海效益总体较低,围海养殖的逐步退出势在必行,应采取清退或清除的方式,针对不同类别科学建立退出机制。
        In order to optimize the industrial structure of mariculture industry in Liaoning province and promote the construction of marine ecological civilization and the high-quality development of marine economy.Based on the results which the analysis of the present situation of the cofferdam mariculture in Liaoning province,the paper demonstrated the benefits of the cofferdam mariculture from two aspects of ecological and economic benefits,and put forward some suggestions on the withdrawal mechanism.The results showed that the scale of the cofferdam mariculture in Liaoning province was large,which had caused adverse effects on the ecological environment of offshore waters.The ecological benefits of the cofferdam mariculture were low by establishing inputoutput index system and calculating input-output ratio.Taking the sea cucumber of cofferdam mariculture as an example,by analyzing its per unit yield,per unit output value and cultivation area,the situation of industrial contribution and comparison of cultivation modes was comprehensively considered.In addition,the economic benefits of the cofferdam mariculture were reduced,and the gradual withdrawal of the cofferdam mariculture was imperative because of the overall low efficiency of the cofferdam mariculture.The withdrawal mechanism should be established scientifically according to different categories by means of clearance or removal.
