| 摘 要： | 本文采用灰色关联分析方法对十年间海水养殖产量与13个相关因子的关联度进行评价,计算每个因子与海水养殖产量的灰色关联系数和灰色关联度,建立两两比较判断矩阵确定各因素对海水养殖产量的影响度。分析结果表明海水养殖产量的主控因子为：海水加工产品数量、水产品加工产值、海水养殖产值、水产苗种产值、渔民人均纯收入和海水养殖面积,影响度分别为：18.10%、16.69%、13.74%、13.65%、8.96%和8.67%,总影响度达79.81%。该结果能够较客观地反映影响我国海水养殖产量的主要因子,可将其作为制定海水养殖可持续发展政策和建议的依据。

| Abstract: | To analyze the relationship between mariculture production and related factors in China,grey relational analysis was used to evaluate the grey relational degree of mariculture production and thirteen impact factors in ten years（ 2003- 2012）. The grey relational coefficient and degree between each factor and mariculture production were estimated and a paired comparison matrix was constructed to quantitatively analyze the impact of each factor on mariculture production. Results of analysis showed that main factors affecting mariculture production included the number of marine processed products,output value of aquatic processed product,output value of mariculture,output value of aquatic fingerlings,piscatorial per capita net income and mariculture areas,whose affective degree were 18. 10%,16. 69%,13. 74%,13. 65%,8. 96%and 8. 67%,respectively,and the total affective degree reached 79. 81%. The analyzed results objectively indicated the main factors affecting mariculture production in China. These factors can be used as important references to formulate policies for sustainable development and recommendations. |
