| 摘 要： | 海表水温(SST)通常是表征鱼类栖息地分布的主要指标。本文根据1999—2007年我国大型灯光围网的鲐鱼生产统计数据,结合海洋遥感获得的SST,分析了渔汛期间鲐鱼栖息地的适宜SST范围,探讨了SST变动情况下鲐鱼栖息地的变化趋势。研究结果表明,东、黄海鲐鱼7—12月的适宜SST范围为15~30℃。根据政府气候变化专门委员会(IPCC)第四份评估报告,本文拟定4种SST上升的情况,即(1)每月平均SST+0.5℃;(2)每月平均SST+1℃;(3)每月平均SST+2℃;(4)每月平均SST+4℃。结果显示,东、黄海鲐鱼的潜在栖息有明显向北移动的趋势,并且栖息地面积逐渐减小。研究认为,全球气候变化引起的SST上升,可能会对近海鲐鱼栖息地造成严重的影响。

| Abstract: | Sea surface temperature (SST) is an important indicator representing fish habitat. According to Scomber japonicus fishery-dependent data of large lighting-purse seine, combining with SST by remote sensing, the suitable range of SST of Scomber japonicas during the fishing seasons are analyzed and the changing tendency of the Scomber japonicas habitat caused by variation of water temperature are also discussed. The results proved that suitable range of SST of Scomber japonicas in the East China Sea and Yellow Sea is 15-30℃. This study based on global climate simulations under several emission scenarios (A1FI, A1B, A1T, A2, B1, and B2) from the AR4 of the IPCC to examine the impact on potential habitats of Scomber japonicas for the next 100 years. So we simulate four kinds of water temperatures rise by gradient : (1) monthly average SST increase of 0.5℃;(2) monthly average SST increase of 1℃; (3) monthly average SST increase of 2℃;(4) monthly average SST increase of 4℃. The results indicated that the habitat of Scomber japonicas had a obvious northwards shifting tendency, and the area of habitat would decreased gradually. It is concluded that the rising SST caused by the global climate change would have a seriously effect on the habitat of Scomber japonicas. These results can make us understand the spatial distribution of Scomber japonicas influenced by SST in fishery management and fishery forecasting, which also provide the guide for the prediction of the Scomber japonicus potential habitat in the East China Sea and Yellow Sea. |
