中文摘要:
      基于2006—2015年9—11月西北太平洋(36°N~48°N和150°E~170°E)海域柔鱼(Ommastrephes bartarmii)生产捕捞数据并结合关键环境因子海表面温度(sea surface temperature,SST)和海表面高度距平(sea surface height anomaly,SSHA),构建各月单因子不同权重的综合栖息地指数模型(habitat suitability index model,HSI),按照模型性能筛选出每月最优模型并加以验证。此外,利用最优模型预测柔鱼栖息地适宜性程度,并比较厄尔尼诺和拉尼娜事件下柔鱼栖息地时空分布的差异性,评估柔鱼生境质量与资源丰度、渔场分布的关系。结果显示,9—11月各月最优HSI模型的单因子适宜性指数(suitability index,SI) SISST和SISSHA权重比例分别为9月0.9∶0.1、10月0.7∶0.3、11月0.8∶0.2,显然每月SST贡献率都是最高的,表明水温对柔鱼栖息地时空分布的影响最为关键。对比分析厄尔尼诺年份(2009和2015年)与拉尼娜年份(2007和2010年)柔鱼的生境质量、资源丰度和渔场纬度重心可知,相较厄尔尼诺事件,拉尼娜事件的发生有利于柔鱼的生存,促使其适宜生境范围扩大,产量提升。柔鱼偏好的水温向北移动驱使渔场位置同样北移。
英文摘要:
      According to the fisheries data of Ommastrephes bartarmii combined with the sea surface temperature (SST) and sea surface height anomaly (SSHA) data obtained from 36°N to 48°N, 150°E to 170°E in northwest Pacific Ocean from September to November, 2006-2015, monthly habitat suitability index models (HSI) were established based on key marine environmental factors of different weighting scenarios, and monthly optimal model was selected and verified according to the model performance.Furthermore, the optimal HSI models predicted the habitat suitability, and the impacts of El Niño and La Niña on habitat suitability of O.bartramii are also compared, and the relationship between habitat quality and abundance, distribution are evaluated. The results showed that the weighting proportion of SISSTand SISSHA of the monthly optimal HSI models from September to November were as follows:0.9:0.1 in September, 0.7:0.3 in October, and 0.8:0.2 in November. Obviously, the contribution of SST was the highest, indicating that SST was the most important factor for spatial and temporal distribution of habitat. Moreover, comparing the impacts of El Niño years (2009 and 2015) and La Niña years (2007 and 2010) on habitat suitability,stocks abundance and latitudinal gravity center of fishing ground of O.bartramii, it is found that the La Niña events were more beneficial to the survival of O.bartramii than the El Niño events, and the suitable habitat area also increased the catch. Suitable SST moved north, resulting in a northward shift of fishing ground location as well.
