Using Chinese squid fishing production data during the main fishing season from 1999 to 2004 in the waters of 150—165°E, the present study combines the sea surface temperature with the horizontal gradient and the percentage of fishing times and daily catch as the suitability index. Using arithmetic mean model and geometric mean model, the integrated habitat suitability index is established based on SST and GSST .

中文摘要：根据 1999—2004 年8—10 月主渔汛期间我国鱿钓船在150—165°E 海域的鱿钓生产数据，结合其表温及表温梯度，分别将作业次数百分比和单位渔船日产量作为适应性指数，利用算术平均法和联乘法分别建立基于表温因子的综合栖息地指数模型。
