| 摘 要： | 通过获取的Modis和SeaWiFS遥感数据,包括2001、2002、2004、2005年东黄海秋季海表水温和叶绿素数据,运用分位数回归方法对环境数据和小黄鱼Larimichthys polyactis的单位捕捞努力量渔获量（CPUE）进行分析,得出小黄鱼最佳栖息地指数（HSI）模型。利用Surfer软件绘制小黄鱼不同年份秋季HSI的分布,得出32°N~33°N、122°30′~123°30′E海域范围内小黄鱼的HSI值较高（HSI〉0.5）,比较适合小黄鱼索饵栖息,而在30°N以南、125°E以东海域HSI指数值较低（HSI〈0.5）,不太适合其索饵栖息。 |

| Abstract: | In this paper,the distribution of sea surface temperature（SST） and chlorophyll concentration were obtained from Modis and SeaWiFS data in the East Sea and the Yellow Sea in 2001,2002,2004, and 2005. These environmental factors and catch per unit effort （CPUE） of small yellow croaker （Pseudosciaena polyactis） were estimated by quantity regression, and then the habitat suitability index （HSI） model was used to analyze the predicted data of small yellow croaker. The results showed that the distribution of feeding migration of small yellow croaker was found. The HSI maps of small yellow croaker were drawn by Surfer software, and showed that the HSI value in the region of 32°N- 33°N, 122° 30′ - 123°30′ E were higher than in other regions, so the region probably was the more suitable habitat of the feeding migration stock. However,HSI value in south of 30°N and east of 125°E were lower than in other regions, indicating that these regions were not suitable for feeding migration stock. |
