摘要
利用MODIS获取的2002年7月—2007年12月卫星数据反演中国东海海域的海表温度(SST)和叶绿素a浓度信息,对东海海域的SST和叶绿素a浓度分布规律进行了分析。结果表明:东海海域的SST和叶绿素a浓度的分布具有明显的分区和季节变化特征。在年际间,不同海区的SST和叶绿素a浓度均呈周期性变化趋势。在空间上,SST呈现出由近岸向外海递增的趋势,南北温差大;叶绿素a浓度则呈现出由近岸向外海递减的分布趋势。东海叶绿素a浓度的分布与SST、河口径流、季节等因素有关。作者从宏观上分析了东海长时间序列的SST和叶绿素a浓度的变化特征,可为东海海洋初级生产力和海洋生态环境研究提供参考。
In this paper, the characteristics of distribution and variation in sea surface temperature（SST） and chlorophyll - a（ Chl - a） concentration was retrieved in East China Sea by MODIS from July of 2002 to December of 2007. The distribution of SST and Chl - a in East China Sea was found to be characterized by regional and seasonal changes. Annually, periodical changes in SST and Chl - a concentration were found, and spatially, the SST was found to increase from coastal sea to off sea, and to have great fluctuation in temperature between north and south. In the chlorophyll - a concentration, however, there was a decrease trend from coastal sea to off sea, indicating that this distribution of chl- a in the East China Sea was involved in the SST, river current, and various seasons. The long - term variations in SST and chlorophyll - a concentration were discussed, and had given new insight into oceanic primary production and marine ecological environmental research.
