中文摘要：

针对海表温度锋的模糊边缘特点,首先利用詹森香农散度,借助4个方向,5×5大小的结构元素,对2009年、2010年中国东部海域海表温度（SST）卫星遥感数据进行处理,得到锋面的可能发生区,然后引入模糊蕴涵算子,对图像进行模糊变换,最后使用边缘检测方法提取锋面可能发生区内存在的温度锋。检测结果表明：在中国东部海域存在3个主要的锋面,各锋面的空间分布和强度均存在明显的季节变化,大致呈现冬春强,夏秋弱的趋势。

英文摘要：

This study applies an edge detection method to satellite sea surface temperature（SST） images in order to distinguish SST fronts which occur frequently in China＇s east coast in the year of 2009 and 2010.Because of the feature of the fuzzy front edge,we use Jensen-Shannon divergence to detect the possible frontal areas with the help of the four direction operators sized in 5×5.Then we introduce the fuzzy implication operator to detect the sea surface temperature fronts in the area.Experimental results indicate that there are three major fronts,and the spatial distribution and magnitude of the fronts are seasonal;in general,they are strong in winter and spring,while weak in summer and autumn.
