中文摘要：
应用SeaWiFS遥感数据,采用最新的基于固有光学特性的半分析算法进行台湾海峡真光层反演,与卫星过境时间±2小时内实测的数据比对的结果,平均相对误差为16.7%,均方根误差为0.077 81,遥感反演与实测数据之间相关系数达到0.87.相对于叶绿素反演算法（平均相对误差38.0%,均方根误差0.152 4,相关系数0.56）,有较高的反演准确性.说明该算法不仅适用于Gulf of Mexico、Monterey Bay和Arabian Sea,也适用于台湾海峡.
英文摘要：
This article employs SeaWiFS data over the Taiwan Strait to evaluate a semi-analytical algorithm for euphotic zone depth, This algorithm is based on water＇s inherent optical properties（IOP）, which can be near-analytically calculated from spectral remote-sensing reflectance（provided by SeaWiFS）. Compared with in situ Zeu（±2 h）,average error is 16. 7 % ,root mean square is 0. 0778 and correlation coefficient is 0. 87. It has higher accuracy compared to chlorophyll-a approach（average error is 38. 0%, root mean square is 0, 1524,correlation coefficient is 0.56）. It is found that the new algorithm not only worked well with waters of the Gulf of Mexico,Monterey Bay and Arabian Sea,but also worked well with waters of the Taiwan Strait.
