摘　　要：通过分析SeaWiFS Chla与现场Chla的相关性，统计SeaWiFS遥感数据在福建近海的时间覆盖率，对SeaWiFS遥感数据在福建近海赤潮监测的适用性进行初步评估。结果表明，SeaWiFS Chla与现场Chla呈良好的线性关系，能够很好反映现场Chla的空间分布情况；4～6月SeaWiFS遥感数据量稀少，难以满足赤潮监测的要求；7～9月数据量显著增加，基本可以满足SeaWiFS对较开阔的福建近海进行赤潮监测。We studied the Correlation of SeaWiFS Chla and in situ Chla and discussed the time coverage fraction of SeaWiFS data in Fujian coastal waters to give a primary evaluation of SeaWiFS data on red tide monitoring in Fujian coastal waters. As a result, SeaWiFS Chla have a good correlation with in situ Chla, which can be very good to reflect the spatial distribution of in situ Chla. From April to June SeaWiFS data cannot satisfy the red tide monitoring for its data coverage on Fujian coastal waters. However, the time coverage fraction increase significantly from July to September, which can be used on red tide monitoring in open area of Fujian coastal waters.
