| 摘 要： | 针对2004年6月11日和2005年5月25日发生在长江口及邻近海域的赤潮,利用EOS/MODIS遥感数据进行监测研究。采用海表温度19°C及叶绿素a浓度6mg/m3经验数据作为阈值,结合多波段差值比值法对MODIS遥感图像中长江口及邻近海域的赤潮进行综合检验。研究结果表明,利用MODIS遥感数据探测赤潮是可行的,并建立了运用多波段差值比值法、海表温度及叶绿素a浓度的阈值综合判定法对赤潮灾害进行探测的方法。

| Abstract: | Aiming at the Red Tides occurred in the Yangtze Estuary and adjacent waters on June 11th,2004 and May 25th,2005,it was taken the experienced value of SST 19°C and Chl-a 6 mg/m3 as the threshold combined with multi-band ratio to detect Red tide occurred in the waters mentioned above.We came to the conclusion that using MODIS to detect Red Tide is feasible,the methods used with EOS/MODIS remote sense data by way of doing aforementioned for detecting the Red Tide have been build. |
