2008年夏天, 浒苔在黄海、 东海海域第一次大规模爆发, 成为自然灾害, 严重威胁了第29届青岛奥帆赛的正常举办。 利用卫星、 航空、 船舶等不同平台的遥感方式对浒苔灾害进行实时、 连续、 动态的立体监测。 首先介绍了立体监测系统的构成; 然后在通过对浒苔、 海水灾害现场光谱测量的基础上分析浒苔光谱特征, 并结合多平台、 多传感器、 多光谱遥感数据的特点, 建立了浒苔信息提取模型; 最后对不同平台的遥感监测结果进行了比对, 结合时间序列数据, 分析了浒苔灾害演变趋势; 通过第29届奥帆赛区及周边海域应急监测的应用, 证明该立体监测系统方案的可行性。

In the summer 2008, Enteromorpha Prolifra broke out in Yellow Sea and East Sea on a large scale for the first time, and became a marine disaster. The authors constructed a stereoscopic monitoring system which monitored the disaster continuously, dynamically and in real time. The present paper introduced the construction of the stereoscopic monitoring system; through analyzing the spectral characteristics of Enteromorpha Prolifra and ocean water which were acquired in a field experiment, confirmed Enteromorpha Prolifra retrieval models based on multi-platform multi-sensor and multi-spectral remote sensing data, contrasted the different scale monitoring results, and analyzed the evolvement rules with time-series analysis. This system was applied to the Enteromorpha Prolifra emergency monitoring in the 29th Olympic sailing area. It was proved feasible and valuable for the Olympic safeguard.
