【摘要】：温度是影响藻类生长繁殖的一个重要因素。本文针对2013年6月在黄海海域出现的大量浒苔和马尾藻事件,基于MODIS(Moderate-Resolution Imaging Spectroradiometer)卫星遥感数据,分析了此次事件中浒苔和马尾藻生消过程与海表面温度之间的关系。首先根据浒苔、马尾藻和水体的光谱特征曲线,本文利用大型浮游藻类指数(Macroalgae Index,MI)对浒苔和马尾藻进行了识别,并且对浒苔和马尾藻生消过程中的MI值和对应的海表面温度进行了分析,结果表明:在此次事件中,海水温度是影响浒苔和马尾藻生长繁殖的重要环境因子,浒苔和马尾藻处的海表面温度比周围水体的海表面温度高1~2℃,浒苔和马尾藻爆发的适宜温度范围为23~26℃。
[Abstract]:Temperature is an important factor affecting algae growth and reproduction. In this paper, based on MODIS(Moderate-Resolution Imaging Spectroradioradiometeral remote sensing data, a large number of events of Enteromorpha enteromorpha and Sargassum occurred in the sea area of Huang Hai in June 2013. The relationship between the growth and extinction process of Enteromorpha enteromorpha and Sargassum and sea surface temperature was analyzed. Firstly, according to the spectral characteristic curves of Enteromorpha enteromorpha, Sargassum sargassum and water body, In this paper, macrophytic algae index (Macroalgae Indexm MI) is used to identify Enteromorpha and Sargassum, and the MI value and sea surface temperature during the process of growth and extinction of Enteromorpha enteromorpha and Sargassum are analyzed. The results show that: in this event, Sea water temperature is an important environmental factor affecting the growth and reproduction of Enteromorpha margin and Sargassum. The sea surface temperature of Enteromorpha enteromorpha and Sargassum is 1 + 2 鈩，
