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℃。
Temperature is an important factor which influences the growth and propagation of algae.This study takes an example of a large number of Enteromorpha and Sargassum in the Yellow Sea in June,2013.According to the spectral characteristic curves of Enteromorpha,Sargassum and water column,MI（Macroalgae Index）is established and tested based on MODIS（Moderate-Resolution Imaging Spectroradiometer）satellite remote sensing data.An analysis between the MI of the processes of Enteromorpha and Sargassum and sea surface temperature shows：In this event,water temperature is a key environmental factor influenced the growth and propagation of Enteromorpha and Sargassum,and sea surface temperature will also increase because of a large number of Enteromorpha and Sargassum existing in sea surface.Meanwhile,23～26℃is the necessary condition of the breaking out of Enteromorpha and Sargassum.
