摘　　要：渤海是我国易发生赤潮的海域之一,近年来,赤潮灾害越来越频繁且呈现加重态势。天津市沿岸海域位于渤海湾,是渤海赤潮频繁出现的典型区域,监测渤海赤潮现象的出现、进展和消退对环境保护和生态安全至关重要。本文基于海洋一号D(HY-1D)遥感影像数据,比较分析了光谱响应法、波段比值法和赤潮指数法等3种方法。结果表明:基于海洋卫星数据L2A级产品的光谱响应法、波段比值法和赤潮指数法均可用于赤潮水体的遥感监测。The Bohai Sea is one of the China's most severely affected regions by red tide occurrences.In recent years,red tide disasters are becoming increasingly frequent and severe.The coastal waters of Tianjin,located in the Bohai Bay,represent a typical area of frequent red tide outbreaks in the Bohai Sea.So monitoring the emergence,progression,and dissipation of red tide phenomena becomes crucial for environmental protection and ecological security in this region.In this paper,based on the data of HY-1D remote sensing image,such methods as the spectral response,band ratio and red tide index were compared and analyzed.The results show that the spectral response method,the band ratio method and the red tide index method based on the L2A product of ocean satellite data can be used for the remote sensing monitoring of red tide water bodies.
