摘要
基于历年现场船舶、飞机、定点监测和陆岸监测的优势,获取了浒苔和马尾藻在水中的形态特征及光谱信息,绘制了光谱曲线;基于业务工作中常用的MODIS数据,采用真彩色法和马尾藻比值法开展业务化应用,并与现场监测结果进行对比分析;分析结果表明:采用真彩色法和马尾藻比值法结合,能够快速、有效区分浒苔和马尾藻,满足业务监测工作的需求。
The morphological characteristic and spectral information of Enteromorpha and Sargassum in water are obtained,and spectral curves are plotted by taking advantages of field ships,aircraft,fixed-point monitoring and land-based monitoring over the years.True color method and ratio method are used to conduct operational application based on the common-used MODIS datasets,and comparison is made between the application results and field monitoring.It is found that the combination of true color method and ratio method can quickly and effectively distinguish Enteromorpha from Sargassum,which meet the needs of operational monitoring.
