| 摘 要： | 为了使养殖场因有害性赤潮而受到的损失最小，最好的方法是在赤潮扩散之前探测出赤潮的发生。利用人造卫星资料和GIS技术，采用海色算法和空间分析技术进行赤潮的探测。本文按日为计量单位，利用HABAS程序表示出从1995年至2004年发生在韩国沿岸的有害性赤潮的空间分布、密度和生物种。空间分析结论是通过比较卫星资料和现场观测得出的。通过分类有害性赤潮地区分布，来完成对有害性赤潮初期发生地区的分析。

| Abstract: | The outbreaks of Harmful Algal Blooms(HABs) in the South Korea coastal waters became frequent and widespread since the 1990s. They were generally observed from late spring to autumn, with peak in the late summer season (from July to September). In order to decrease the economical loss of aquaculture caused by HAB, the most important thing is how we can early detect it before the blooming. Satellite remotely sensed data and GIS technique is available for HAB monitoring system, which has ocean color algorithm and spatial analysis methods. In this study, HABAS (Harmful Algal Bloom Analysis System) program showed the dispersion area, species and density of daily algal bloom from 1995 to 2004 in Korean waters. The spatial analysis were carried out with satellite remotely sensed data and field survey reference data. The initial stage area of HAB outbreaks classified with HAB distribution area. |
