| 摘要: |
| 赤潮是海洋中一种复杂的生态异常现象。赤潮的爆发、不仅严重影响近海景观,破坏水产养殖,危害人体健康,还对海洋生态平衡造成破坏,给人类造成惨重经济损失。近年来,在我国的赤潮观测记录中,赤潮的年发生次数逐渐增加,且面积不断增大,因此,对赤潮的发生发展机理及预测治理研究是科学家刻不容缓的研究课题。
赤潮发生时,赤潮生物大量聚集,使水体颜色发生明显变化,进而赤潮水体的光谱特征发生变化,且存在差异,使利用水色遥感监测赤潮成为可能,还可以用来区分赤潮种类的不同。水体光谱的变化特性(包括吸收与散射特性)是水色赤潮遥感监测的基础,是水色遥感生物光学算法开发的重要组成部分。因此对赤潮水体进行光谱吸收特性的分析研究对于发展研究海区的水色遥感生物光学算法及赤潮遥感监测方法都有重要意义。 |

| Abstract: |
| Red tides are abnomal ecolog ical Phenamena which bring lots of damage in China every year Researh on detecting red tides is necessary, W ater color will change abnornally while red tides bloom out i e the absorption and scattering characteristics of waters will appear different With these varieties algorithms can be deve loped to retrieve water constituents from spectral reflectance Furthemore red tides detection mehods can be applied with retrieval chlorphyll concentrations. |
