| 1 | 利用卫星数据估算波罗的海的透明度和透光层深度显示文摘波罗的海水体透明度的长期变化趋势已按富营养化的观点加以解释。可以通过遥感数据估算得到光谱衰减系数K_d(490)。由于漫衰减系数与透明度之间存在着经验和理论关系,因此,利用遥感数据估算海水营养状态是可能的。本文研究了遥感和水下实测K_d(490)与分别于1999年在东波罗的海本体海区和2001年、2002年在西波罗的海本体海区/希默海区(Himmerfjrden)专门海上观测中获得的透明度之间的关系。利用水下测量值通过回归分析方法建立波罗的海PAR与光谱衰减系数间的关系。分析表明,在调查海区,K_d(490)约为K_d(PAR)的1.48倍。该关系用于定义透光层深度与遥感光学深度K_d(490)^(-1)间的关系。结果表明,透光层深度约是K_d(490)^(-1)的6.8倍。K_d(PAR)与透明度的回归分析结果证实了已有的研究结果,即K_d(PAR)为透明度倒数的1.7倍。再者,透明度与K_d(490)之间的水体成分反演算法用于模拟制作由SeaWiFS K_d(490)获得的波罗的海透明度分布图。该分布图通过海上实测数据加以验证,对卫星遥感获得的K_d(490)与实测K_d(490)做了对比,并讨论了产生误差的原因。 | Susanne Kratzer Bertil Hkansson Charlotte Sahlin 李四海 | 2003 | AMBIO-人类环境杂志2003，32，8： | 8 |
