Abstract
湖泊水体散射特性的研究对湖泊水色要素遥感反演模型的发展具有重要的意义.本研究利用AC-S和ECO-BB9实测了巢湖水体的散射系数和后向散射系数,在分析光谱变化特性的基础上,构建了悬浮颗粒物散射系数和后向散射系数的幂函数光谱模型,获得的光谱指数分别为0.86和3.24.研究发现悬浮颗粒物散射系数与TSM和ISM都存在较好的线性函数关系,进而提出水体中总悬浮颗粒物的比散射系数为0.6364(10-3m2·mg-1),无机悬浮颗粒物的比散射系数为0.9108(10-3m2·mg-1).同时,分析了悬浮颗粒物后向散射率和折射指数的变化,其变化范围分别为0.003～0.026和1.02～1.06.
