摘要
通过系统性的常规水质采样分析与水面光谱测量外场同步试验,建立了由FY-1C多通道扫描辐射计、Landsat卫星TM和Seastar卫星SeaWiFS等在轨卫星多通道遥感器以及一组设想的遥感通道遥感反演叶绿素a浓度和总悬浮物浓度的优化通道组合模型,提出了一种利用水面上标准反射板的反射光谱和遥感图像本身确定大气透过率和反射率从而实现大气校正的水质指标卫星遥感反演方法.所建立的模型和方法被用于遥感解译我国典型富营养化湖泊太湖和滇池从80至90年代的富营养化程度及其分布状况随年份的变化.本项研究为进一步开展湖泊水质业务化卫星监测打下了基础.
Abstract
By field experiment in water sampling for chemical analysis and synchronous measurement of reflected light spectrum of water, the optimal channel combination models were obtained to retrieve chlorophyll-a concentration and suspended sediment concentration from remote sensing data of FY-1C multi-channel scanning radiometer, Landsat-5 TM, SeaWiFS of Seasat and a supposed set of remote sensing channels. A method retrieving water quality parameters by satellite remote sensing was suggested, in which the atmospheric transmittance and reflectance were determined by the reflected light spectrum of standard reflecting board on water and satellite remote sensing images themselves for the atmospheric calibration. The models and methods were used to retrieve the eutrophic degree, its space distribution and its change with year of Tai lake and Dianchi lake, which are typical eutrophic lakes of china, in 1980s and 1990s. The results of this study could be as the bases for operational satellite remote sensing of water qual
