摘　　要：以巢湖为实验区,以气象卫星 FY-1C/CAVHRR数据为信息源,通过遥感监测值与(准)同步湖区实地采样叶绿素α(chl-α)含量的对比分析,建立基于 FY-1C/CAVHRR数据的叶绿素α含量遥感估算模型。研究表明,FY-1C气象卫星可用于内陆大面积湖泊湖面叶绿素含量的遥感监测,在动态监测方面有明显优势,可作为现有湖泊水质采样现测的补充手段。By the use of the meteorological satellite FY-1C/CAVHRR data .estimated are the concentrations of chlorophyll-a in Chaohu Lake. A remote sensing estimating model is proposed by analyzing the correlation of the FY-1C/CAVHRR channel data for watercolor monitoring and synchronal field survey for chlorophyll-a concentrations. The result indicates that meteorological satellite FY-1C can be used to monitor concentrations of chlorophyll-a in large lakes as a kind of important assistant means of routine water quality sampling survey with its advantages of time and spatial resolution.
