Eutrophication evaluation of three lakes and one reservoir using CCD images from the HJ-1 satellite
基于环境一号卫星多光谱影像数据的三湖一库富营养化状态评价

The Chinese domestic satellite HJ-1 was launched in 2008. Because of its 2-day temporal resolution,it has become a significant resource for environment and disaster monitoring. Based on the in situ measured data,which are spectral reflectance and water quality parameters in Lake Taihu,Lake Chaohu,Lake Dianchi and the Three Gorges Reservoir,eutrophication evaluation models were developed. The models were based on the band settings of the HI-1 CCD images,and were used to quantify the nutritional status of the...
