Abstract：The chlorophyll-a concentration, suspended solids concentration, transparency and eutrophication index for the Taihu Lake were obtained by using GF-1 satellite wide field of view (WFV) camera and HJ-1A satellite CCD camera data with the purpose of evaluating the GF-1 satellite's application capability in environmental monitoring. The results show that the WFV camera data, consistent with the HJ-1A inversion results, could be used to monitor the distribution of the water quality parameters including chlorophyll-a concentration, suspended solids concentration, transparency and eutrophication index. It was shown that the algal blooming areas were found in the northwest of the Taihu Lake, the chlorophyll-a concentration was the highest near the algal blooming area, and the average of chlorophyll-a concentration in the whole lake was 62.46 mg·m-3. The suspended solids concentration was higher near the Zhusan Valley and the west coast area and decreased in the NW-SE direction, with the whole average value being 26.07mg·L-1. The transparency decreased in the NW-SE direction in contrast to the distribution of suspended solids concentration, with the whole average value being 22.1 cm. The eutrophication index decreased southeastward, being the same as the distribution of chlorophyll-a concentration, with the whole average value being 69.62. These results are consistent with the results of the routine surveying.
