摘　　要：安庆市沿长江分布的湖泊的生态环境问题突出。遥感技术在大尺度水体监测方面具有优势和潜力。利用2013年至2021年的Landsat 8 OLI影像数据,反演安庆市沿长江分布的龙感湖、黄大湖、泊湖、武昌湖、菜子湖、破罡湖和石塘湖水体的色调角和水色指数(Forel-Ule index,FUI),分析7座湖泊水体的色调角和水色指数的分布特征及其变化趋势。研究结果表明,各季节安庆市沿长江分布的7座湖泊水体的营养状态处于中营养至中度富营养状态,水体的颜色为绿色、绿棕色渐变到棕绿色;武昌湖和泊湖水体的颜色相对较浅,龙感湖和黄大湖水体的颜色相对较深;水体浊度和水体中的叶绿素a含量是影响水体颜色的主要因素。There are many lakes along the Yangtze River in Anqing city,which are of great ecological and environmental values.With the development of social economy and the impact of human activities,the ecological environment issues stand out.Satellite remote sensing technology play important advantages and potential for large-scale water monitoring.In this study,7 lakes distributed along the Yangtze River in Anqing city were selected,which are Longgang Lake,Huangda Lake,Po Lake,Wuchang Lake,Caizi Lake,Pogang Lake and Shitang Lake.And Landsat 8 OLI data from 2013 to 2021 were used in the study.The distribution characteristics and change trends of hue angle and water color index retrieved from remote sensing data showed that the nutrient statuses of 7 lakes in different seasons were in moderate to moderate eutrophic states,and the colors of the water bodies were green with a green-brown gradient to brown-green.The colors of the water bodies of Wuchang Lake and Po Lake were relatively light,and the colors of the water bodies of Longguan Lake and Huangda Lake were relatively dark.The turbidity of the water bodies and the chlorophyll-a contents in the water bodies were the main factors affecting the colors of the water bodies.
