%X Forel-Ule (FUI)指数可以反映湖泊水色变化，从而得知水体水质状况。本文基于FUI指数，利用Landsat影像数据，分析了呼伦湖1986~2023年水色时空变化特征，并探究了其影响因素。结果表明：呼伦湖FUI指数整体上呈逐步升高的趋势，且在2001年前后分别具有缓慢降低和波浪式升高的特征。空间上西部FUI值较低，而东部较高。此外，气温和降水与呼伦湖FUI指数月变化呈负相关关系。<br />
The Forel Ule (FUI) index can reflect changes in lake water color and thus determine the water quality status of the water body. Based on the FUI index and Landsat image data, this paper analyzes the spatial-temporal change characteristics of water color in Hulun Lake from 1986 to 2023, and explores its changing factors. The results show that the FUI index of Hulun Lake shows a trend of gradual increase on the whole, and has the characteristics of slow decrease and wave-like increase before and after 2001. The spatial FUI index is lower in the west and higher in the east. In addition, temperature and precipitation are negatively correlated with monthly changes of Hulun Lake FUI index.
