| Abstract: | In this paper,the Landsat 8 OLI_TIRS satellite remote sensing images of different periods in the past 24 years are used as data sources to study the water area of the East Lake in Wuhan.The dynamic changes of the water area of the East Lake in recent years are analyzed.The water area is extracted by the improved normalized difference water index(MNDWI),and the meteorological data and urban development data of the past years are combined.The results show that the change of water area of East Lake in recent years is closely related to the change of urban development and human utilization. |
