Abstract

Fuxian Lake located in the middle of Yunnan Province is second deepest lake in china. The water level of Fuxian Lake descends and its water area reduces in recent years owing to the climate changing. Therefore, it is crucial for rational utilization of lake resources to study the change trend of Fuxian Lake’s area. Landsat images from 1974 to 2014 were used to monitor Fuxian Lake’s area change. Monitoring results show that there are four apparent features of Fuxian Lake’s area: (1) Years in which Fuxian Lake’s area are larger are concentrated in 2006 to 2009. (2) From 1974 to 1990, Fuxian Lake’s area change has a trend of decrease. (3) From 1990 to 2005, Fuxian Lake’s area change shows a rise trend on the whole. (4) From 2005 to 2014, there is an obvious decrease trend of Fuxian Lake’s area change.
