Abstract: The conflict between rapid urban growth and the maintenance of water landscape is gaining momentum in China. The shapes of the urban lakes have been deeply affected by the rapid urbanization in recent decades. This study analyzed the temporal-spatial change of East Lake as the largest urban lake in China using remote sensing images during 1990–2013. Then the STIRPAT model is employed to assess the impact of human activities as driving force on lake changes. The results indicated that the surface area of East Lake showed a slight decrease trend in the first decade and a sharply reduce trend from 2000 to 2013. The accelerated decline trend of landscape shape indexes showed that the shapes complexity of East Lake's water body was decreasing and human intervention was intensifying in the study area. The increasing population and urbanization are found to be the principal driving forces of recession of East Lake ecosystem. And we conclude the driving mechanism of morphological change of urban lake to better understand the reasons of the urban lake change. The conservation of urban lake should be emphasized due to its fragility during rapid urban expansion.
