Description :
This article discusses the driving forces impacting the reservoir wetland evolution in Beijing during 1984–2010. The results show that for the 1984-1988 period, average annual precipitation and entry water index were the major factors driving the increase in wetland area. From 1998 to 2004, as the impact of human activities intensified, the main driving factors were the number of residents, groundwater depth and urbanization rate, which caused the wetland shrinkage rapidly. During 2004–2010, reservoir wetland evolution was impacted by both natural and socio-economic factors, and the dominant driving factors were urbanization rate and precipitation respectively and caused the wetland total area growth slightly.
