Climate warming as the main feature of climate change has become current research focus, and the interaction between climate change and different types of ecosystems is widely concerned. Northeast China is one of the most sensitive areas o￡ climate change where the observation records and a variety of forecasting models show that it has experienced a significant climate warming period and the trend will be further enhanced. However, precipitations have not obvious trends or show alightly increase. Lake group in Songnen Plain is one of the highest density lake district in China. However, in the recent decades, its ecological environment has been continuously deteriorated due to several factors that climate change is the obvious one.In this paper, responses of Songnen Plain lakes to climate change are summarized from the following three characteristics:(1) lake area and lake water level; (2) lake water quality; and (3) lake ecological diversity. On the basis of above study, impact of future climate change on Songnen Plain lakes ami the lakes' evolution trend are estimated, Human activities' impact on the environmental evolution of the lakes is also discussed.
