Abstract: The climate in mid-latitude zone of the Northern Hemisphere has shown an tendency to get warm and dry since the beginning of this century. Due to such climatic change, most inland lakes fed mainly by precipitation have the change tendency of water level fall, and area shrinkage; only few lakes fed by glaciers have the tendency of expansion. By means of analysing the influence of precipitation and air temperatute change on lakes, it is found that the precipitation has a positive effect, namely, precipitation change is positively correlated with lake water level variation; while air temperatute has a negative effect. In addition, most lakes are sensitive to precipitation. And most lakes are in a state of the deficit of lake water volume for a long time, which is the reason to cause lake water level fall. The analysis of the relationsip between the lake basin shape and the response of lakes to climatic change shows that the lakes with shallow basins are sensitive to climatic change.
