Abstract


Influenced by global warming and other factors, the climatic characteristics of the Dianchi Lake (in Yunnan Province) are obviously different from those in northern China. Based on the data of rainfall and runoff from 1956 to 2012, this paper analyzed the variation characteristics of precipitation and runoff in Dianchi Lake Basin. The results showed that the precipitation and runoff showed a decreasing trend. There are several time scales in the runoff variation, which has the first main cycle of 15a.
