Abstract
In order to explore the change of 50 years’ rainfall trend and abrupt change in WeiHe Basin, we using the annual rainfall data of 21 important control stations in WeiHe basin from 1960 to 2012 to analyze the changes in the time rainfall and the change trend of the annual rainfall anomaly, and using Kendall - Mann method to test the trend of rainfall in WeiHe Basin. It shows that rainfall rate keeps decreasing during the last 50 years, and the change rate of upstream is generally greater than the midstream and downstream. For mutation years, it occurs in 1970s in downstream, in1970s and 1980s in midstream and in 1990s and after 2000 in upstream. It shows that the change of rainfall in different regions have different performance. From the tendency analysis, we can predict that the whole WeiHe basin will keep a decreasing trend of annual rainfall in the future.
