Spatial and Temporal Variability of Annual Precipitation during 1958-2007 in Loess Plateau, China

摘要：

The non-parametric Mann-Kendall method and Sliding rtest were applied in this study to analyze the spatial and temporal patterns of trends of the precipitation in the Loess Plateau from 1958 to 2007. The main trends of the precipitation in this region is downward, only four upward time series have not reach the significant level. Most of the abrupt changes happened in northeast of Loess Plateau during 1980s and 1990s.
