Abstract:: Based on the daily precipitation data of 18 meteorological stations in Shandong Province from 1981 to 2010, Inverse Distance Weighted (IDW), Mann-Kendall nonparametric test method, Pearson correlation coefficient and wavelet analysis were used to comprehensive study the temporal and spatial distribution characteristics of precipitation in recent 30 years in Shandong. The results show that, with respect to spatial distribution, Taishan, Rizhao and Shidao region are the rainy areas, the annual rainfall is 740 mm or more; Shenxian, Huimin County and Dongying and other places are the less rainy areas, the annual rainfall in the 500~550 mm or so. Precipitation is greater in the coastal areas than that in the inland, it is greater in mountain than the plain. In the time distribution, the annual precipitation showed the upward trend, and the increase of precipitation in coastal areas was generally greater than that in inland areas, of which the largest increase was observed in Weihai, up to 9.71 mm/year. With respect to the seasons, the spring and summer are consistent with the whole year, the precipitation presented the rising trend, and the precipitation in some parts in the autumn and winter showed the downward trend, which was most obvious in autumn, a large negative value was found in the southeast coast and southern Shandong. The mutation test showed that there was the sudden increase in annual precipitation in Shandong in 1997. The analysis showed that the precipitation change in Shandong had the similar oscillation cycle with the southern oscillation and east Asian summer monsoon, and there was certain response in space, but there was an obvious regional difference.
