Based on the monthly precipitation observation data of 17 hydrological representative stations in Shandong Province from 1956 to 2016, Moving-average method, Mann-Kendall test method, precipitation concentration degree and concentration period were used to comprehensively study the distribution characteristics of precipitation in Shandong. The results show that in terms of inter-annual changes, the annual precipitation in Shandong province shows a declining trend, and the precipitation in coastal areas is generally larger than that in inland areas. Judging from the annual distribution, the precipitation in Shandong during the flood season shows a downward trend, and the non-flood season precipitation shows an upward trend. From 1956 to 2016, the precipitation concentration degree and the precipitation concentration period in Shandong Province showed a weak decline.
