- Abstract:

Based on daily precipitation data at 22 basic meteorological stations in Shandong Province during the period from 1981 to 2017, the changes in distribution of precipitation in flooding season in Shandong Province were comprehensively analyzed using the concentration index(Q), and spatial-temporal distribution characteristics and changing trend of different grads precipitation were analyzed. The results indicated that the regions with smaller Q indexes were middle Shandong and south-east Shandong and the areas with the bigger Q indexes were northern coast of Shandong Peninsula and western Shandong; the Q indexes presented the decreasing trends in most regions of middle-west Shandong and increasing trends in coast regions of Shandong Peninsula; the total amount of precipitation and days precipitation in most regions presented the increasing trends; days of strong and extreme precipitation were more obvious and precipitation was more concentrated in coast regions of Shandong Peninsula.
