The monthly precipitation data from 14 stations were used to research the precipitation variation in Poyang lake basin during 1957–2012. The Mann–Kendall method was applied to analysis precipitation trends. There are two main periods of 1964~1975 and 1986~1999 with increasing annual precipitations for this basin. There is a highest coefficient of variation of the annual precipitation in the north mountain area of the basin. There are significant increasing trends in annual precipitation for Lushan station and Zhangshu station which located in the north. Six stations in the north had the significant upward trend in summer and eleven stations had the significant upward trend in winter. It can be determined that the Poyang lake basin has become wetter in winter over the period 1957-2012.
