In this study, the inter-annual, intra-annual and regional variation rules of each element were obtained through analyzing precipitation, runoff and other elements of hy- drology and water resources in the Poyang Lake basin. Meanwhile, the Mann-Kendall (MK) me- thod was used to analyze the precipitation of the Poyang Lake basin and the significance level of variation trend of annual inflow in each station.
