Abstract: Rainfall is not only one of the most important drivers for soil erosion, but also the key factor for geological disasters such as landslide and mudslide. Furthermore, not only high intensity rainfall in short duration may lead to soil erosion, but also low intensity rainfall in long duration would increase the risk for geological disasters. Therefore, it is important to assess the features of rainfall amount and rainfall days for regional environment security. In this study, the temporal and spatial characteristics of rainfall amounts and rainfall days with different rainfall levels were analyzed by using linear trend method, Mann-Kendall test and R/ S method. This analysis was based on daily rainfall data collected from 17 meteorological stations in Fujian from 1960 to 2011. Mann-Kendall test is a non-parametric statistical method which has been widely used in the past. We used this method to analyze and test the trend of rainfall from 1960 to 2011. R/ S method was used to determine the trend of rainfall in the future. The Hurst values derived from R/ S method will specifically indicate the future trends for different rainfall levels. The results showed that the annual rainfall amounts increased while the rainfall days decreased significantly in the time series of 1960—2011. Both of them decreased spatially from northwestern to southeastern Fujian. The rainfall amounts and rainfall days of light rain and moderate rain for all seasons (spring, summer, autumn and winter) were decreased, while the rainfall amounts and rainfall days for heavy rain and rainstorm were increased for all seasons. The spatial variations of different rainfall levels for different seasons were significant. The central Fujian (Pingnan-Jiuxianshan) had the largest average annual rainfall amount for light rain. The southeast coastal area was always the high value region for heavy rain. The central Fujian had less rainstorms in winter than that in the northern and southern Fujian. The Hurst values showed that the rainfall amounts and rainfall days of heavy rain and rainstorm in spring, summer and winter would keep increasing in the future, but the rainfall amounts and rainfall days of light rain and moderate rain showed the reverse trend. It indicated that the enhanced frequency of extreme rainfall and periodic drought. Although the rainfall amounts and rainfall days showed significant fluctuation in time series and large difference at spatial level, the rainfall intensity would increase in the long term trend.
