摘要：
There is evidence that, between hydrological years 1931/2 and 1990/1, rainfall changed in the Algarve. There was an annual rainfall increase (+9%) and a 7% increase in rainfall during the rainy period (October to February). Both trends were statistically confirmed by parametric and nonparametric procedures. Rainfall erosivity and land degradation are related to rainfall regime. The Algarve's rainfall erosivity increase (+17%) was more pronounced than annual and seasonal rainfall changes.
