报告摘要:Rainfall erosivity and hillslope erosion are being significantly affected by frequent extreme weather events and ongoing climate change. Projected warmer climate in Australia will comprehensively change the erosion rates through more intensive storm events, more severe and frequent wildfire and less snowmelt. Moreover, Australian rainfall is dominated by high seasonal and interannual variability for current and also future climate, which was believed to increase the hillslope erosion and accelerate the land degradation through the high variation of rainfall erosivity. To estimate the near real-time rainfall erosivity and erosion change, it is essential to link extreme weather events with hillslope erosion model in response to the needs of effective ecosystem and environment management. The output of this research will assist with government decision-making of soil and land management, and more importantly, in adapting to changing climate and extreme weather.
