摘要：We assess the vulnerability of cropland to soil water erosion and the effectiveness of two soil conservation measures in Austria. Potential sediment yields are simulated with the RUSLE (Revised Universal Soil Loss Equation) methodology for five climate change scenarios until 2040 using the bio-physical process model EPIC (Environmental Policy Integrated Climate). Cropland has been assigned to five vulnerability classes according to OECD (2001). Potential changes in mean annual crop yields and gross margins have been calculated. The model results indicate increasing sediment yields with higher precipitation sums. Reduced tillage and cultivating winter cover crops have been identified as effective adaptation options though they generally result in lower crop yields and gross margins. However, the additional variable costs are over-compensated by current agri-environmental premiums
