土壤侵蚀是世界上最严重的环境灾害之一。了解气候变暖背景下局地和流域尺度降雨侵蚀力（RE）和侵蚀力密度（艾德）的变化及其影响因素是土壤侵蚀防治和土壤流失风险评价的重要前提。分析了1960-2012年赣江流域RE和艾德的时空变化特征和变化趋势，并对气候变化的影响进行了分析和讨论。结果表明，小流域的RE和艾德具有较大的月变化和年际变化。在整个研究期间，两者均呈长期增长趋势。结果表明：6月、流域东部和东北部的RE和艾德最高，表明6月是该地区土壤侵蚀最易发生的月份，赣江下游是土壤侵蚀最危险的区域。最后，东亚夏季风和气候变化与RE和ED的变化高度相关。
Soil erosion is one of the most critical environmental hazards in the world. Understanding the changes in rainfall erosivity (RE) and erosivity density (ED), as well as their affecting factors, at local and catchment scales in the context of climate warming is an important prerequisite of soil erosion prevention and soil loss risk assessment. The present study identified the variability and trends of RE and ED in terms of both time and space in the Ganjiang River catchment over the period of 1960–2012, and also analyzed and discussed the impact of climate change. The results show that RE and ED in the catchment had great monthly variations and high year-to-year variability. Both presented long-term increasing trends over the entire study period. The highest RE and ED were observed in June and in the eastern and northeast parts of the catchment, which indicated that June was the most susceptible month for soil erosion in this area and the lower reaches of the Ganjiang River was the riskiest area for soil erosion. Finally, the East Asian summer monsoon and climate change were highly correlated with changes in RE and ED.
