摘要
以全球变暖为主要特征的全球气候变化导致降雨侵蚀力改变,从而影响区域土壤流失过程。因此,研究气候变化对降雨侵蚀力的影响,对适应和预防全球气候变化、争取环境外交主动权、制定农业发展战略具有积极作用。对相关研究成果进行了总结:国外相关研究由侧重单一的降雨量变化对降雨侵蚀力的影响,发展为气候变暖和土地利用类型的变化对土壤侵蚀环境的综合影响;国内相关研究起步较晚,侧重于不同区域降雨侵蚀力的计算,在长江流域,气候变化对降雨侵蚀力影响的相关研究较少。加强相关研究,既可为长江流域降雨侵蚀力的研究提供理论依据,又可为长江流域降雨侵蚀的防治和气候变化下水保措施的制定提供技术支撑。
Climate change affects the regional soil loss process by changing the rainfall erosivity.Investigations on the impact of climate change on rainfall erosivity is beneficial for adapting to global warming,being active in envi-ronment negotiation,and making agriculture development plans.We make a review on researches in this regard and results suggest that 1 ）research emphasized on the impact of rainfall amount variation on rainfall erosivity in the ini-tial stage,and then developed to focus on the comprehensive influence of climate and land use changes on regional soil erosion;2）researches in China started later and focused on the calculation of rainfall erosivity in different re-gions.Research on the impact of climate change on rainfall erosivity in the Yangtze River basin is inadequate.Im-proving researches in the Yangtze River basin could provide theoretical basis and support for the prevention of rain-fall erosion and policy-making on water and soil conservation measures in the Yangtze River basin.
