摘　　要：前人对地质时期强土壤侵蚀发生期与气候期对应关系存在截然不同的三种看法,而对现代全球气候变暖对土壤侵蚀影响加大的看法则基本一致。在分析影响土壤侵蚀因子的基础上,提出未来全球气候变暖对土壤侵蚀产生影响的直接因子是降雨量,未来全球气候变暖仍存在不确定性;前人基于全球气候变暖的降雨变化研究结论是降雨变化不属全球同步性而存在区域差异,全球气候变暖的降雨变化具不确定性,因此土壤自然侵蚀量的增或减与气候变化的真正关系仍具不确定性。Researchers have three completely different views on corresponding relation between occurred period of severe soil erosion and climate period during geologic period,but the view on increase influence of global warming to soil erosion is basically the same.Based on the analysis of affecting factors of soil erosion,the paper puts forward: a) the direct factor of global warming affecting to soil erosion is precipitation and global warming still has uncertainty in future;b) based on the study on precipitation variation under the condition of global warming,our forefathers' conclusions are that the precipitation variation is not belong to global coincidence,but regional difference,and the precipitation variation is uncertainty.Thus,the real relationship between increase or decrease of natural soil erosion and climate change still has uncertainty.
