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。
In the past, there were three different views on the correspondence between the occurrence of strong soil erosion and the climatic period in the geologic period, while the views on the impact of modern global warming on soil erosion were basically the same. Based on the analysis of factors affecting soil erosion, it is proposed that the direct factor influencing global climate warming on soil erosion is rainfall in the future, and there is still uncertainty about global warming in the future. Previous studies on rainfall changes based on global warming The conclusion is that there is a regional difference in the variation of rainfall but not global synchronization. Rainfall in global warming is uncertain. Therefore, the relationship between the increase and decrease of soil erosion and the true relationship of climate change is still uncertain.
