摘　　要：全新世以来黄土高原的侵蚀问题,历来是国内外学者研究的热门.黄土高原的环境演变和水土流失问题也是黄土高原研究的难点和重点.本研究从全新世以来黄土高原植被变化、降水量变化和土壤侵蚀量变化等几个方面,简要回顾了国内学者在上述领域的研究成果,针对领域内的成就和问题提出了粗浅看法和建议.文章认为,全新世以来黄土高原总体植被景观以草原为主;降水量也有显著变化,总体呈现东南高,西北低的态势,400 mm等降水量线大致沿东南—西北方向移动;土壤侵蚀强度也有阶段性变化,全新世早中期主要受自然因素影响,晚期受自然因素和人为因素双重影响.The erosive environment is one of popular questions in soil erosion research since Holocene on the Loess Plateau. By now scientists have done massive fruitful work on the subject, which considered the water and soil conservation in the Yellow River basin. From the aspects of vegetation, precipitation and soil erosion, this article reviews main research results of the erosive environment on the Plateau during geological periods, with some preliminary points of view and suggestions proposed. The authors consider that grasslands are major vegetation in the landscape of the Plateau since Holocene. During the period, the rainfall in the area had changed significantly, reflecting in the phenomenon that the 400 mm rainfall line was ever moving along in an approximately southeast-northwest direction. Periodic changes in the intensity of soil erosion were observed, and it should be particularly pointed out that during the early and mid Holocene, the erosion was mainly controlled by natural elements, while since late Holocene human activity played a more and more important role.
