摘　　要：该文结合作者对黄土高原土壤侵蚀的研究,把地球环境作为一个整体系统,来探讨现代土壤侵蚀与全球变化中的一系列重大环境问题。进而得出黄土高原的人为加速侵蚀在现代土壤侵蚀中占居主导地位,是地圈一生物圈综合作用的结果。人为不合理的经济活动,是由自然侵蚀发展为人为加速侵蚀的重要转折点。In the light of research on soil erosion on the Loess Plateau,a series of vital problem related to the global change and modern soil erosion is studied by considering the global environment as a whole system. Then,proceed to the conclusion that the manmade accelerated erosion has hold a dominant position in modern soil erosion, it is the result of comprehensive function of geosphere and biosphere. The irrational economic activity of mankind is the turning point from physical erosion to manmade accelerated erosion.
