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。
Based on the study of the authors’ soil erosion on the Loess Plateau, this article takes the global environment as a whole system to discuss a series of major environmental problems in modern soil erosion and global change. It is concluded that the accelerated anthropogenic erosion in the Loess Plateau occupies the leading position in modern soil erosion and is the result of the combined effect of the geosphere-biosphere. Man-made unreasonable economic activity is an important turning point from the development of natural erosion to man-made accelerated erosion.
