黄土及其上面发育的土壤无根系盘绕、固结,抗冲性很差,是导致黄土高原水土流失严重、生态环境恶化的重要内在原因.因此,研究该区土壤抗冲性的成因,是解决土壤侵蚀预测预报和水土保持综合治理的重大理论和实践问题.关于土壤抗冲性这一概念最早由朱显谟在60年代,根据黄土高原土壤抗侵蚀能力的特点,提出应把土壤抗蚀性和抗冲性明确区分开来进行研究,但有关这方面的系统研究至今尚未见报道.作者自1987年以来对黄土高原土壤剖面的
Loess and its development above the soil without root coiled, consolidation, poor impact resistance, is caused by the Loess Plateau serious soil erosion, the deterioration of the ecological environment is an important reason.Therefore, the study of the causes of soil erosion in this area is to solve Soil erosion prediction and comprehensive management of soil and water conservation of the major theoretical and practical issues.About the concept of soil erosion was first proposed by Zhu Xianmo in the 1960s, according to the characteristics of the soil erosion resistance of the Loess Plateau, proposed that the soil corrosion resistance and resistance However, no systematic research on this aspect has been reported until now.The author has studied the soil profile of Loess Plateau since 1987
