迄今,黄土高原的侵蚀和治理的研究已经取得很大的进展,但是侵蚀的规律还不能说是很清楚。之所以如此,首先是由于对影响的因素没有全面认识,其次是对各因素之间相互作用研究不够,如侵蚀因素多半局限于研究外力,内力因素则很少为研究者所注意。本文着重探讨内力因素,即新构造运动对侵蚀的影响和探求控制水土流失的措施。一、黄土高原的地质构造背景
So far, great progress has been made in the research on erosion and treatment of the Loess Plateau, but the law of erosion can not be said to be very clear. The first reason is that there is no comprehensive understanding of the influencing factors, and the second is the lack of research on the interaction among various factors. For example, the factors of erosion are mostly confined to the study of external forces and the internal forces are seldom for the researchers to pay attention to. This article focuses on the internal forces, namely, the impact of neotectonics on erosion and explore measures to control soil erosion. First, the geological structure of the Loess Plateau
