摘要
水土流失是一个复杂的地貌过程 ,它受多种因素的影响。宁夏是水土流失严重的地区 ,也是新构造运动十分活跃的地区。通过宁夏地区水土流失和新构造运动的调查 ,分析了该地区新构造运动的特征 (包括类型、运动方向、强度、幅度以及演变历史等 )与该地区水土流失的关系 ,认为新构造运动不但是造成该地区水土流失严重的原因之一 ,而且也是控制本区水土流失区域差异的主要原因。这一研究将有助于水土保持研究的进一步深入。
The soil erosion is a complex geomorphological process caused by the endogenic and exogenic force. Ningxia is in the greatly active area of Neotectonics, and the degree of soil erosion in this area is very high. The relationship between the Neotectonics characters,including types, movement direction, intensity, range, and evolvement etc. and the soil erosion in the area was analyzed through the investigation on the soil erosion and Neotectonics. It is considered that Neotectonics is one of the reasons that impel the soil erosion to a significantly high degree, and that Neotectonics is the main factor that controls the regional diversity of the soil erosion in this area. This result will contribute to the development of the soil erosion research.
