| 摘 要： | 黄土高原中部地区是典型的农业区，开荒扩种在本区表现突出，由于人为不合理的社会经济活动的影响，水土流失成为制约本区经济发展的突出问题。本文通过典型调查和总体分析相结合，对影响土壤侵蚀的人为因素进行了评价。认为土地利用结构不合理，人口的失控增长，森林植被的破坏以及工业化进程中对水土保持工作不十分重视等是人为加速土壤侵蚀的几个主要方面。

| Abstract: | The middle part of loess plateau is a typical agricultural area,and the most significant property of agriculture in this area is that the hilly and slop land are opened up to increase crop production.Therefore,soil and water loss is the major problem to limit the economic development in this area due to unreasonable social economic activities.The factors affecting soil erosion by human activities were evaluated through the combination of typical investigation and analysis.The results of the destroy of vegetation and underestimating soil and water conservation works in industrial development are the main factors affecting soil erosion by human activities. |
