摘要
黄土高原大部分地区因严重的土壤侵蚀，已丧失原有的自然景观，子午岭林区为追溯研究自然侵蚀和人为加速侵蚀与生态环境演变提供了研究基地。通过典型区考察和定位试验研究及实验室分析测试，分析研究了子午岭林区植被破坏与恢复对土壤侵蚀演变的影响；自然生态平衡下自然侵蚀和人为破坏植被耕垦的加速侵蚀特征及人为加速侵蚀与土壤退化过程等。
he natural landscape of loess plateau have been changed by severe soil erosion. The Zi-wuling forest region provides a good study area for tracing back eco-environmental change and natural erosion and man-made accelerated erosion. Using the methods of typical region investigation, experimental study in site,and chemical analysis of samples,impact of forest vegetation destruction and restoration on soil erosion change,characteristics of natural ero-sion under the condition of natural ecological balance,man-made accelerated erosion caused by forest vegetation destruction,and the processes of man-made accelerated erosion and soil degradation have been analysed and discussed
