- Title:
- Analysing on Natural Erosion and Man-made Accelerared Erosion in the Ziwuling Forest Area
- Keywords:
- the Ziwuling forest area; natural erosion; man-made accelerated erosion; eco-environment; vegetation destruction and restoration
- 摘要:
- 黄土高原的绝大部分地区，因严重的水土流失已丧失原有的自然景观，子午岭梢林区为研究追溯自然侵蚀和人为加速侵蚀的演变，提供了理想的场所。通过典型区的考察研究、大型径流场的定位观测研究和野外人工降雨试验等，分析研究了生态环境自然演变及人类活动对侵蚀的影响；剖析了子午岭林区自然侵蚀和人为加速侵蚀的演变；取得了新的论证资料。明确提出，随着人类对自然生态平衡破坏的加剧，自然侵蚀逐渐被人为加速侵蚀所替代，且后者逐渐占主导地位。
- Abstract:
- The most area of the loess plateau lost natural landscape caused by severe soil erosion, The Ziwuling forest area provides research place for tracing back change of natural erosion and man-made accelerated eresion.Using methods of survey research in typical tegion,site position obselvation of the large runoff plots and field simulated rainfall experiment,effect of natural change of eco-environment and human’s activiti on soil erosion and man-made accelerated ero-sion in tire Ziwuling forest area has been analysed.New argument data has been gotten.The au-thors point out that with intensifying of natural ecological balance destruction by human’s activi-ties,natural erosion gradually changed to man-made accelerated erosion,and man-made accel-crated gradually occupied dominat position in present soil erosion proecss.
