- Abstract:
- Soil erosion properties of forest-lands and reclaimed lands have been researched in this paper,using,observed data of large slope runoff plots and small watershes,The results have shown that soil erosion intensit in the forest land is very slight,soil erosion modulus is less than 15t/km2·a,runoff modulus is loss than 2400m3/km2·a.The factors of vegetation and soil are decided factors of affections soft erosion,but effect of rainfall and topography factors on soil erosion is not obvious.After vegetation being destroyed and reclaimed,natural erosion is being changed into accelerated erosion,erosion modulus and runoff moduius are above 10000t/km2·a and 27 480m3/km2·a inspectively.Effect of factors of rainfall and topography on soil erosion is obviousl.soil erosion modulus on the valley is two times that on hilly slope.And soil erosion amount of man-made accelerated erosion is very close relation to Ⅰ10 or Ⅰ15.It is 27.7% that in-creasing sediment of the valley slope erosion of coming from runoff and sediment of hilly slope.
