- Abstract:
-
Based on determination of litter layer and the physical properties of the main soil and water conservation tree species in typical black soil region, the results indicate that the soil bulk density increases and the total porosity reduces with the increase of soil depth, but no obvious change is found in the bare land. The soil bulk density is the minimum and the total porosity is the biggest under Salix pierotii forest, then soil improvement effect is most obvious, followed by Larix olgensis, Populus xiaohei, Pinus sylvestris var. Soil permeability is better under all kinds of trees than no trees, among them, soil permeability is the best under Salix pierotii forest. Soil and water conservation forests can effectively increase the soil water storage and permeable ability. The comprehensive evaluation results about soil hydrology effect show that Salix pierotii forest or Larix olgensis Henry is better than Populus xiaohei or Pinus sylvestris var.
