- Abstract:
-
Because of serious soil erosion and degradation, the red soil hilly region has become a fragile ecological area. Based on 137Cs tracing technique and soil erosion estimation models, the soil erosion rate and corresponding effect were studied on the representative land utilization of Shaoyang, Hunan province. The result showed that the reference inventory of 137Cs in the study area was (1 920±125.6) Bq/m2. 137Cs concentrations’ distribution had obvious differentiation on the slope with different land use types and on the different parts of slope. The average soil erosion rate was also different, which decreased in the order of barren hill, local pine forest, soil and water conservation forest, citrus orchard, nursery garden changed from citrus orchard, nursery garden. The soil organic matter and other soil physicochemical properties also showed the same variation characteristics as soil erosion rate. On the different parts of slope, the soil erosion rate was relatively smaller on the top while relatively larger rate occurred on the middle and bottom of slope.
