Abstract:: We discussed the effects of different vegetation restoration measures on local soil environment based on the changes of soil physical and chemical properties. We selected 15 sets of sample plots in Kangbao County of Bashang Area, which include the measures of the returning cropland to forest and grassland, enclosing grassland and planting trees on grassland etc. The results from analysis of soil samples show that different vegetation restoration measures can improve soil properties at different degrees. For the restoration plots, the soil aggregates, soil porosity increased while the soil bulk density decreased; overgrazing makes the soil more compact. The abandoned cropland and grassland with higher vegetation coverage could reduce surface evaporation, which can increase soil water content; the root system of the trees inside surface soil would lower the soil moisture because the trees consumed a large amount of water. The higher vegetation coverage could effectively reduce soil erosion by wind, but the sparse vegetation within high trees and the wide gap between the shrub-line would increase the wind erosion. In the absence of fertilization, vegetation restoration could increase the contents of soil organic matter, total N and total P at different degrees, and the effect of the soil layer of 0—10 cm is higher than that of 10—20 cm, the contents of total N and total P in the soil after the conversion of farmland decreased because of excessive fertilization of farmland. The result shows that returning farmland to grassland and enclosing grassland are the better vegetation restoration measures in the local environment; the shrub should be cultivated more because it is the local species, but it should be planted combining with the arbor to increase vegetation coverage in high forest to enhance the windproof efficiency.
