| Abstract: | Through more than 20 years artificial vegetation restoration and stopping grazing in Zhifanggou watershed, the plant communities had obvious effect on the soil nutrient by vegetation accumulation on the top of the soil with various effect of different plant. The content of nutrient in the profile of soil in 0-20 cm was higher than that in 20-40 cm, and the increasing effect on soil nutrient by herbage communities was clearer than by arboreal communities and by bush communities. In addition, the content of nitrogen had a linear correlativity with the organic matter content. The content of phosphorus had a linear correlativity with organic matter too. However, in 20-40 cm soil layer, the relationship of linear correlativity was not significant. |
