- Abstract:
- Soil nutrient properties in the Loess Plateau are largely influenced by re-vegetation. By calculating the soil nutrient index (SNI), this study evaluated the quantitative influence of typical plant communities of different re-vegetation types on soil nutrient properties in the hill and gully region of loess. Results of this study showed that the order of SNI among different vegetation types was trees(0.814) > brush(0.659) > grassland(0.364) > crap(0.220). Calculated SNI of different plant communities was in order of Caragana korshinski(0.777) > Populus simonii(0.658) > Robinia pseudoacacia(0.545) > Armeniaca(0.510) > Koeleria cristata (0.425) > Artemisia capillaris(0.310) > Hippophae rhamnoides (0.271) > Bothriochloa ischaemum(0.257) > Poa sphondylodes(0.249) > Glycine max(0.227) > Artemisia sacrorum (0.224) > Lespedeza daurica (0.103). The results indicated that different vegetation restoration measures can significantly improve soil nutrient properties. Significant difference in SNI was found among different brush communities. SNI of plant communty was found to be obviously higher than that in Glycine max crop community except for Artemisia sacrorum and Lespedeza daurica.
