In order to study the soil nutrients and pH value at different revegetation stages in the edge of Tengger Desert,we selected six kinds of vegetation recovery phase soil from east to west,and tested pH value,organic matter total and available nutrients.The results showed that:in the process of sand dune fixation,soil organic matter and total nitrogen exhibited an increasing trend,respectively from 1.32 and 0.025g/kg ro 1.89 and 0.061 g/kg which reached a significant level.Available nitrogen and available potassium in the semi-fixed sand dunes were significantly increased.Due to the large number of plants growth soil available nitrogen and potassium contents in the fixed sand dunes were lower than that in the semi-fixed sand dunes.Desert grassland had a higher content in soil organic matter,total nitrogen and available nitrogen,and degraded desert grassland had slightly higher available phosphorus than that of the desert grassland.With the restoration process of degraded desert grassland,available phosphorus in the artificial Haloxylon forest declined and available potassium increased.Artificial Haloxylon Haloxylon forest had a low pH value.In vegetation recovery process,the presence of sand vegetation played a decisive role of nitrogen and organic matter enrichment.With the fixing of sand dunes and restoration of vegetation,soil organic matter,nitrogen and phosphorus contents increased,and the soil organic matter content had a strong positive correlation with soil total nitrogen,total phosphorus and available nitrogen content.
