- Abstract:

Planted Haloxylona mmodendron (H. ammodendron) stand has an important ecological effect on sand fixation and soil improvement. The changes of soil physicochemical properties were discussed under the time series and the vertical space in H. ammodendron plantation. The results showed that:(1) in the time series of 1973-2008, the changes of soil water content (SWC) and soil available potassiumfollowed the bimodal curve, and the peak values were observed in 1986 and 2003, respectively, the soil pH value of 0-40 cm layer increased at first and then decreased, while in 40-100 cm, the change followed the bimodal curve and the peak was observed in 1986 and 2003, respectively, the electrical conductivity (EC) showed in a wave type and the contents of soil organic carbon and available phosphorus increased at first and then decreased gradually, while the available nitrogen content increased; (2) In the vertical direction, the SWC and EC increased with the increase of depth, while the pH value and soil nutrient decreased. In summary, soil physical and chemical properties improved gradually overtime of plantation, and the effect was most obvious in 29-year stands, and then tended to be stable.
