Abstract:
Aiming at the tricky problem in Baiying，Gansu Province in this study.Dealing with its salinized soil with high salt content，unsatisfactory soil structure and difficulty in vegetation restoration etc.problem，there are a set of various of vegetation combination experiment sets in this paper，such as tamarisk and amorpha，rose and stonecrop，9901 willow and rose and malian.Based on the same improved soil，the pH and total salt of the soil and salt ions were tested.At the same time，the survival rate of forest and the percentage of vegetation coverage were in the detected.The effects of different allocation model of trees brushes and grasses on soil salinization were studied.The results showed that the soil pH decreased the most obvious，0-20 cm，20-40 cm，40-60 cm soil pH decreased by 5.3%，4.7%，5.8%;the soil total salt decreased the most obvious，0-20 cm，20-40 cm，40-60 cm soil pH decreased by 88.37%,85.51%,76.97%;the contents of Na+，Cl- and HCO3- were significantly decreased，and the survival rate of tamarisk and amorpha were 98.5% and 88.6%，respectively.
