In order to study the effect of different types of sand barriers on soil improvement in mobile dune in lakeside of Poyang Lake, two different types of sand barriers, corn straw and Vitex trigolia var. simplicifolia, were set, and the bare dune was taken as the control. The determination and analysis of the two types of sand barriers two years after the establishment showed that the Vitex trigolia var. simplicifolia sand barrier had the significant effect on the improvement of soil moisture content in 0-40 cm depth of soil, while the corn straw sand barrier had no significant effect on the soil moisture content; the contents of organic matter in the 0-20 cm soil layer in the corn straw sand barrier and Vitex trigolia var. simplicifolia sand barrier were 3.62 and 22.24 times of that of the control, respectively; these two kinds of sand barriers had the significant improvement effect on topsoil (p<0.05), and the Vitex trigolia var. simplicifolia sand barrier was better; however, there was no significant difference in the content of organic matter in 20-60 cm soil layer; the Vitex trigolia var. simplicifolia sand barrier could effectively improve the contents of total phosphorus, alkali-hydrolyzed nitrogen and available phosphorus, which were 3.58, 8.14 and 8.86 times of those of the control, but no obvious effect on soil total nitrogen was found, while corn straw barrier had no obvious effect on soil total nitrogen, total phosphorus, alkali-hydrolyzed nitrogen and available phosphorus. In conclusion, it is considered that the Vitex trigolia var. simplicifolia sand barrier is an ideal sand barrier material suitable for soil improvement of mobile dunes in this area.
