Abstract：It was studied on the effect of Vitex trifolia L. to block and fix sand, to improve physical and chemical nature and micro-climate in the sand land of southern China. The results show that the annual sand land erosion modulus in average is 24757 t/(km2·a) under vegetative cover of 10%-20% and 2 920 t/(km2·a) under vegetative cover of 40% ; compared to uncovered sandy land, on land covered by Vitex trifolia L. of 5-year growth soil organic matter is increased by 580% ,total N by 100% , total K by 28.6% , rapidly available K by 67.0% , the amount of fine sand less than 0.25 mm is increased by 98.7% , the maximum temperature could be lowered by 10 - 12℃ , and air humidity is increased by 1.2%, being propitious to the recovery of vegetation.
