摘要
Abstract
The control effect on wind erosion and sand cover by building sand-barrier was studied by taking Pinus sylvestris var. Mongolica as planting tree species. The results showed that building sand-barrier could promote the survival rate of the plantation up to 100% , which was significantly higher than that of the control. There were also significant differences in the growth rate of the Pinus sylvestris var. Mongolica plantation between building the sand-barrier and the control. The experiment showed that building the sand-barrier could promote the average sapling height, basal diameter and crown growth by 55.4% , 66. 6% and 60.1% respectively compared to the control. Sand-barrier building provided the morphology construction of the Pinus sylvestris var. Mongolica saplings with much better environment that significantly reduced the phenomena such as trunk bending, wind throw and drying up of the brnaches and turning yellow of the leaves due to the wind damage.关键词
