Analysis on Vegetation Restoration under Different Management Measures on Maowusu Sandy Land

From the viewpoints of population quantitative structure and biomass production,the vegetation restoration of Liujiayaotou Watershed at Zhaojiatang under different management measures was analyzed.The results showed that the integrated tree-grass planting had the best effect on vegetation restoration.The vegetation restoration on shrub land was better than that on high tree land.The effect was worse on pure poplar land.Sand-fixing by checkerboard fence could accelerate the fast restoration of vegetation,and spraying chemical sand-fixing agents had obvious effects on vegetation restoration on the slope facing the wind.
