Study on Vegetation Change after Afforestation by Aerial Seeding on Sandy Land

Based on 3-year’s investigatin data of aerial seeding on Maerzhuang plot of Yanchi County,the changes of vegetation and dominant species population after aerial seeding were analyzed.The authors explored the relationship between vegetation change and habitat,and put forward some measures to prolong the growth phase of aerial-seeded plants.The results of the short-term investigation showed after aerial seeding,the species did not change a lot,but the vegetation coverage and biomass increased significantly.
