摘要
为提高鄂尔多斯地区干旱半干旱困难立地条件下造林成活率和保存率,减少土壤侵蚀和风蚀,选择不同困难立地开展不同造林方法和模式试验。结果表明:干旱硬梁区造林成活率和保存率分别达80%和72%以上,其他造林成活率和保存率分别达到以上90%和85%以上;丘陵沟壑区土壤侵蚀量减少30%以上,沙区风蚀量减少30%以上。
In order to improve the survival rate and preservation rate of afforestation and reduce soil erosion and wind erosion in arid and semi-arid difficult sites in Ordos’s region,different afforestation methods and modes were tested in different difficult sites.The results showed that the survival rate and survival rate of afforestation were 80%and 72%,and that of other afforestation were 90%and 85%,respectively.Soil erosion in hilly-gully region was reduced by more than 30%,and wind erosion in sandy region was reduced by more than 30%.
