机械沙障在呼伦贝尔沙地造林中的应用

摘要

Expansion ＆ damage of Hulunbeir sandyland are increasingly serious. In order to protect Hulunbeir prairie and effectively manage its desertification land, different governance afforestation for sandyland were set in different distribution area ＆ site types of Hulunbeir sandyland. Flat sand-barrier are suitable for smooth migratory dunes and vertical sand-barrier are suitable for higher migratory dunes.%呼伦贝尔沙地扩展和危害日益严重，为了保护呼伦贝尔大草原，有效治理草原沙漠化土地，在呼伦贝尔沙地不同分布区、不同立地类型建立不同的治理造林模式。经试验研究，平铺式沙障适合平缓流动沙丘，直立式沙障适合高大的流动沙丘。
