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、不同类型立地进行了3个试验区的沙地造林试验，结果表明：3个试验区造林成活率都很高，固沙效果明显；陈巴尔虎旗和新巴尔虎旗试验区因牲畜啃食和浇水不及时而致保存率偏低；鄂温克旗采取网围栏全封措施，而保存率较高；3个试验区都有天然樟子松和杨树分布。

Expansion of sandy land & hazards in Hulunbeir are increasingly serious. In order to protect the Hulunbeir grassland and effectively control desertification of grassland, afforestation tests on sandy land in three test regions were conducted in different distribution region and different types of site in Hulunbeir. Result shows that : the three test regions have a high survival rate, and their fixing effects are significant ;preservation rate is low because of the livestock grazing and un- timely watering in Chen Barag Banner and Xin Barag Right Banner;Evenk Autonomous Banner which take full closure of the fence netting measures have the higher preservation rate;natural Pinus sylvestris var. mongolica and Populus spp. are distributed in 3 test regions.
