摘要:
就浑善达克沙地高等级公路取土场采取的植被恢复与建设技术，提出了路域取土场植被恢复的优化配置和技术模式为平铺式砾石沙障+低立式菱形芦苇沙障+高立式沙柳沙障+樟子松造林。研究结果表明：取土场植被恢复技术模式的应用明显恢复了植被，樟子松成活率和保存率分别提高了30%和35%，植被覆盖度是流沙地的5倍，生物量增加了3.40~5.16倍，植被组成趋向于多样化、稳定化；取土场内的风速比是流沙的14.61%，输沙率减少了的91.7%，粗糙度是流沙的38.86倍，极大地减弱了近地表风速，减少了输沙量，改善了取土场下垫面的状况，改良土壤理化环境。
Abstract:
Refer to the vegetation restoration technology used in the sand cutting sites of the highway in Otindag Sandy Land, this paper provide an optimal allocation and technology mode of vegetation restoration in sand cutting sites of highway-gravel barrier & low rhombus reed sand-barrier & high salix sand-barrier & Pinus sylvestris var. mongolica forestation. The study showed that the survival rate and preservation rate have increased 30 percent and 35 percent to comparing plots; coverage of vegetation 5 times more than barren sand, composing of vegetation tended to more diversified and stabilized. The wind speed decrease rate was 14.61 percent of barren ones, sand transport rate have reduced 91.7 percent, the roughness of surface have increased 38.86 times than original one. The mode was not only greatly weakening the intensity of wind near surface, but also reduced the sand transport, and improved the soil characters.
