针对科尔沁沙地杨柴生物沙障的生存现状和生长动态规律,分析了经过不同预留盖度和留茬高度的平茬处理后杨柴生物沙障和林间草本植被的恢复情况及其防风固沙效益,结果表明：平茬对杨柴及其林间草本的生长均有极大的促进作用;在平茬后的第1年内,预留盖度10%和留茬高度0 cm（齐地刈割）对杨柴生长最为有利;综合风速和风蚀量的测定分析发现,在全面围封、林间草本较好的情况下,留茬盖度在10%已经完全能够满足生物沙障的生态防护功能。

Based on the current survival situations and growth dynamic law of Hedysarum fruticosum var.mongolicum sand barrier in Kerqin sandy land,the recovery state and wind-prevention and sand-fixation benefit of Hedysarum fruticosum var.mongolicum sand barrier and the herb have been analyzed after stumped by different reservation coverage and stubble height.The results show： Stumping can promote the growth of Hedysarum fruticosum var.mongolicum and the herb significantly.It is most favorable for the growth of Hedysarum fruticosum var.mongolicum with reservation coverage at 10% and stubble height at 0 cm in the first year of being stumped.Combined with the data of wind speed and erosion,reservation coverage at 10% can meet the ecological protective functions of sand barrier in the condition of good herb and complete enclosure.
