摘　　要：对若尔盖县轻度退化的露沙地、中度退化的固定和半固定沙化地开展恢复治理实验,提出了对应的治理方案。实验还发现:(1)露沙地对扦插柳条的成活具有抑制作用;(2)直径≥1.0 cm的高山柳插条成活率较高。In recent years,a series of restoration and control experiments have been conducted on slightly degraded sanded land and fixed and semi-fixed sanded land in Zoig~ County, and some suitable modes have been put forward for slightly and moderately sanded land. It was also found that （ 1 ） the survival rate of cutting willow was obviously reduced in sanded land. （2） Willows whose diameter were equal or greater than 1.0 cm had a higher survival rate.
