摘　　要：柽柳主要集中分布在额济纳河两岸,是绿洲和荒漠河岸林的主要建群种。本文采取全面平茬、团状平茬、隔株平茬3种不同方式,研究额济纳绿洲留茬30 cm的柽柳的复壮效果。结果表明:不同平茬方式下柽柳的生长状况不同。其中,全面平茬和团状平茬柽柳生长状况优于隔株平茬。林地土壤含水量在生长季呈先低后高的趋势。柽柳林下植被种类主要为骆驼刺和苦豆子,林下植被生长状况差异不明显。若平茬目的是复壮更新,综合考虑建议采用全面平茬。若所平茬的柽柳林考虑其功能以及平茬后的生长情况,建议采用团状平茬。Tamarix chinensis is a main constructive species of oasis and desert riverside forest,which mainly distributes on the riverside of the Ejin River.In this paper,three different stumping ways were applied to study the rejuvenation effect of remaining stubble for 30 cm in Ejin Banner oasis.The results showed that the growth status of Tamarix chinensis with full stumping and mass stumping was better than that with interval stumping.Soil water content of the forest land showed a trend from low to high in the growing season.The understory vegetation species of Tamarix chinensis forest was mainly Alhagi sparsifolia and Sophora alopecuroides,but there was no obvious difference in the growth status of understory vegetation.If the stumping purpose was to rejuvenate and renew,full stumping was better than other methods.Considering its function and growth after stumping,the mass stubble is the best way.
