摘　　要：为了深入了解半干旱区路域边坡生态恢复初期土壤-植被系统演替特征,文章以山西太原绕城高速边坡生态修复示范工程为对象,结合对该示范工程边坡土壤-植被所开展的连续6年的野外定点生态监测实践,运用室外监测和室内数据分析,研究了土壤肥力、植被群落等特征指标的动态变化规律,为半干旱区公路边坡植被恢复提供参考依据。In order to further understand the features of soil-vegetation system succession on the preliminary stage of road slope ecological restoration in semi-arid regions, with the slope ecological restoration demonstration enginaedng of Shanxi Taiyuan beltway as the re- search object, combined with the field fixed-point ecological monitoring practice carded out for six consecutive years on the slope soil-vegetation of this demonstration engineering,the article used the outdoor monitoring and indoor data analysis to study the dynamic changes of soil fertility, vegetation communities and other characteristic indicators, thereby providing the reference for the vegetation restoration of semi-arid hiclhway slope.
