摘　　要：植被恢复是干旱河谷生态建设的重点和难点,而物种的选择是植被恢复的基础和关键.就目前干旱河谷区植被恢复研究存在的问题进行总结,并从生物学特性、资源概况、利用现状以及生态价值4个角度阐述蔷薇属植物在干旱河谷区的独特优势,为干旱河谷生态恢复过程中物种的选择研究提供新思路.从生长习性来看,蔷薇属植物作为干旱河谷区的优势乡土灌木,适合在极端贫瘠的土壤中种植,其庞大发达根系、丰富的生物量有利于改良区域土壤结构、提高土壤肥力、保持水土和增加生物多样性.通过文献调研发现,该属植物资源丰富,用途广泛,可在生态修复的同时利用其独特的花色、花香发展当地生态旅游,亦可为化工产品的生产提供原料.因此,蔷薇属植物的生态经济景观效益俱佳,是治理干旱河谷脆弱生态环境的有效植物材料,在植被恢复与重建方面具有较好的研究价值和应用前景.未来,应将植被恢复与改善生态和发展经济相结合,与乡土资源和传统景观相结合,兼顾生态、经济和社会三大效益,实现筑牢生态屏障与群众致富共赢.(图1表2参106)Vegetation restoration is the focus of ecological construction in dry valleys.The selection of species is the basis and key to vegetation restoration.This paper summarizes the existing problems in the research of vegetation restoration in dry valleys and elaborates on the unique advantages of Rosa plants in the region.The aim is to provide new ideas for the study of species selection in the process of ecological restoration in dry valleys.From the perspective of growth habits,Rosa plants are the dominant native shrubs in dry valley areas and are suitable for planting in extremely poor soil.Their large and developed root systems and abundant biomass are conducive to improving soil,maintaining water and soil,and increasing biodiversity.The available literature indicates that this genus of plants is rich in resources and has a wide range of uses.Its’unique colors and fragrances can enhance local ecotourism during ecological restoration and can also provide raw materials for the production of chemical products.Therefore,the Rosa plant is an effective plant material for treating the fragile ecological environment of dry valleys and has excellent ecological and economic landscape benefits.It has good research value and application prospects for vegetation restoration and reconstruction.Future vegetation restoration should be combined with the ecological improvement and economic development,as well as local resources and traditional landscapes.Comprehensive consideration of the three major benefits of ecology,economy,and society,achieving a win-win situation of building a strong barrier,and enriching peoples’lives should prompt ecological restoration research involving Rosa plants.
