摘　　要：干旱河谷主要分布于地形封闭、谷地狭窄、植被稀少的河谷地段,其气温高蒸发大而湿度低,加之人类活动的影响,植被恢复困难、山体滑坡、泥石流、水土流失等生态问题日益严重。自70年代以来,研究者致力于对上述问题探讨与研究,但仍未形成成熟的治理体系及方法,且干旱河谷面积及程度有扩大的趋势,因此对干旱河谷进行深入的研究非常必要。文章分析四川西部干旱河谷的特点、形成及其发展趋势,并以眠江干旱河谷地区为研究对象,探讨了干旱河谷生境的分类区划,并针对各类型或亚类型提出了植被恢复与重建的途径、方法及其配置的植物种类,以期为四川西部干旱河谷地区生态修复、森林经营提供建议与启示。Arid river valleys are mainly distributed in valleys with closed terrain,narrow valleys,and sparse vegetation.The high temperature and high evaporation and low humidity,coupled with the impact of human activities,make vegetation restoration difficult,landslides,debris flows,soil erosion and other ecological problems are becoming more and more serious.Since the 1970 s,scholars had devoted themselves to discussing and researching the above-mentioned issues,but a mature governance system and methods had not yet been formed,and the area and extent of arid river valleys tended to expand.Therefore,it is necessary to conduct in-depth research on arid river valleys.The characteristics,formation and development trend of arid river valleys in western Sichuan were firstly analyzed in this paper,and takes the arid river valley area of the Minjiang River as the research object,the habitats of arid river valleys were classified and studied,and the ways and methods of vegetation restoration and reconstruction and the plant species configured for each type or subtype were put forward further,in order to provide suggestions and inspirations for ecological restoration and forest management in the arid valley area of Western Sichuan.
