中文摘要	沿岷江干旱河谷(流域-海拔梯度)剖面线设置"U"形样带3条,对植被和环境因子进行了调查,就岷江干旱河谷调查的48个样方,151个物种创建样地-物种数据库,应用TWINSPAN植被数量分类方法进行分类,并根据中国植被的分类原则和调查的样地物种组成特征,对数量分类的结果进行适度调整,建立了岷江干旱河谷地区植被(生态系统)分类系统.将岷江干旱河谷的植被划分为11个群系,18个群丛,均为灌丛单一类型.11个群系分别为:绣线菊灌丛、小花滇紫草灌丛、黄花亚菊灌丛、莸灌丛、驼绒藜灌丛、小马鞍羊蹄甲-白刺花灌丛、瑞香灌丛、西南野丁香灌丛、橿子栎灌丛、金花小檗-忍冬灌丛、华帚菊-小黄素馨灌丛.
英文摘要	The dry valley of the upper reaches of Minjiang river located in southwestern China is a ecological fragile transition zone from the Qinghai-Tibet plateau to Sichuan basin. It has a typical arid valley climate with complex topography and variable water and heat conditions. A long history of anthropogenic impact in combina-tion with a severe natural environment has resulted in degraded vegetation dominated by xeric shrubs. Shrubs, as a main vegetation type in this area plays a vital role in regional environmental protection and biodiversity con-servation. To provide a scientific base for future ecosystem restoration and management, three U-shaped transects were placed along altitude gradient in the dry valley of the Minjiang River. Vegetation and environmental factors were investigated. The data of 48 samples and 151 species were analyzed by using TWINSPAN classification method. The results of quantitative classification are adjusted artificially referring to the vegetation classification principles of China. The vegetation classification system of the dry valley of Minjiang river was established , which include 11 vegetation formations and 18 associations, and all of them are shrub types. They are described as below, respectively:Deciduous broad leaf shrubs sub type: Form. Spiraea Spp; Form. Ajania breviloba; Form. Ceratoides arborescens; Form. Bauhinia faberi , Sorphora vrcifolia; Form. Daphne spp; Form. Carydpteris spp; Form. Onosma farrerii; Form. Peptodermispurdomi; Form. Quercus cocciferoides; Form. Berberis zvilson-ae ,Lonicera japonica; Form. Pertya sinensis, Jasm-inum humile
