摘　　要：植被资源调查为植被资源的保护与沙漠化治理提供基础理论依据。本研究采用样线法对柴达木盆地植被的资源现状进行调查,并对其盆地植被群落情况进行分析。结果表明:(1)柴达木盆地植被类型主要以沙生植被和盐生植被为主,其中密花柽柳(Tamarix arceuthoides)、蒿叶猪毛菜(Salsola abrotanoides)和唐古特白刺(Nitraria tangutorum)为当地优势灌木。藜科、菊科、禾本科、豆科、蒺藜科为当地优势科种。(2)根据植被分布特点,柴达木盆地植被可分为三大区域和六大植被群落类型。The investigation of vegetation resources provides basic theoretical basis for the protection of vegetation resources and desertification control. In this study,a line transect method was used to investigate the resources status about vegetation and analyze its communities and degree of desertification in Tsaidam Basin. According to the analysis,there are some conclusions in the study. Firstly,the vegetations are mainly composed of sandy plants and halophytic plants. The local preponderant shrubs are Tamarix arceuthoides,Salsola abrotanoides and Nitraria tangutorum. The local dominant families are Chenopodiaceae,Compositae,Poaceae,leguminosae and Zygophyllaceae. Secondly,according to the characteristics of the vegetation distribution,the sandy vegetation could be divided into three regions and six types of communities.
