摘    要:基于实地调查资料,对西藏境内怒江中游河谷的特殊荒漠型植被进行了研究。结果表明:(1)22个样方中有85种维管植物,其种子植物属的分布区类型以泛热带分布为主,占21.6%;种以中国特有分布中的西南特有成分为主,占53.2%;(2)生活型谱以矮高位芽植物为主,占41.2%,地面芽植物占40.0%;(3)采用Raunkiaer频度分析,出现在10个以上样方中的物种有白刺花、垫状卷柏、芸香草和阔盖中国蕨等,频度分别是68.2%、50.0%、50.0%、45.5%;(4)根据该河谷区域的气候特点、干旱程度、群落的生态外貌特征和生活型等,并结合《中国植被》对灌丛和荒漠的划分,认为该河谷区域的植被盖度极低,不属于灌丛类型,而是非地带性的干旱河谷型荒漠植被。

关 键 词:怒江中游  荒漠植被  干旱河谷

Abstract:Based on statistical analysis of the characteristics of the vegetation in the dry valley in middle reaches of the Nujiang River in Tibet, it is revealed that: (1) There are 85 vascular plant species belonging to 55 genera in 34 families, including 4 ferns belonging to 4 genera in 4 families; 1 species of Gymnosperm; 79 species of Angiosperm belonging to 50 genera in 29 families. 13 areal-types of the seed plants genera can be recognized, but mainly Pantropic (21.6%). 45 (57.0% of the total) species endemic ...
Keywords:Middle reaches of Nujiang River  Wasteland vegetation  Dry valley
