摘　　要：对青海省禾本科植物种类多样性、植物区系多样性、外部形态特征多样性以及植被类型多样性四个方面进行了分析研究。结果表明:野生禾本科植物有55属,246种,31变种或亚种;青海特有种10种2变种。区系组成有7个分布类型和5个变型。禾本科植物的根、茎、叶、花、果实都表现出多种多样的形态特征。以禾本科植物为建群种或优势种的植被类型有17个,在这些植被类型中伴生有其它多种禾本科植物。Diversity studies on species, plant flora, morphological characteristics and vegetation types indicated that there were about 55 genera of 246 species and 31 varieties or subspecies of wild Gramineae plants in Qinghai province. Among them, 10 species and 2 varieties were endemic species. According to plant flora composition, there were 7 distribution types and 5 subtypes. Root, stem, leaf, flower and fruit of Gramineae plants had their various morphological characteristics. Meanwhile, there were 17 vegetation types which Gramineae plants were dominant species, among these types, many other Gramineae plants were accompanying to grow.
