摘　　要：青海有菊科植物约６５属２４３种，产地及生态地理分布各异，反映了青海菊科植物区系的丰富性。在天然草地中占据比较重要地位的菊科牧草约３０属１３０种，其中除少数在群落中为建群种或优势种，大部分为伴生种。菊科中的部分种类有较高的饲用价值。There are about 65 genera, 243 species in Compositae in Qinghai. Their geographical distributions have nothing in common with each other, reflecting richness in Compositae flora of Qinghai. In the grassland, the major Compositae forage grasses occupying an important position are about 30 genera, 130 species. Most of them are companions. Part of them possess higher fodder value and good palatability, and are important sources of fodders for grazers.
