摘要
对中国喀喇昆仑山地区禾本科野生植物资源进行调查研究,结果表明该地区禾本科植物有18属,79种,4亚种,2变种;其中54%~59%为植物群落中的建群种或优势种;97.7%的种类为优良牧草,是该地区野生动物和家畜生存的重要食物来源;作物近缘种有赖草属（Leymus）和披碱草属（Elymus）植物约22种;防风固沙植物资源有芨芨草属（Achnatherum）、拂子茅属（Calamagrostis）、赖草属等约14种;水土保持植物资源有早熟禾属（Poa）、碱茅属（Puccinellia）等约26种;高海拔地区和北方冷季型草坪草资源有早熟禾属、羊茅属（Festuca）、（艹洽）草属（Koeleria）等约9种。
The results of investigation on wild gramineous plants in Karakorum Mountains of China showed that there are 18 genera,79 species,4 subspecies and 2 varieties.In which,around 45% to 49% are the dominants of the grassland;97.7% of them are high quality forages and the most important food of domestic and wild animals;22 species of Leymus and Elymus are the kindred of crops;14 species of Achnatherum,Phragmites,Calamagrostis and Leymus are the plant resource for windbreak and sand fixation;26 species of Poa and Puccinellia are the plant resource for water and soil erosion control;9 species of Poa,Festuca and Koeleria are the resource of cool season turfgrasses in high altitude area and northern area.
