摘　　要：将高寒山区白三叶／多年生黑麦草放牧草地植物组分分成白三叶、多年生黑麦草、单子叶杂草、阔叶杂草和死物质5种进行季节动态研究，进而对该草地牧草季节供给质量进行评价，找出生产管理上的不足并加以改进。该草地多年生黑麦草占据绝对优势，但豆科牧草含量不足；冬春季节死物质含量过高，夏秋季节利用强度不足。草地供给的牧草质量9月最高，播种牧草含量达79．90％，12月最差为44．68％；而可利用牧草含量最高为8月的97．04％，12月最低为45．55％。The seasonal dynamics of pastoral composition for pastures containing white clover, perennial ryegrass, monocotyledon weeds, broadleaf weeds and die mass were studied in white clover/perennial ryegrass pasture of frigid mountain area. The study included an evaluation of quality-this information were used to adjust and improve management, perennial ryegrass is the dominant species but white clover is short in the pasture, die mass were too more in winter and spring owing to not enough utilized during summer and autumn. Pasture quality is best in September, the proportion of seeding herbage is 79.9%, worst in December, 44.68%. Utilizable pasture is 97.04% in August, 45.55% in December.
