摘　　要：西藏是我国五大牧区之一,长期以来畜牧业一直依赖于天然草地,面临着冬春饲草供应不足的严峻问题,发展人工草地是解决当地季节性草畜不平衡、缓解草原放牧压力的重要措施。文章叙述了西藏地区发展人工草地的现状,以及在发展人工草地过程中存在的品种选择、牧草复种、播种后的土壤镇压、燕麦(Avena sativa L.)与箭豌豆(Vicia sativa L.)混播以及种子生产等五方面的问题,并提出了相应的解决途径。Tibet is one of the five major pastoral areas in China, its animal husbandry has long been dependent on natural grasslana. Faced with the severe problem of lack of forage supply in winter and spring, developing artificial grasslands is an important measure to solve the seasonal imbalance between livestock and grass and alleviate grazing pressure in grassland. This paper describes the status quo of the development of artificial grasslands in the Tibetan areas, as well as the five aspects of problems existed in the process of developing artificial grasslands, including cultivar selection, multiple cropping of forage grasses, soil compaction after sowing, mixture sowing of oat （Avena sativa L. ） and common vetch （ Vicia sativa L. ）, and seed production. It also puts forward the corresponding solutions.
