高寒半干旱地区人工草地建设中存在问题及对策——以西藏那曲地区为例

Problems and Countermeasures of the Artificial Grassland Construction in Cold and Semi-arid Areas of High Plateau

人工草地建设是解决高寒半干旱地区冷季缺草与草蓄平衡的一项关键因子,是保证该区草牧业可持续发展的关键措施。目前,人工草地建植不合理、不科学等问题严重制约了高寒半干旱地区人工草地的健康快速发展和牧草高效生产。以西藏那曲地区为例,对典型高寒半干旱地区人工草地现状及建设过程中存在问题进行了分析,阐述了目前那曲地区人工种草适宜的牧草品种,并探讨了人工草地建设和发展的对策措施。

Construction of artificial grassland is a key factor to solve the shortage of grass and forage balance in cold and semi - arid areas of high plateau ; and it is the key measure to ensure the sustainable development of grassland animal husbandry in this area. At present, a lot of artificial grassland constructions are neither reasonable nor scientific, which restrict the healthy and rapid development of artificial grassland in the cold and semi-arid areas of high plateau. In this research, with Naqu Area in Tibet as a case, problems in current status and ＇construction process of artificial grassland were analyzed in cold and semi-arid areas of high plateau. Suitable artificial forage species in Nagqu were elabo- rated. Countermeasures for the construction and development of artificial grassland were discussed.
