我区地处青藏高原,属半农半牧区,牲畜占全西藏的五分之一左右。虽然草原面积大,但由于受海拔高,气温低,牧草生长期短以及自然灾害频繁等各种因素的制约。因而,牧草供应的季节和年度间的不平衡性非常突出。尤其是重点农业县,草原面积小,牲畜超载严重,土地面积虽大,退耕不会种草,土地白茬休耕,牲畜饥饿过冬。为了改变这种状况,近几年来全区已大力开展人工种草,农区和半农半
My area is located in the Qinghai-Tibet Plateau, is a semi-agricultural and semi-pastoral areas, livestock accounted for about one-fifth of Tibet. Although grassland area is large, it is restricted by various factors such as high altitude, low temperature, short period of forage growth and frequent natural disasters.

Especially in key agricultural counties, grassland area is small, livestock overload is serious, land area is large, returning farmland will not grow grass, white stubble land fallow, and livestock will starve winter. In order to change this situation, the whole region has vigorously carried out artificial grass-planting, agricultural and semi-agricultural and semi-agricultural development in recent years
