介绍了雪灾、风害、干旱、鼠虫草害、草地退化、沙化和水土流失等六类主要的草地灾害类型,并分析了其对草地畜牧业发展造成的影响。结果表明:草地灾害给草地畜牧业发展带来极大的负面效应,具体表现在对草地生态与环境的破坏;加剧草地承载压力;制约草地畜牧业的可持续发展等三个方面。

The main types of disasters in Nakchu of Tibet are snow, wind, drought, rodent and insect, detrimental weed, degradation and desertion of grassland, water and soil erosion et al. The grassland hazards to the development of grassland animal husbandry are analyzed. The results show that the grassland hazards bring about great negative influence to the development of the grassland animal husbandry. For example, they destroy the zoology and environment of grassland, aggravate load bearing pressure of grassland and restrict sustainable development of grassland.
