| Abstract: | 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. |
