Abstract: Tibetan sheep in alpine fragile ecological environment was researched using the daily meteorological data during the period of 1961-2017,and the vulnerability of the sheep,environmental sensitivity and social and economic conditions were analyzed.The theory model of disaster,meteorological disaster risk estimation and ArcGIS spatial analysis were applied to lucubrate and estimate the sheep growth in different periods.The results showed that the risk in the alpine zone was higher in lambing and shearing periods but lower in the hills and on the gentle slope.In copulation and grass harvest periods,the risk was higher in the hills and valleys and on the gentle slope but lower in the nalpine zone.Thus it can be seen that terrain is a dominant factor affecting Tibetan sheep growth in the alpine zone.
