| Abstract: | Tibetan Plateau is frequently attacked by different kinds of natural disasters.In this paper,spatial analysis was used to study the characteristics and temporal and spatial distribution law of natural disasters in Tibetan Plateau.The results showed that snow disaster is one of the most important natural disasters.There are two regions with comparatively high frequency of snow disasters in Tibetan Plateau.The first one locates in Lhoka of Tibetan,the second one lies in the adjacent area between south Qinghai and northwest Sichuan.Drought often happens in south Nakchu,North Shigatse and the area surrounding Lhasa.Northeast Chamdo and the adjacent area among Qinghai Sichuan and Tibet are also usually influenced by drought.The frequency of flood in Tibetan Plateau is relatively low.While the disaster of landslip,debris and landslide caused by flood can bring great destroy.Tibetan Plateau is the area of the highest frequency and largest area of strong wind、thunderstorm and hail in China. |
