Abstract: Based on the meteorological data, geographic information and socioeconomic data in Qinghai Province during 1961-2018, the risk regionalization of drought disaster in Qinghai Province was analyzed. The results are as follows: (1) The high risk of drought disasterinducing factors mainly occurred in eastern and southern parts of Qinghai Province, while the risk in western region was lower. (2) The vulnerability of drought disasterpregnant environment dereased gradually from northwest to southeast, and the vulnerability risk was higher in the northwest than in the southeast. (3) The areas with higher risk of disasterbearing body were mainly in the east of Qinghai Province. (4) The areas with higher disaster prevention and mitigation capabilities were mainly in northwest of Qinghai Province, and the lower ones were in the southern and eastern regions. (5) The comprehensive risk of drought disaster decreased from east to west, and the high risk area was mainly in the eastern region of Qinghai Province, and the low risk area was located in the western region. (6) The high risk area of drought disaster was mainly caused by the high risk of disastercausing factors and the high exposure of disasterbearing body. On the contrary, the low risk area was mainly caused by the low risk of disastercausing factors and the low exposure of the disasterbearing body. In addition, the better ability of disaster prevention and disaster alleviation was also one of the reasons.
