Based on the statistical indicators of 14 counties in the agricultural area of eastern Qinghai, the evaluation of exposure, sensitivity and adaptability were studied by using principal component analysis and weighted synthesis method. Then, the vulnerability of the risk-bearing body was analyzed by using GIS The barrier degree model was established to analyze the barrier degree of each indicator. The spatial distribution map of drought vulnerability in the eastern part of Qinghai and the barrier index of each indicator were obtained. The results show a trend of increasing from the central part to the north and south; drought vulnerability in the agricultural production environment shows the highest in the Naoshan area, followed by the Qianshan area, and the lowest in the Chuanshui area. According to the barrier degree index, precipitation, per capita net income of farmers and gross regional product are derived as the main causes of disaster management.
