Abstract

Abstract: Under the background of global warming, the characteristics, spatial-temporal distribution, evolution trend and disaster-causing mechanism of drought disasters in Hubei province were analyzed. The results show that drought disasters occur in all seasons in Hubei province. Northwest Hubei including northwest, humpy ground in north, hilly area in central are the areas with the most drought disasters; While Southwest Hubei in south of the Three Gorges of Yangtze River is the area with the least drought disasters. July to October is the month with the most drought days, and January to May is the month with the least drought days. The frequency and intensity of drought disasters in Hubei province show a significant increase trend, which related to natural and geographical environment, human activities, water infrastructure construction and other factors. The threats of drought disasters to agricultural production, food security, drinking water security, ecological environment security and social development in Hubei province are becoming more and more prominent, so effective countermeasures should be taken.

Key words: drought disaster, spatial and temporal distribution, disaster-causing mechanism, impact, Hubei province
