摘要: 在全球气候变暖的背景下,分析了湖北省干旱灾害的特点、时空分布规律、演变趋势和致灾机制。结果表明,湖北省干旱灾害四季皆有发生;鄂西北、鄂北岗地、鄂中丘陵区等鄂西北部地区是湖北省干旱灾害最多的地区,长江三峡以南的鄂西南地区是干旱灾害最少的地区;7–10月是湖北省干旱日最多的月份,1–5月则是最少的月份;湖北省干旱灾害发生的频率和强度呈现明显增加趋势,与自然和地理环境、人类活动、水利基础设施建设等因素有关。干旱灾害对湖北省农业生产、粮食安全、饮水安全、生态环境安全和社会发展的威胁越来越突出,应采取切实有效的对策措施。

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
