Abstract: Based on the statistical data of drought in China in the last 5 decades (1950 - 2000), the characteristics of occurrence and development of drought were studied. The drought-occurred areas and drought-induced disaster areas had been increasing in the latter 50 years of 20th century. Ratio between drought-induced disaster areas and drought-occurred areas had an increased trend. The drought occurred in China in 2000 was the most serious one since 1949, while the drought-occurred areas and drought-induced disaster areas reached at 40.5 million haand 26.8 million ha respectively. More than 60% of the drought-occurred areas and drought-induced disaster areas occurred in the Huang-Huai-Hai Region and the Middle and Lower Reaches of Yangtze River, which were the two most drought-induced disaster regions in China. According to the research results on drought prediction, the possibilities of drought occurrence in the future were analyzed and some precautions against drought were recommended.
