Abstract: Hubei is a subtropical province in the inland region of China， it has a specific response to drought-flood disasters. Based on the monthly temperature and rainfall data from 17 meteorological sites from 1970-2013， with linear regression， spatial interpolation， Mann-Kendall test， Morlet wavelet， the SPI index and the other mathematical statistics method， to analyze the spatiotemporal difference of climatic change and the characteristic of the responses of drought-flood disasters. The results showed：（ 1）In recent 44 years， the rainfall of Hubei reduced with the rate of 16. 16 mm/10 a and the annual average temperature rose with a speed of 0. 30 ℃ / 10 a.（ 2） From the Mann-Kendall test， it was found that the abrupt change of the temperature took place in 1994 and then the temperature rose up sharply.（ 3） The drought-flood disasters of Hubei were frequent， and the moderate， severe and extreme drought-flood disasters accounted a proportion of 31. 8% . The study proves that under the background of warming and drying， the responses to the climatic change had a characteristic of period and speciality， the droughtflood disasters embodied periodic law and the drought was prominent in recent years
