Abstract: Abstracts: The paper aims to provide a scientific basis for rationally utilizing climate resource and distribution of agricultural production. Based on 9 meteorological stations’ meteorological data (such as daily temperature, precipitation and accumulated temperature) and disaster data (such as drought, rainstorm, dry-hot wind and frost) of Huang Shuihe Region from 1961 to 2010, the authors used the mathematical statistics method to study the change trend of climate resource of Huang Shuihe Region in recent 50 years. The results showed that: (1) the annual mean temperature of Huang Shuihe Region significantly increased, and the annual mean temperature change rate was 0.41℃/10 a, and the annual mean precipitation showed a weak increasing trend and its change tendency rate was 0.96 mm/10 a, the annual sunshine hours was 2596.6 h, which declining rate was 37.3 h/10 a; (2) the active accumulated temperature for daily mean temperature steadily through 0℃ and 10℃ showed increasing trends, with the rates of 78.7℃/10 a and 77.2℃/10 a, respectively; the non-frost period was from 94 to 155 days, which had a weak increasing rate of 4 d/10 a; (3) the drought showed a declining trend, with a rate of 0.91 times/10 a, but the trend of storm increased obviously, and the intensity index of dry hot wind was 15.5, which became obvious after 2000s.
