Abstract
[Objective] The research aimed to analyze the variation trend of rainfall in Xingtai area in recent 48 years. [ Method] According to the annual and seasonal rainfall data in Xingtai, Nangong, Shahe and Neiqiu during 1963 -2010, by using the interannual variation rainfall line chart, trend chart and climatic variability, the variation Irend of rainfall in Xingtai area in recent 48 years was analyzed. [Result] The annual rainfall in Xingtai area during 1963 -2010 presented yearly decrease trend, and the decrease velocity was 18.0 mm/10a. The annual rainfalls in Xingtai, Nangong, Shahe and Neiqiu all presented the linear decrease trend. Except spring rainfall in Xingtai area in recent 48 years increased, the rainfalls in summer, autumn and winter all presented the linear decrease trend. The decrease velocity of summer rainfall was the maximum. The decrease of summer rainfall played decisive role in the rainfall decrease in the whole year. The decrease trend of winter rainfall wasn' t as obvious as that of autumn rainfall. [ Conclusion J The research provided theoretical basis for studying the climatic variation characteristics in Xingtai area under the climatic warming background.关键词
