Abstract
[Objective ] The changes trend of temperature and frost-free period in Xinglai in recent 53 years were studir-d. [ Method ] Accord ing to the climate data of Xinglai City and Nangong County in 1958-2010, the changes trend of the temperature, ihe first and the last frost day, and the frost-free days in Xinglai was studied. The characteristics of the changes of temperature and frost-free days in Xingtai in recent 53 years were studied. [Result] No matter city or countryside, the annual average temperature was irwreasing. The climate tendency rale in Xingtai and Nangong was about 0.5 and 0.2 ℃ /10a. Especially, since 1996, the annual average temperature increasing trend was about I. 0 ℃/10a. The average temperature of the four seasons was also climbing and was similar to the increase span of the annual average tempera ture. The annual average temperature increasing span was the largest in winter. And the increase of the annual average temperature in winter was the largest and the increase of the annual average temperature was caused by the increase of the average temperature in winter. The urban annual average temperature was obviously higher than that of the countryside, which reflected the characteristics of tropical island effect. No matter in the city or the countryside, the early frost day, final frost day and frost-free day showed same tendency, namely the delay of early frost day, advance of Gnat-frost day, extension of fowl-zero day; the day of urban early frost was late than that of the countryside, and the final frost day was earlier than that of the countryside, the frost-zero days were longer than thai of countryside and indirectly influenced by urban heal effect. [Conclusion] The study provided theoretical basis for Ihe development and application of thermal resources in Xingtai.关键词
