摘  要：
[目的]研究近50年建昌县霜期设施农业生产中光热气候资源变化特征。[方法]利用近50年建昌县气候资料,采用常规数理统计方法,分析了1960～2009年建昌县霜期光照、气温变化趋势。[结果]1960～2009年建昌县霜期日照时数、日照百分率呈减少趋势,气候倾向率分别为-55.556 h/10 a、-2.39%/10 a,近50年分别减少了278 h和12%;1981、1982年发生了气候跃变,跃变前后日照时数、日照百分率分别减少161 h和7%。霜期气温总体呈升高趋势,平均气温、平均最高、最低气温气候倾向率分别为0.386、0.392和0.567℃/10 a,近50年分别上升了1.93、1.96和2.84℃;1987、1988年发生气温跃变,跃变前后霜期平均气温、平均最高、最低气温分别升高了1.3、1.2和1.7℃。近50年来,建昌霜期光照资源减少,而热量资源增加,形成光热互补。[结论]该研究为当地霜期设施农业的发展提供了气候依据。

摘  要：
[Objective] The aim was to study the characteristics of thermal climate resources changes of agricultural production during frost period in Jianchang County.[Method] By dint of Jianchang climate resources and routine numerical statistics method,the sunlight and temperature changes trend from 1960 to 2009 in Jianchang County were analyzed.[Result] The sunshine hours and sunshine percentage during frost period in Janchang County from 1960 to 2009 tended to decrease.The climate tendency rates were-55.556 h/10 a and-2.39%/10 a,respectively,287 h and 12% of deduction in recent 50 years.There was climate transition in 1981 and 1982.And there was a shortage of 161 h and 7% of sunshine hours and sunshine percentage before and after the transition.The temperature during frost period increased,the tendency rates of average temperature,average maximum and lowest temperature were 0.386,0.392 and 0.567 ℃/10 a,namely there was a growth of 1.93,1.96 and 2.84 ℃ in recent 50 years.There was temperature transition in 1987 and 1988.The average temperature,average maximum and lowest temperature increased by 1.3,1.2 and 1.7 ℃.In recent 50 years,sunshine resources during frost period in Jianchang were decreasing,while thermal resources were strengthening,forming complementary of light and heat.[Conclusion] The study provided climate accordance for the development of local facility agriculture during frost period.
