摘要
为了有效利用积温指导农业生产,对富裕县自1961-2014年共54a气温资料进行了统计分析,对≥10℃积温、初终日期的年际变化,年代际变化及保证率进行了研究。结果表明:富裕县≥10℃积温呈增加趋势,积温初日呈提前趋势,积温终日呈延后趋势,并给出了保证率等相关图标。
In order to application of accumulated temperature to guide agricultural production effectively, temperature data of Fuyu county was statisticed and analyzed during 1961-2014≥10℃ accumulated temperature, interannual variability of initial date and final date,interdecadal change of accumulated temperature and assurance were studied. The results showed that there was an increasing trend of ≥10℃ accumulated temperature, initial date advanced,final date decayed,and the related icon of assurance were put forward.
