气候变暖对汾阳市冬小麦积温及生育期的影响

Effect of Climate Warming on Accumulated Temperature and Growth Period of Winter Wheat in Fenyang City

利用山西省汾阳市气象局1981—2010年气温观测资料和对应时段的冬小麦≥0℃积温及冬小麦生育期日数观测资料,分析了近30 a气候变暖对冬小麦≥0℃积温和生育期日数的影响。结果表明,汾阳市30 a年平均气温总体表现为增暖,冬小麦≥0℃积温上升,而生育期日数表现减少的趋势。

The temperature observation data, ≥ 0 ℃ accumulated temperature of the corresponding period and observation data of growth ,period days of winter wheat was used by Fenyang Meteorology Bureau of Shanxi Province from 1981 to 2010, the effect of climate warming on ≥0 ℃ accumulated temperature and growth period days of winter wheat was analyzed nearly 30 years. The results showed that the overall performance of the average temperature was wanning in Fenyang nearly 30 years, ≥0 ℃ accumulated temperature of winter wheat increased, growth period days of winter wheat was a decreasing trend.
