| 摘 要： | 应用谱分析和周期图方法,探讨农业气象热量因子的周期波动,可取得较好的定量结果。上海等地的10℃活动积温、有效积温及其持续期的中短周期分析表明,农业气象热量因子具有7—8年和2—3年的周期波动,尤以8年周期最为显著。在三要素中,又以有效积温的周期波动最为稳定。 作者试图通过这个研究为农业气象预报和农业气候分析提供一些参考依据,并将谱分析方法引用于农业气象研究。

| Abstract: | Periodic fluctuation of agrometeorological thermal factors is investigated by using methods of spectrum analysis and periodogram. Analysis on the medium to short periods of active and effective accumulated daily mean temperature above 100C and it's duration in Shanghai, Tsingtao and Tientsin show that period lengths of about 7-8 and 2-3 years are prominent, especially that of 8 years. The periodic fluctuation of effective accumulated temperature is more stable. |
