利用青海省共和盆地1957—2014年冬季积温和共和气象站1982—2014年春小麦、贵南气象站2001—2014年小油菜发育期资料，采用Pearson函数进行相关分析，并结合典型年份农作物发育期的对比分析，研究共和盆地内冬季积温对农作物发育期的影响。结果表明，1957—2014年共和盆地冬季积温以每10年49.7℃的速度增温；冬季积温与春小麦发育期呈明显的负相关，与小油菜绝大多数发育期呈正相关；春小麦积温典型偏高年份各平均发育期比典型偏低年份提前，且平均全生育期延长；小油菜积温典型偏高年份大多数平均发育期比典型偏低年份推迟，且平均全生育期缩短。掌握共和盆地冬季积温与作物发育期之间的关系及变化规律，可为物候预测及防灾减灾提供一定的科学依据。
利用青海省共和盆地1957—2014年鼕季積溫和共和氣象站1982—2014年春小麥、貴南氣象站2001—2014年小油菜髮育期資料，採用Pearson函數進行相關分析，併結閤典型年份農作物髮育期的對比分析，研究共和盆地內鼕季積溫對農作物髮育期的影響。結果錶明，1957—2014年共和盆地鼕季積溫以每10年49.7℃的速度增溫；鼕季積溫與春小麥髮育期呈明顯的負相關，與小油菜絕大多數髮育期呈正相關；春小麥積溫典型偏高年份各平均髮育期比典型偏低年份提前，且平均全生育期延長；小油菜積溫典型偏高年份大多數平均髮育期比典型偏低年份推遲，且平均全生育期縮短。掌握共和盆地鼕季積溫與作物髮育期之間的關繫及變化規律，可為物候預測及防災減災提供一定的科學依據。

Using the data of the ac-cumlacted temperature in winter from 1957 to 2014 in Gonghe Basin, and the data of the growing period of spring wheat from 1982 to 2014 in Gonghe meteorological station, and the data of the growing period of small rape from 2001 to 2014 in Guinan meteorological station, then correlation analysis of these data by the way of Pearson function, and combined with the typical year of crop development contrast analysis, to re-search the effects of accumlacted temper-ature in winter on crop growth period in Gonghe Basin. The results indicated that the accumulated temperature in winter increased at a rate of 49.7 ℃ every 10 years from 1957 to 2014 in Gonghe Basin. The accumlacted temperature in winter was negatively related to the growing period of spring wheat, and posi-tively related to the most of growing pe-riod of small rape. The growing period of spring wheat in typical years with higher winter accumulation temperature ad-vanced more than in the typical years with lower winter accumulation tempera-ture, and the whole growth period was extended. Most of growing period of small rape in typical years with higher winter accumulation temperature delayed more than in the typical years with lower winter accumulation temperature, and the whole growth period was shortened. It can provide a scientific basis on phe-nology forecast and disaster-related by mastering the relationship between accu-mulated temperature in winter and crop growing periods.
