摘要: 选取青海省4个农业气象观测站的大杜鹃始、绝鸣物候期及气候资料,分析了物候期变化及其对气候变化的响应情况。结果表明: 青海地形复杂且各地气象条件不同,使得大杜鹃自然物候现象存在明显的地域性。在温度、日照和降水的共同影响下,除诺木洪始鸣期有不明显推迟趋势外,其他3站均有提早趋势;绝鸣期均有推迟的趋势;始、绝鸣期间隔日数均有延长的趋势。大杜鹃始、绝鸣期的变化与气候变暖的趋势有一定的对应关系,说明动物物候期对气候变暖能作出一定的响应。

Abstract: Based on the data of the start and halt warble dates at 4 agro-meteorological observation stations in Qinghai, the response of the cuckoo's (Cuculus canorus) phenophase date to climate change was analyzed. The result show that: 1) there existed a regional difference in cuckoo's phenophase date; 2) except at Nuomuhong station, there was a trend of advancing of start warble date and delaying of halt warble date, and the interval day numbers from start warble to halt warble date prolonged at other three stations. This change trend was consistent with that of climate change, and thus we can conclude that the cuckoo?phenophase responds to the climate warming to some extent.

Key words: cuckoo, phenophase, climate change, response
