      摘要: 選取青海省4個農(nóng)業(yè)氣象觀測站的大杜鵑始、絕鳴物候期及氣候資料,分析了物候期變化及其對氣候變化的響應(yīng)情況。結(jié)果表明: 青海地形復(fù)雜且各地氣象條件不同,使得大杜鵑自然物候現(xiàn)象存在明顯的地域性。在溫度、日照和降水的共同影響下,除諾木洪始鳴期有不明顯推遲趨勢外,其他3站均有提早趨勢;絕鳴期均有推遲的趨勢;始、絕鳴期間隔日數(shù)均有延長的趨勢。大杜鵑始、絕鳴期的變化與氣候變暖的趨勢有一定的對應(yīng)關(guān)系,說明動物物候期對氣候變暖能作出一定的響應(yīng)。

      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
