【摘要】分析了1982-2007年气候变暖对内蒙古呼和浩特、武川自然物候的影响,结果表明:①春季,土壤表层解冻呼和浩特晚于武川,其余物候呼和浩特早于武川;秋季物候均为武川早于呼和浩特.且两地物候间距均为“豆雁始(绝)见＞气象水文物候期＞植物始花(落叶)”；两地植物物候间呈显著的正相关,豆雁始(绝)见呈显著负相关,气象水文物候期间相关不显著；②两地年、春、秋季平均气温呈增加趋势,植物物候春季提前,秋季延迟趋势显著,与气温有很强的响应关系；豆雁在呼和浩特始见提前,绝见延迟,武川与此相反,豆雁与气温有一定的响应关系；气象水文物候期也具有春季提前,秋季延迟的趋势,与气温相关不显著.%Based on the data from 1982 to 2007 of air temperature and phenophases in Huhhot and Wuchuan, an analysis is made of the variation trends of plants, animals and the related hydro-meteorological phenophases in spring and autumn, and their relations to climate warming- The results show: (1) The spring soil thaw was later in Huhhot than in Wuchuan, and other phenophase was earlier in Huhhot than in Wuchuan; but in autumn, the phenophases in Wuchuan were earlier than in Huhhot. The phenophase difference between Huhhot and Wuchuan was: Douyan appearance (disappearance) >

hydrometeorological factors>florescence (defoliation); the relationship between florescence (defoliation) dates in Huhhot and Wuchuan was

positive significantly, and that of Douyan appearance (disappearance) was negative significantly, while that of hydrometeorological phenophases was not significant. (2) From 1982 to 2007, air temperature increased, the first flowering dates of plants advanced and the defoliating dates postponed, which have a strong relationship with temperature; the first appearance dates of Douyan in Huhhot advanced and the last appearance dates postponed, On the contrary in Wuchuan, there was a certain extent relationship with temperature; hydrometeorologicai phenophases also advanced in Spring and postponed in Autumn; and the relationship with temperature was not significant. 【总页数】5页(P299-303)
