摘要:

为揭示气候变暖对黄土高原城市典型木本植物物候的影响,以临汾合欢为研究对象,采用线性回归、小波分析、相关分析等方法,分析探讨气温、积温等气候因子对临汾合欢各物候期的影响。结果表明,由于气候变暖,临汾年平均气温呈上升趋势,1983—2021年上升了2.9℃;年降水量存在6年和15年2个周期。临汾合欢春季物候期提前,秋季物候期变化趋势不明显,生长季延长。气温和积温对合欢展叶始期和开花始期表现为极显著相关,对果实成熟期表现为显著相关。叶变色始期、落叶末期对气象条件反应不敏感,主要受果实成熟期的出现日期影响。

Abstract:

To reveal the influence of climate warming on the phenological phase of typical urban woody plants in loess plateau, the effects of climate factors such as temperature and accumulated temperature on phenological phase of Albizia julibrissin in Linfen were analyzed by linear regression, wavelet analysis and correlation analysis. The results showed that the annual average temperature in Linfen showed an increasing trend under the background of global warming, with an increase of 2.9℃ from 1983 to 2021. The annual average precipitation fluctuated with the interval of 6 years and 15 years, respectively. Spring phenological phase was earlier and autumn phenological phase had no obvious changing trend, resulting in increased growth season. The temperature and accumulated temperature were very significantly correlated with first leaf unfolding and first flowering, and were significantly correlated with fruit maturing. The first leaf coloration and the end of leaf fall were not sensitive to meteorological conditions, and were affected by the date of fruit ripening.
