本文利用全国21个站的木本植物物候资料和全国599个站的逐日气温资料,分析了1963-1988年中国木本植物物候对气温变化的响应,研究表明:26年来,植物春季物候期与春季气温在全国总体呈负相关,气温越高,物候期越提前;植物秋季物候期与秋季气温在全国呈正相关,但相关性没有春季物候期显著;我国木本植物物候生长季长度有明显的南一北向梯度,早春气温对植物物候生长季的影响比秋末气温对其影响更大。
In this paper, by using woody plants phenological data of 21 stations and daily temprature data of 599 stations throughout China, woody plants phenology responsed to temperature changes from 1963 to 1988 in China are analyzed. The re- sults prove that plant spring phenophase and spring temperature were overall negatively correlated throughout China: higher the air temperature, more advance the phenophase; plant autumn phenophase and autumn temperature were positively correlated throughout China, but the correlation was not as significant as spring phenophase; Growing season length of woody plants phe- nology has a clear south - north gradient. The impact of early spring temperature to phenology growing season is greater than end of autumn temperature to phenology growing season.
