文摘内容 Based on phenological records extracted from Chinese historical dairies, spring phenological series in the Yangtze River Delta (YRD) of China since 1834 is reconstructed. Together with temperature and phenological observation data, the indicating significance of spring phenological series to temperature changes is also analyzed. The results are shown as follows. (1) From 1834 to 1893, spring phenodate in the YRD was fluctuated and gradually delayed, but, advanced greatly at the end of the 19th century. From 1900 to 1990, although the decadal variations were found, no clear multi-decadal trend was detected. From 1990 to 2010, spring phenodate showed significantly advance again. Compared with the mean value for 1977-1996, the latest phenodate occurred in 1893 with 27 days delayed while the earliest phenodate occurred in 2007 with 17 days advanced. (2) The correlation coefficients between spring phenodates and temperatures from December to March and from January to March exceeded -0.75 and -0.80, respectively, indicating that our phenodate series well presents the long-term changes of winter and early spring (especially from January to March) tem-peratures. These results provide important basic data for the long-term integrated tempera-ture reconstruction over China in the future work.
