of frost occurrence were analyzed. Through these analyses, frost risk during the flowering period at each site was estimated. Results suggested that first flowering dates (FFD) in the study area advanced significantly from 1963 to 2009 in North China. Over
to frost during the flowering period in spring, exhibited a decreasing trend in Northeast China and in North China, implying that frost risk has reduced over the past half century.

Vegetation greenness is a key indicator of terrestrial vegetation activity. To understand the variation in vegetation activity in spring across eastern China (EC), the AA. analysed the variation in the Normalised Difference Vegetation Index (NDVI
