Based on the daily meteorological data and maize planting data from 1980 to 2014 in eastern Jilin Province,Mann-Kendall mutation analysis,climate propensity and partial least-squares regression analysis were used to reveal the spatial and temporal evolution of chilling damage in the context of climate change.At the same time,the meteorological factors that affect chilling damage were analyzed.The results showed that:(1)heat condition had been improved in the past 35 years,and the chilling damage presented the decreasing trend;In the 1980 s,cold damage was affected by the weather such as low temperature overcast and rainy weather,early frost and so on,the occurrence frequency and intensity were high;In the 1990 s,with the increase of temperature and the anomalous increase of mid-term precipitation,the frequency of chilling damage decreased,but intensity increased;cold damage rarely occurred due to the significantly warmer temperature in the 21 st century,but did not rule out the possibility of extreme low temperatures in the region; (2)climate in eastern Jilin Province warmed up and the initial frost date was delayed,with more precipitation in the south and less in the north,and the sunshine hours were rising in eastern part and declining in the west;however,the frequency of chilling damage showed that the high frequency zone of chilling damage gradually extended from the central mountain area to high latitude area as the growth period progressed, which meant that high latitudes and high altitude areas became the high incidence areas of chilling damage; (3)maize was greatly affected by the low temperature in the emergence-tasseling stage,the impact of mete-orological factor on temperature decreased in the order:the amount of precipitation>sunshine hours>early frost days;more rainy weather in high altitude area was prone to chilling damage.
