Climate change has a great impact on grain production in Northeast China,one of the major grain producing areas of China. So the study on the impacts of the chilling injury on crops in Northeast China is of great importance for food safety. Based on the dataset of soil surface temperature with 0.5°x0.5°lattice in China from 1981 to 2010,this paper analyzed the climate change trend in terms of the monthly mean temperature,the sum of monthly mean temperature during the growing season of the corn(May to September),the sum of decade(1980s - 2000s) monthly mean temperature anomaly,and other main meteorological factors. According to the industrial standard of " Technical specification for assessment of chilling injury to spring maize in Northern China"(QX/T 167 - 2012),it further analyzed the temporal and spatial variation of the chilling injury from 1981 ~ 2010,combining with the historical records of cold damage in Northeast China. The results showed that the climate became warmer during the corn growing season. The number of years,regions and frequencies of the chilling injury decreased significantly in past 30 years. In 1980s,chilling injury occurred every year in Northeast China. The 1990s was the turning point of chilling injury when the chilling injury decreased significantly,and the number of years of chilling injury decreased further in 2000s. The areas of mild chilling injury were mainly in the north - central and southeastern area of Heilongjiang province,where showed a low frequency of chilling injury(0.1 - 0.2 times / year). The reduction of cold damage had favorable conditions for continuous increase of corn yield in Northeast China. It concluded that under the climate warming background,the frequency of cold damage reduced but the occurrence was still uncertain.
