Abstract

Grain production in Northeast China is an important guarantee of the national food security strategy. In recent years, affected by climate change and other factors, the instability and risk of grain production in Northeast China have increased. Responding positively to the impact of climate change on grain production has become the inherent requirement of stabilizing grain production in Northeast China. Based on the characteristics of climate change in Northeast China, this paper comprehensively analyzed the impact of climate change on grain production in Northeast China from the aspects of the growth, yield, planting system and distribution of main grain crops, and grain production potential. The results showed that :（1）The sunshine hours decreased significantly, the precipitation decreased, and the temperature increased significantly in Northeast China.（2）The frequency of drought and flood disasters in Northeast China increased, the accumulated area of disease and insect disasters increased, and the events of cold injury decreased significantly;（3）Climate change has changed the growth and development of major grain crops in Northeast China, promoted the expansion of planting limits to the north and east, and significantly improved the grain production potential with regional differences. In general, climate change is beneficial to grain production in Northeast China. In view of the comprehensive impact of climate change on grain production in Northeast China, based on the perspectives of pre-production, in-production and post-production of grain, this paper proposes response strategies to adapt to climate change and stabilize grain production in Northeast China, which is of great significance for ensuring grain security in Northeast China.
