Abstract: The impact of and adaptation to climate change has become an urgent issue for agriculture production. The temperature increased 1.5℃ in Northeast China (NEC) during the past 50 years, the increment is apparently higher than the average value over the whole China. Climate change brought about complicated impacts on crop production. NEC is one of the most important crop production bases in China; it takes a big role for food safety and security of China. It is of significance to discuss adaptation of agriculture to climate change on regional scale. The main characters of climate change and their impacts on agriculture in NEC during the past 50 years were analyzed in this study; the strategies and measures for adapting to and mitigating climate change in NEC are put forward, according to the impacts of GHGs emission and land-use in human activities on climate change. We emphasize that we should take positive action in agro-ecology, water resources utilization and environment protection, so as to protect the climate-environment and to fully utilize climate resources, thus to help the sustainable development of grain production in NEC.
