Abstract: In order to fully understand the impact of climate change on China's agriculture,and adapt to the possible impact of climate and resource changes,to provide suggestions for national food security,social harmony and stability and the stable and healthy economic development,and to provide guidance for related research work,the research results and existing problems outlined by domestic scholars on the impact of climate change on China’s agricultural climate resources and agricultural production are summarized in this paper.On this basis,this analysis looks forward to the work urgently needed in agricultural science research under the background of climate change in the future.The impacts of climate change on China’s agricultural climate resources are mainly reflected in several clearly defined aspects.With the increase of temperature,accumulated temperature and heat resources,the increase in the north is greater than that in the south.The light resources are decreasing,but there are regional differences.Annual precipitation changes are complex,with obvious regional differences,and tend to be decreasing.The research on the impact of climate change on agricultural production in China mainly focuses on the impact of changes in crop yield,planting systems and planting structure.The results show that the boundary between agricultural planting area and planting systems moves to the north,the effect of warming and drying on agricultural production does more harm than good,and the planting structure needs scientific adjustment.Under the background of climate change in China,impacts on the quality of agricultural products,cropping systems,and agricultural disasters,so measures should be further developed to cope with climate change and the experimental research of the applicable scope,including research on the climatic resources utilization technology,agricultural ecosystem environment regulate technology,the national food security key technology and development of the ability to adapt to climate change.
