Advances in Impacts of Climate Change on Agricultural Production in China

Climate change, the main feature of which is global warming, has become one of the important environmental problems in the world. Also, it is a matter of general concern by the scientific community, governments and the social public. Climate change has brought a series of problems that beyond the range of nature changes in the earth itself, which poses a serious threat to human survival and social economy. Agriculture, especially crop production and food security, is one of the largest and the most direct industry affected by climate change. Therefore, the impact of climate change on agricultural production is always one of the hottest issues in the field of climate change. The present situation and progress in the research field of climate change impact on agricultural production in China is summarized systematically, introducing research methods, the progress in the experiment of greenhouse gases concentration enrichment in the atmosphere impact on crops, impacts and future trends of climate change on agricultural climate resources, the possible impact of climate change on crop growth and yield, impacts and future trends of climate change on agricultural planting system and varieties distribution, impact of climate change on crop potential productivity, impact of measures of adapting to climate change to increase the utilization ratio of agricultural climate resources and so on. On the basis, current problems in the impact assessment of climate change on agriculture is proposed too. In order to improve the reliability and rationality of the impact assessment for climate change on agriculture, more attention needs to be paid to the research of uncertainty of future climate change scenarios, model prediction and evaluation method. In addition, further researches are also needed about the impact of extreme weather events under climate change on agricultural production, the impact of climate change on agricultural plant diseases and insect pests, impacts of climate change on cash crops, fruit, animal husbandry and farmland ecosystem.
