摘要 为了全面了解气候变化对中国农业的影响,以期为适应气候资源变化可能带来的影响,为国家粮食安全、社会和谐稳定和经济的平稳健康发展提供建议,并为相关研究工作的开展提供指导。文章归纳总结了国内学者关于气候变化对中国农业气候资源和农业生产影响的研究成果、存在的问题,在此基础上,科学展望未来气候变化背景下农业科学研究中亟需开展的工作内容。气候变化对中国农业气候资源的影响主要表现在:伴随着温度的升高,积温增加,热量资源增加,北方增幅大于南方;光资源基本呈减少趋势,但存在区域差异;年降水变化复杂,具有明显的区域性差异,多呈减少趋势。中国开展的气候变化对农业生产的影响研究主要集中于农作物产量、种植制度及种植结构变化的影响,结果显示,农业种植区及种植制度分界线北移,暖干化对农业生产的影响弊大于利,种植结构需要科学调整。气候变化背景下,中国关于气候变化对农产品品质、耕作制度、农业灾害影响等预案不足,应进一步开展气候变化应对措施及其适用范围的试验性研究,加强气候资源高效利用技术、农业生态系统环境调控技术、国家粮食安全关键技术研究和气候变化适应能力建设。 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.
