中文摘要： 大气CO2浓度持续升高不仅引起气候变化，更直接影响到作物生产。水稻是我国最重要的粮食作物之一，其对大气CO2浓度的生长响应关系到未来粮食安全。已有研究表明，在高CO2浓度条件下，水稻的生长发育发生了一定的变化，那么在未来高CO2情形下，是否需要调节或变化稻作栽培技术和品种选育策略？明确外界因子对CO2肥料效应的影响有急待解决的瓶颈问题，而FACE平台正好为此提供了一个非常好的检测手段。本研究拟通过在FACE平台上实施不同品种类型、生态环境、栽培技术等因子的田间试验，定量评估CO2与外界因子之间的互作效应，解析水稻生育及管理指标在这些互作效应影响下的动态变化规律，构建大气CO2浓度升高条件下水稻生产管理适应策略模型，为设计未来稻作生产应对策略提供有力的工具，对实现我国的水稻生产管理及相关的农业评估具有重要意义。

英文摘要： The [CO2] increase of global atmosphere is the main environmental factors associated with climate change. It is anticipated that elevated [CO2] can directly impact crops productivity. Rice is one of the most important crops as stable food in China, so the responses of growth to atmospheric [CO2] determines the food security in future. The previous studies approved that elevated [CO2] will change growth and development of rice.In this case, it is unclear whether we need to regulate or improve the rice cultivation technique and breeding strategy.It is essential to explore the other enviromental factors how to affect the fertilizer effect of elevated [CO2]. The FACE project povides an excellent opportunity to these researches.In this study, according to mul-field experiments under elevated [CO2] condition, a rice production management adaptation strategies model will be developed by quantitative evaluation of interaction effect between CO2 and external factors and analyzing the dynamic change law of rice growth and management indicators under such interaction effect. This model will provide a powerful tool for designing a better strategy of rice cultivation in future，which is important for rice production management and assessment.
