Energy.,Climatic Change,Land Use Pol.,HESS等Top和知名刊物,平均影响因子3.05;单篇SCI最高他引80余次。主持或参与国家自然科学基金、国家重点研发计划、中国科学院先导专项A、中国科学院重点部署、国家发展改革委、地方委托项目等任务30余项。参与编写《第四次气候变化国家评估报告》和《中国气候与生态环境演变:2021》等国家报告,研究成果被美国科学促进会(AAAS)亮点报道。

研究领域和方向:

研究领域:气候变化影响与适应

研究方向:气候变化与人类活动对粮食安全的影响,气候变化未来风险预测与不确定性;未来适应气候变化技术与对策、农业物候等。

主要学术贡献:

(1)深入揭示了农田生态系统中与气候变化密切相关的机理过程,提出基于气温日较差的太阳辐射空间化模拟方法,改进和优化了作物模型生物物理过程参数,提高模型模拟的准确性。

(2)从单点、区域、国家等不同尺度,构建了作物生产适应气候变化的风险管理模型;通过集合概率预测的方法,开展了气候变化对我国主要粮食作物产量和水分利用的影响评估和不确定性分析,降低气候变化影响预测的不确定性。

(3)基于长序列历史观测数据,明晰了我国主要作物物候和产量时空分异特征,引入一阶差分方法,区分并量化了气候变化和作物管理措施对主要作物物候和产量变化的影响,厘定了气候变化和土地利用变化对我国主产区作物产量影响的相对贡献,提出粮食主产区适应气候变化不利影响的优化管理措施。
