        男,1986年生,山东青州人,中国科学院地理科学与资源研究所副研究员。2015年毕业于中国科学院地理科学与资源研究所,获得理学博士学位。2015-2017年中国科学院遥感与数字地球研究所遥感科学国家重点实验室从事博士后研究工作。主持国家自然科学基金青年基金、国家重点研发计划项目专题和贫困县脱贫情况调研等项目。已合作发表论文30余篇。

  主要从事土地利用与农业发展方面的研究工作。目前致力于应用定量遥感、地理数学建模、空间统计与时空数据挖掘等方法,结合GIMMS3g、MODIS、SPOT-VGT、Landsat和Sentinel-2等卫星观测资料,解决气候变化-物候-生产力-粮食安全等全球变化与区域农业可持续发展领域关心的热点问题。研究兴趣聚焦:

  (1)农业地理信息与遥感;

  (2)脆弱生态区土地利用变化与人地系统耦合机理;

  (3)乡村地域系统的结构与功能优化 等。
