构建了植被物候精细刻画模型——构建了考虑温度、降水、积雪等气候变化因子的物候变化精细刻画模型，提出了物候模型引入气候变化因子的方法；建立了基于温度时间变化的常绿林物候模拟算法，解决了现有方法在常绿林物候变化模拟中无法应用的问题；构建了不同分辨率数据物候精细刻画的转化模型，揭示了地表异质性对降低物候数据不确定性的决定作用

揭示了气候变化与植被物候作用机制——揭示了冬季低温冷激对植被春季物候提前的制约作用，对春季物候提前的趋势提出了新的认识；发现了昼夜增温对植被秋季物候变化的反向驱动作用，从机制上解释了昼夜升温不对称性对秋季物候的影响；提出了风速减弱对高纬度植被秋季落叶期的推迟作用，揭示了风速变化对秋季物候的影响

提出了物候对生态系统碳循环影响观点——建立了植被冠层光合作用组分的物候变化信息分解模型，提出了物候研究中应该关注有效光合作用组分信息的观点；研发了基于降水累积效应的物候改进算法，支撑定量分解气候变化因子对碳循环的贡献；阐述了落叶林、常绿林对气候变化响应敏感性差异的机制，揭示了植被秋季物候对生态系统碳循环年际变化的决定作用
