1. 提出了树木菌根类型调控亚热带森林的多样性与生产力关系的新机制，即在亚热带森林中，丛枝菌根（AM）树种具有更有效的养分获取策略，从而促进了其在亚热带混交林中的优势地位。随着树种多样性的增加，AM树种养分重吸收和凋落物分解速率同时增加；而外生菌根（EcM）树种的分解速率增加，养分重吸收却降低。养分获取策略的差异导致AM树种在高多样性样方中占据绝对优势。

2.发现植物氮重吸收和微生物分解驱动的有机质氮矿化之间存在此消彼长的联动效应，为植物养分利用策略研究提供了新的认知。随着年均温和降水量的下降，氮循环速度减缓；植物养分获取策略由以矿化过程为主导的获取性策略过渡为以重吸收为主导的保守性策略。

3.发现干旱区造林导致植物蒸腾作用上升，引起表层土壤钠含量上升，加剧土壤盐碱化，为准确评估人工林的生态环境效应提供了新视角。通过对塞罕坝不同林龄的落叶松人工林土壤微量元素及林下植被的监测，发现随着林龄上升，土壤干旱化、酸化和盐碱化加剧，并导致林下植被逐渐转向高钾低钠的物种。
