研究领域和研究方向：
森林生态学：森林群落生态学、树木种群生态学、植被遥感等。
--------------------------------------------------------------------------------
科研业绩：
1 植被遥感：利用多源数据开展了北方森林景观格局及动态特征，从区域尺度阐明了植被稳定与动态的辩证关系。利用地理信息系统技术对东北地区植被变迁及潜在植被进行了研究。同时对南方地区人工林生态系统的碳循环特征进行了解析。
2 群落与种群生态：对东北地区的阔叶红松林等进行了群落学特征及其对不同干扰的反应，分析了森林的更新过程及其同生境因子的关系。首次对亚高山岳桦林进行较为全面系统的调查研究，阐明了种群生长与更新机制。
3 生态恢复与群落过程：南方红壤丘陵地区生态系统退化后恢复过程中的物种多样性以及群落生产力特征，阐明了生态恢复的环境贡献。
4 干旱地区树木生理：通过生理特征及显微解剖学研究，分析了半干旱地区树木抗旱机理。
发表论文40余篇。
