科研業(yè)績
1、植被遙感：利用多源數(shù)據(jù)開展了北方森林景觀格局及動態(tài)特征，從區(qū)域尺度闡明了植被穩(wěn)定與動態(tài)的辯證關(guān)系。利用地理信息系統(tǒng)技術(shù)對東北地區(qū)植被變遷及潛在植被進行了研究。同時對南方地區(qū)人工林生態(tài)系統(tǒng)的碳循環(huán)特征進行了解析。
2、群落與種群生態(tài)：對東北地區(qū)的闊葉紅松林等進行了群落學(xué)特征及其對不同干擾的反應(yīng)，分析了森林的更新過程及其同生境因子的關(guān)系。首次對亞高山岳樺林進行較為全面系統(tǒng)的調(diào)查研究，闡明了種群生長與更新機制。
3、生態(tài)恢復(fù)與群落過程：南方紅壤丘陵地區(qū)生態(tài)系統(tǒng)退化后恢復(fù)過程中的物種多樣性以及群落生產(chǎn)力特征，闡明了生態(tài)恢復(fù)的環(huán)境貢獻。
4、干旱地區(qū)樹木生理：通過生理特征及顯微解剖學(xué)研究，分析了半干旱地區(qū)樹木抗旱機理。
5、發(fā)表論文40余篇。
