研究領域
1、環境地質災害的防治與研究領域，他的研究成果被國際滑坡地質災害界給與很高的評價，其代表著作為‘中國西北黃土區滑坡’（英文）， 被國際滑坡界廣為引用，另一代表作是為全球最大百科全書Encyclopedia Britannia撰寫的‘滑坡定義’一文，更是代表了他在國際該領域的研究水平和地位。
2、在氣候，環境變遷及風沙塵暴領域，他提出了第五地球磁化率生物源理論，該文在地學1區雜誌Quaternary Science Reviews發表，引用率達31次，至今仍居該雜誌榜首。另在1998年提出了中國西部風沙塵暴的新起源，其正確性被後來許多研究者證實，只因當時發表的期刊影響較小（Journal of Arid Environments），未能得到更廣泛的引用。最近，他與英國Derbyshire教授和美國Owen教授合作撰寫的Engineering Geology, Geomorphology and Geotechnics專著將進一步提高了他在這一領域的學術影響力。
