工作經歷	2008年當選為美國NOAA和科羅拉多大學綜合環境科學研究院（CIRES）院士（Fellow）。蘭州大學國家“****”特聘教授，博士生導師，
主講課程
學術組織兼職	擔任歐洲地球物理學會（EGU）《The Cryosphere》編輯，美國地球物理學會（AGU）《Journal of Geophysical Research – Earth Surface》副編輯，以及美國《Cold Regions Science and Technology》、中國《Sciences in Cold and Arid Regions》，《冰川凍土》和《氣候變化研究進展》等學術雜志編委，曾擔任美國AGU 《Journal of Geophysical Research》、美國《Arctic, Antarctic, and Alpine Research》、及《Cold Regions Science and Technology》客座主編。
研究成果	自1982年以來，張廷軍博士先后發表學術論文及書評140余篇，其中100多篇發表于國際SCI的學術雜志上。突出成果包括： 1）凍土分布：系統地研究了北半球多年凍土及地下冰分布特征，發現多年凍土區約占24%的北半球陸地面積，超飽和地下冰水當量約為10cm的等量海面變化值。應用衛星及數值模擬，首次系統地提示了北半球季節凍土的分布及其變化，該數據被廣泛應用為全球權威參考值，有關論文被聯合國氣象組織的政府間全球氣候變化(IPCC)第三次(2001)及第四次(2007)評估報告引用。他的論文《北半球多年凍土分布特征》一文被國際《極地地理》雜志評為30年來引用次數最高論文之一，并于2009年將此文在該雜志重新全文發表。 2）凍土與氣候變化：自二十世紀以來，極地地區多年凍土表面溫度升高了約2-7℃，然而同時期氣溫變化只有約1℃左右。因而對造成極地地區多年凍土升溫的主要原因在國際凍土界引起了廣泛的重視。張廷軍博士首先提出季節性積雪的變化是造成極地地區多年凍土升溫的主要原因。自1993年以來，他先后在這方面發表學術論文10余篇，其成果受到國內外同行的廣泛重視。美國地球物理學會最權威性雜志《地球物理綜述》(Reviewers of Geophysics)主編于2004年特邀張廷軍博士撰寫有關凍土與積雪方面的論文。“季節性積雪對土壤溫度場的影響”一文與2005年在該雜志發表并被廣泛應用。鑒于張廷軍博士在凍土與氣候變化方面的研究成果，美國航空航天署(NASA)及國家科學基金委員會(NSF)同時推薦他為國際政府間氣候變化(IPCC)第四次評估報告的主要執筆者。 3）凍土與碳循環：張廷軍博士及他的研究團隊提出由于氣候變暖，多年凍土退化，極地多年凍土地區在未來幾十年內將從目前的碳匯區變成碳源區。雖然氣候變暖，凍土活動層變厚，植物生長期延長，有利于植物生長，促進極地土壤的碳匯作用。但同時保留在多年凍土中的古代碳將參與地球～大氣間的碳循環，多年凍土中的古代碳將釋放于大氣，其總量將于未來幾十年內超過同期的土壤碳匯作用，使極地地區成為大氣的碳源，進一步增加大氣中的碳含量，對全球變化起到正反饋效應。 4）凍土與水循環：應用衛星遙感資料及有關實地觀測，張廷軍博士及他的研究團隊提供了大量的凍土時空分面資料，為流域及區域水循環評估及水文模型提供數據。同時，對西伯利亞多年凍土區自上個世紀三十年代以來河流流量增加的原因提出了新的解釋。他首次提出西伯利亞多年凍土區地下冰融化水很可能是其河流流量增加的主要原因，并應用有關實地觀測資料驗證了此觀點，為全面掌握及理解極地地區水文循環做出了貢獻。 5）土壤季節凍融循環及其與大氣間的相互作用：應用實地觀測，衛星遙感及數值模擬，張廷軍博士對北半球土壤季節凍融進行了系統的研究，編制了北半球30年（1971-2000年）土壤季節凍融逐月平均分布圖及其變化，揭示了北半球土壤季節凍結范圍在變小。自二十世紀初以來，土壤季節凍結范圍減少了約7%，此結果被廣泛引用，包括IPCC第四次評估報告。同時發現多年凍土區活動厚度在增加，非多年凍土區季節凍結厚度在減少。首次揭示土壤的季節凍融過程對深層土壤與大氣間的熱物質交換有去耦作用。土壤中水份季節性相變強度對大氣有約3-6個月的記錄及反饋效應。這對中長期氣候預報有著非常重要的意義，有待進一步研究。對多年凍土區熱融湖泊，湖泊融區，凍土遙感，土壤凍融過程數據模擬，大氣及云對區域能量平衡及積雪融化，極地地區氣候及其變化，季節性積雪，青藏高原凍土環境變化及其對工程建筑的影響等都有深入地研究。
獲得榮譽	自1993年以來，先后主持及參與了30多項美國自然科學基金（NSF），航空航天署（NASA），海洋大氣署（NOAA），和能源部（DOE）科研項目及多項國內科技部和基金委研究項目。多次組織國內外學術會議，在國內外學術會議、大專院校及科研機構作特邀學術報告。應邀參加了聯合國政府間氣候變化委員會（IPCC）第四次（2003-2007）和第五次（2009-2013）評估報告的編篆工作，是主要執筆者之一，主要負責全球凍土（多年凍土及季節凍土）的變化評估。政府間氣候變化委員會（IPCC）同美國前副總統（Al Gore）共同榮獲2007年度諾貝爾和平獎。獲中國科學院蘭州分院1985年度新長征突擊手，2008年度《Cold Regions Science and Technology》雜志最佳審稿獎（Top Reviewer Award）。他在《Polar Geography》的論文獲該雜志創刊以來(>30年)最高引用率獎（前五名之一）。
