研究成果

根據現代氣候學研究,亞洲夏季風的水汽輸送西北邊界位於青藏高原東北部的柴達木盆地、祁連山及河西走廊中東部地區,該區域處於戈壁大漠和高原之間的過渡地帶,其現代氣候過程受到亞洲季風和西風帶氣流的雙重影響,千-百年尺度氣候變化過程複雜,在長時間尺度上,該區域的氣候變化和湖泊演化對季風系統和西風帶環流的響應與機制是過去全球變化研究中一個重要的科學問題。李育的研究方向是夏季風西北緣長時間尺度環境變化、冬夏季風演化和湖泊演化及其機制。研究材料及方法包括:河西走廊豬野澤、鹽池等全新世湖泊記錄,CCSM3.0古氣候模式和湖泊能量-水量平衡模型。創新點包括:(1)在東、中亞地區使用古氣候模式和湖泊模型,模擬了長時間尺度冬、夏季風及湖泊水位變化過程;(2)使用河西走廊豬野澤和鹽池等全新世湖泊記錄證實了亞洲夏季風對季風邊緣區的影響;(3)將該區域現代氣候過程方法運用於古氣候學研究,並結合古氣候模擬證實了湖泊表面蒸發對千年尺度湖泊演化的影響。
(1)季風邊緣區長尺度冬夏季風及湖泊演化模擬
古氣候模擬與湖泊所記錄的古氣候信息提取是研究過去全球變化的兩種重要手段。模擬方法側重於古氣候變化機制研究,而湖泊記錄主要用於古氣候重建,將二者結合起來靈活運用是理解古氣候變化和長尺度水循環過程及機制的重要途徑。
我國冬季極端寒冷事件和冰凍災害與亞洲冬季風的突變有密切聯繫,探索長時間尺度東亞冬季風變化機制,有助於理解和預測全球變暖背景下冬季風變化趨勢。我國之前研究已獲取大量冬季風重建的結果,但是這些結果存在差異且很少涉及冬季風演化機制。李育研究組使用the Community Climate System Model version 3 (CCSM3)耦合氣候模式,並採用連續氣候模擬方法,連續模擬了全新世期間東亞冬季風的演化序列,在此基礎上對比了模擬冬季風強度與戈壁沙漠南緣的全新世風成沉積記錄,二者具有較好一致性,進一步證實了該項模擬的可靠性。氣候模擬結果所揭示的全新世氣候變化機製表明:軌道參數所驅動的海、陸溫度及氣壓差異是全新世亞洲冬季風演化的主因,除此之外,全新世早期勞倫太德冰蓋和北大西洋冰川融水也是促使早全新世東亞冬季風較強的重要因素。在現代全球變暖背景下,軌道參數和正在消融的北半球高緯度冰川本應伴隨較弱的冬季風強度,但是近10年來北半球冬季極端低溫事件頻發,可能與人類活動有關。
李育等選擇了將古氣候模式CCSM 3.0和湖泊能量與水量平衡模擬相結合的方式,在東、中亞地區模擬了LGM、早、中、晚全新世湖泊水位變化的過程,並將模擬結果與該區的湖泊水位重建結果進行了對比,二者顯示了一致性,在此基礎上討論了東亞季風區和中亞乾旱區全新世湖泊水位演化的差異及其機理。這項研究為理解季風邊緣區湖泊水循環變化過程做出了重要貢獻。研究成果發表於《Climate Dynamics》(一區)、《Quaternary Science Reviews》(一區)、《Global and Planetary Change》(二區)等國際權威雜誌。
(2)河西走廊古湖泊學研究
石羊河流域位於青藏高原東北緣、河西走廊東段地區,處於我國三大自然區(東部季風區、西北乾旱區和青藏高原區)的交匯地帶。豬野澤為石羊河流域終端湖泊,豬野澤長時間尺度湖泊演化研究,對於理解三大自然區過渡地帶的氣候變化過程及機理有重要作用。前人在該區域展開了大量研究,但是關於全新世中期的氣候及環境狀況存在一些分歧。李育等通過石羊河流域終端湖豬野澤不同位置沉積記錄及孢粉組合的對比研究,並結合孢粉濃縮物測年和其他年代學結果對比的方法,推進了豬野澤千年尺度環境變化研究。結果顯示:豬野澤地區早全新世環境相對濕潤,中全新世階段水熱組合較為適宜,而晚全新世環境趨於乾旱。中全新世期間存在一次百年尺度的乾旱事件,不同位置的沉積剖面的砂層沉積是這次乾旱事件的主要標誌物。豬野澤全新世環境變化主要受亞洲夏季風演化控制,同時也受到中緯度西風帶氣候變化的影響,體現了季風邊緣區湖泊演化的特殊性。主要成果發表於《Boreas》、《Palaeogeography, Palaeoclimatology, Palaeoecolog》、《中國科學》和《科學通報》等著名期刊。
鹽池位於河西走廊中段,是現代亞洲夏季風水汽輸送可到達的邊界區域。李育等使用孢粉濃縮物測年、礦物分析、地球化學指標等方法研究了鹽池晚冰期以來湖泊沉積物,結果顯示:鹽池晚冰期以來湖泊演化過程與青藏高原區和典型季風區的古氣候記錄具有一致性,晚冰期及早全新世湖泊擴張,中、晚全新世期間湖泊退縮明顯,這種變化顯示了千年尺度亞洲夏季風對該區域的影響,證明了夏季風北部邊界擺動的事實。主要成果發表於《Palaeogeography, Palaeoclimatology, Palaeoecology》和《地理學報》等著名期刊。
(3)乾旱、半乾旱區湖泊水循環的現代過程研究
氣候變化的現代過程是研究古氣候變化的基礎。亞洲季風邊緣區受到季風與西風氣流的雙重影響,其古氣候變化體現出了一定的複雜性。為探索季風邊緣區古氣候變化的機制,李育等通過季風邊緣區現代降水和過程研究,進一步探討了該區域氣候變化與兩大氣候系統的聯繫,並通過現代過程的研究得出該區長尺度氣候變化也可能受到兩大氣候系統相互作用的影響。
同時,蒸發作用是湖泊水循環的重要環節,以往的長尺度湖泊演化研究中,蒸發作用影響僅被停留在討論之中。為了更加準確地了解蒸發作用對長尺度湖泊演化的影響,李育等研究了豬野澤和青海湖地區的現代蒸發資料,發現這兩個湖泊現代蒸發過程的受控因素不同,這種差異可能會影響這兩個湖泊長尺度演化過程。主要成果發表於《地理學報》、《Journal of Asian Earth Sciences》、《Environmental Earth Sciences》等著名期刊。
豬野澤及河西走廊晚第四紀文獻索引及引用指南
Reference guide of the Late Quaternary climate change for Zhuye Lake and the Hexi Corridor in the Asian monsoon marginal zones, northwest China
河西走廊及豬野澤位於青藏高原北緣的祁連山南麓,處於戈壁大漠和高原之間的過渡地帶。在氣候上,該區域處於亞洲夏季風的西北緣,部分夏季降水來源於夏季風水汽輸送,同時主要受控於中緯度西風帶環流,是季風-西風相互作用的關鍵區域。近年來,該區域晚第四紀環境變化研究取得了大量進展,推動了長時間尺度季風和西風演化的研究,但還存在一些爭議。一個主要問題就是該區域文獻量比較大,與第四紀相關的論文較多,且學科較雜,不利於相關學者了解該區域的研究狀況。本索引旨在整理該區域近年來各相關學科的主要文獻,便於第四紀科學研究者了解該區域狀況,同時該索引也代表了蘭州大學晚第四紀研究在該區域的進展情況。
Zhuye Lake and the Hexi Corridor are located in the northern edge of the Qinghai-Tibetan Plateau, on the northern side of the Qilian Mountains, while in a transition zone between the Gobi desert and highland. The area is in the northwest margin of the Asian summer monsoon. Some summer precipitation is from the summer monsoon moisture transport, while the area is mainly controlled by the mid-latitude westerly circulation, which is a key area for studies on the interactions between the summer monsoon and the westerlies. In recent years, scientists have made a lot of progress on the late Quaternary environmental changes in the area, and promoted the study of long-term monsoon and westerly winds changes, but there are still some controversies. A major problem is that there are a large volume of papers in the area that are related to the Quaternary science while various subjects are involved. That is not conducive for scholars to understand the late Quaternary conditions in the area. The reference guide is designed to organize literatures in relevant disciplines, which is good for scientists to understand the late Quaternary environments easily, while the guide also represents the research progress of Lanzhou University on the late Quaternary environments.
1豬野澤千年尺度環境變化
豬野澤湖泊沉積物環境代用指標記錄顯示,豬野澤地區早全新世環境相對濕潤,中全新世階段水熱組合較為適宜,而晚全新世環境趨於乾旱。中全新世期間存在一次百年尺度的乾旱事件,不同位置的沉積剖面的砂層沉積是這次乾旱事件的主要標誌物。豬野澤全新世環境變化主要受亞洲夏季風演化控制,同時也受到中緯度西風帶氣候變化的影響,體現了季風邊緣區湖泊演化的特殊性。

2鹽池千年尺度氣候變化
鹽池晚冰期以來湖泊演化過程與青藏高原區和典型季風區的古氣候記錄具有一致性,晚冰期及早全新世湖泊擴張,中、晚全新世期間湖泊退縮明顯,這種變化顯示了千年尺度亞洲夏季風對該區域的影響,證明了夏季風北部邊界擺動的事實。

3花海千年尺度氣候變化
花海沉積物記錄的千年尺度環境變化表現為,早全新世環境流域徑流較大,流域性侵蝕及沉積過程較劇烈;中全新世有效濕度較高,晚全新世環境趨於乾旱。這種水分條件的變化與早全新世較強的亞洲季風所帶來的較多降水有關,從而增加了徑流量和流域性的侵蝕量。這種全新世水分條件變化模式,也受到了中緯度西風帶的影響。

4豬野澤氣候變化周期
豬野澤湖泊沉積物古環境代用指標記錄顯示,該區域有明顯的~256、~512、~1024年氣候循環周期,這與典型亞洲夏季風區全新世千年尺度和百年尺度氣候循環周期一致。同時,該區域湖泊沉積物中也記錄了明顯的北大西洋浮冰碎屑事件(Bond Events),這與該事件的全球性有關,體現了季風邊緣區環境變化對全球尺度氣候變化周期的響應。

5豬野澤中全新世乾旱事件
季風邊緣區的湖泊沉積物中廣泛存在一次中全新世乾旱事件,但是關於這次事件的年代和機制還存在爭議。根據豬野澤湖泊沉積物的岩性、年代和待用指標探索,這次乾旱事件主要發生在~8.0-~7.0 cal kyr BP之間,其影響範圍主要在石羊河中、下游地區,對石羊河上游地區影響較小,這次乾旱事件可能主要受控於流域性水熱配比變化及季風與西風互動。

6豬野澤年代學
豬野澤湖泊沉積物晚第四紀年代結果主要來自孢粉濃縮物、全樣有機質、全樣無機質、軟體動物殼體AMS C和常規C測年,光釋光測年也應用於部分湖泊沉積剖面。通過多種物質的測年物質和測年方法結果對比,豬野澤晚第四紀湖泊沉積物碳庫效應較小,部分層位年代有倒置現象,年代混亂現象主要集中在晚冰期和早全新世地層中,這主要受湖泊再沉積作用影響。根據豬野澤東北岸古湖泊岸堤光釋光及C測年年代結果,豬野澤全新世高湖面期主要存在於早、中全新世,晚全新世體現了乾旱化趨勢。古湖泊岸堤年代結果所顯示的湖泊水位變化過程與湖泊沉積物指標研究一致。

7豬野澤孢粉
伴隨著流域性千年尺度環境變化和古生態-古植被變化,豬野澤沉積物孢粉記錄較好地反映了流域性植被的變化。但是豬野澤湖盆地形複雜,不同位置孢粉組合存在差異,湖盆西側受沖積相花粉影響較大,中、東部花粉組合較好的反映了湖泊水動力充分混合后的花粉組合。總體來講,早全新世上游喬木花粉含量較高,表現了較高的徑流量和降水量,中全新世花粉組合較豐富、孢粉濃度達到最高,晚全新世湖泊花粉組合變化現實了乾旱化趨勢。豬野澤地區全新世孢粉譜與其他指標對應較好,可靠地記錄了湖泊及流域的環境變化。

8豬野澤沉積物岩性、礦物及石英砂掃描電鏡分析
湖泊沉積物岩性、礦物及石英砂微形態也是反映湖泊演化過程的良好指標。豬野澤湖相沉積物以青灰色粉砂為主,部分層位夾雜褐色銹斑和黑色泥炭沉積層,湖相沉積層之間夾雜青灰色或黃褐色砂層,剖面頂部通常沉積了厚度不均的風成沉積物,這些岩性特徵指示了湖泊水動力條件的變化過程以及區域的風沙活動。碳酸鹽類礦物是該區域主要的鹽類礦物,其千年尺度鹽類礦物演化過程,體現了鹽湖演化的一般規律,與其他指標能形成良好對應。該區域沉積地層富含碳酸鹽類礦物,從而形成了一個巨大的無機碳庫。豬野澤地區砂層沉積物石英砂掃描電鏡分析揭示了該區域砂層沉積物來源的多元化,既帶有風成砂的特點,又經過水下環境的沉積,表明該區域砂層形成的複雜性。

9豬野澤沉積物地球化學
常用的湖泊沉積物有機地球化學指標有總有機碳(TOC)、碳氮比率(C/N)和有機碳同位素(δC)。它們可以反映湖泊及流域的初始生產力和植被類型,也反映了有機質隨沉積物沉積后的保存狀況,是湖泊及流域生態環境和古氣候、古環境變化信息的良好載體。豬野澤沉積物TOC與C/N變化趨勢一致,高值指示了較高的流域生產力,δC與其他兩種指標變化趨勢相反,其偏負指示較高的有效濕度。豬野澤沉積物地球化學指標研究結果與其他待用指標結果形成了良好對應,體現了早全新世徑流量及降水量較高,中全新世流域性初級生產力達到最大和晚全新世乾旱化的特點。

10豬野澤晚第四紀古湖泊地貌學
古湖泊岸堤高程測量和OSL及C測年可更好地了解中國西北地區晚第四紀高湖面的形成和演化。經實地調查表明,豬野澤東北緣有9級古湖泊岸堤和一級階地,這些古湖泊岸堤的年代結果體現了豬野澤從早、中全新世到晚全新世湖泊退縮的過程。全新世千年尺度上OSL及C測年雖然存在差異,但共同現實了早、中全新世的高湖面。MIS3和MIS5階段高湖面的情況,兩種方法結果存在差異,有待進一步研究。

11豬野澤水量平衡及GIS
千年尺度湖泊演化除了受大氣環流特徵的影響外,蒸發也起了重要作用。湖泊蒸發量主要與相對濕度、溫度、水汽壓和日照時間有關。根據豬野澤地區現代觀測結果,溫度和相對濕度的變化可能在全新世千年尺度湖泊水位的變化中起重要作用。進一步研究顯示,豬野澤湖泊水位變化受控因素較多,流域及湖面降水是最主要的控制因素,但是流域性蒸散發和湖面蒸發也會影響千年尺度湖泊面積變化。

12豬野澤及夏季風西北緣現代氣候過程
氣候變化的現代過程是研究古氣候變化的基礎。亞洲季風邊緣區受到季風與西風氣流的雙重影響,其古氣候變化體現出了一定的複雜性,通過該區域氣候現代過程的研究,短時間尺度上季風-西風相互作用明顯,而且這種短尺度的聯繫可以推測該區域長時間尺度氣候變化中兩大氣候系統的相互作用。

13季風邊緣區湖泊演化模擬
古氣候模擬與湖泊所記錄的古氣候信息提取是研究過去全球變化的兩種重要手段。模擬方法側重於古氣候變化機制研究,而湖泊記錄主要用於古氣候重建,將二者結合起來靈活運用是理解古氣候變化和長尺度水循環過程及機制的重要途徑。根據CCSM 3.0古氣候模式、湖泊水量&能量平衡模型結果,季風邊緣區末次盛冰期以來的湖泊演化過程與模擬結果匹配較好。豬野澤湖泊記錄是季風邊緣區的典型記錄,其與模擬結果匹配較好,模擬方法進一步解釋了豬野澤千年尺度演化的機制問題。
