研究成果
根據(jù)現(xiàn)代氣候?qū)W研究,亞洲夏季風(fēng)的水汽輸送西北邊界位于青藏高原東北部的柴達(dá)木盆地、祁連山及河西走廊中東部地區(qū),該區(qū)域處于戈壁大漠和高原之間的過渡地帶,其現(xiàn)代氣候過程受到亞洲季風(fēng)和西風(fēng)帶氣流的雙重影響,千-百年尺度氣候變化過程復(fù)雜,在長時間尺度上,該區(qū)域的氣候變化和湖泊演化對季風(fēng)系統(tǒng)和西風(fēng)帶環(huán)流的響應(yīng)與機(jī)制是過去全球變化研究中一個重要的科學(xué)問題。李育的研究方向是夏季風(fēng)西北緣長時間尺度環(huán)境變化、冬夏季風(fēng)演化和湖泊演化及其機(jī)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(chuàng)新點(diǎn)包括:(1)在東、中亞地區(qū)使用古氣候模式和湖泊模型,模擬了長時間尺度冬、夏季風(fēng)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(fēng)對季風(fēng)邊緣區(qū)的影響;(3)將該區(qū)域現(xiàn)代氣候過程方法運(yùn)用于古氣候?qū)W研究,并結(jié)合古氣候模擬證實了湖泊表面蒸發(fā)對千年尺度湖泊演化的影響。
(1)季風(fēng)邊緣區(qū)長尺度冬夏季風(fēng)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(cè)重于古氣候變化機(jī)制研究,而湖泊記錄主要用于古氣候重建,將二者結(jié)合起來靈活運(yùn)用是理解古氣候變化和長尺度水循環(huán)過程及機(jī)制的重要途徑。
我國冬季極端寒冷事件和冰凍災(zāi)害與亞洲冬季風(fēng)的突變有密切聯(lián)系,探索長時間尺度東亞冬季風(fēng)變化機(jī)制,有助于理解和預(yù)測全球變暖背景下冬季風(fēng)變化趨勢。我國之前研究已獲取大量冬季風(fēng)重建的結(jié)果,但是這些結(jié)果存在差異且很少涉及冬季風(fēng)演化機(jī)制。李育研究組使用the Community Climate System Model version 3 (CCSM3)耦合氣候模式,并采用連續(xù)氣候模擬方法,連續(xù)模擬了全新世期間東亞冬季風(fēng)的演化序列,在此基礎(chǔ)上對比了模擬冬季風(fēng)強(qiáng)度與戈壁沙漠南緣的全新世風(fēng)成沉積記錄,二者具有較好一致性,進(jìn)一步證實了該項模擬的可靠性。氣候模擬結(jié)果所揭示的全新世氣候變化機(jī)制表明:軌道參數(shù)所驅(qū)動的海、陸溫度及氣壓差異是全新世亞洲冬季風(fēng)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(fēng)較強(qiáng)的重要因素。在現(xiàn)代全球變暖背景下,軌道參數(shù)和正在消融的北半球高緯度冰川本應(yīng)伴隨較弱的冬季風(fēng)強(qiáng)度,但是近10年來北半球冬季極端低溫事件頻發(fā),可能與人類活動有關(guān)。
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(jié)合的方式,在東、中亞地區(qū)模擬了LGM、早、中、晚全新世湖泊水位變化的過程,并將模擬結(jié)果與該區(qū)的湖泊水位重建結(jié)果進(jìn)行了對比,二者顯示了一致性,在此基礎(chǔ)上討論了東亞季風(fēng)區(qū)和中亞干旱區(qū)全新世湖泊水位演化的差異及其機(jī)理。這項研究為理解季風(fēng)邊緣區(qū)湖泊水循環(huán)變化過程做出了重要貢獻(xiàn)。研究成果發(fā)表于《Climate Dynamics》(一區(qū))、《Quaternary Science Reviews》(一區(qū))、《Global and Planetary Change》(二區(qū))等國際權(quán)威雜志。
(2)河西走廊古湖泊學(xué)研究
石羊河流域位于青藏高原東北緣、河西走廊東段地區(qū),處于我國三大自然區(qū)(東部季風(fēng)區(qū)、西北干旱區(qū)和青藏高原區(qū))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,對于理解三大自然區(qū)過渡地帶的氣候變化過程及機(jī)理有重要作用。前人在該區(qū)域展開了大量研究,但是關(guān)于全新世中期的氣候及環(huán)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,并結(jié)合孢粉濃縮物測年和其他年代學(xué)結(jié)果對比的方法,推進(jìn)了豬野澤千年尺度環(huán)境變化研究。結(jié)果顯示:豬野澤地區(qū)早全新世環(huán)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(huán)境趨于干旱。中全新世期間存在一次百年尺度的干旱事件,不同位置的沉積剖面的砂層沉積是這次干旱事件的主要標(biāo)志物。豬野澤全新世環(huán)境變化主要受亞洲夏季風(fēng)演化控制,同時也受到中緯度西風(fēng)帶氣候變化的影響,體現(xiàn)了季風(fēng)邊緣區(qū)湖泊演化的特殊性。主要成果發(fā)表于《Boreas》、《Palaeogeography, Palaeoclimatology, Palaeoecolog》、《中國科學(xué)》和《科學(xué)通報》等著名期刊。
鹽池位于河西走廊中段,是現(xiàn)代亞洲夏季風(fēng)水汽輸送可到達(dá)的邊界區(qū)域。李育等使用孢粉濃縮物測年、礦物分析、地球化學(xué)指標(biāo)等方法研究了鹽池晚冰期以來湖泊沉積物,結(jié)果顯示:鹽池晚冰期以來湖泊演化過程與青藏高原區(qū)和典型季風(fēng)區(qū)的古氣候記錄具有一致性,晚冰期及早全新世湖泊擴(kuò)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(fēng)對該區(qū)域的影響,證明了夏季風(fēng)北部邊界擺動的事實。主要成果發(fā)表于《Palaeogeography, Palaeoclimatology, Palaeoecology》和《地理學(xué)報》等著名期刊。
(3)干旱、半干旱區(qū)湖泊水循環(huán)的現(xiàn)代過程研究
氣候變化的現(xiàn)代過程是研究古氣候變化的基礎(chǔ)。亞洲季風(fēng)邊緣區(qū)受到季風(fēng)與西風(fēng)氣流的雙重影響,其古氣候變化體現(xiàn)出了一定的復(fù)雜性。為探索季風(fēng)邊緣區(qū)古氣候變化的機(jī)制,李育等通過季風(fēng)邊緣區(qū)現(xiàn)代降水和過程研究,進(jìn)一步探討了該區(qū)域氣候變化與兩大氣候系統(tǒng)的聯(lián)系,并通過現(xiàn)代過程的研究得出該區(qū)長尺度氣候變化也可能受到兩大氣候系統(tǒng)相互作用的影響。
同時,蒸發(fā)作用是湖泊水循環(huán)的重要環(huán)節(jié),以往的長尺度湖泊演化研究中,蒸發(fā)作用影響僅被停留在討論之中。為了更加準(zhǔn)確地了解蒸發(fā)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(qū)的現(xiàn)代蒸發(fā)資料,發(fā)現(xiàn)這兩個湖泊現(xiàn)代蒸發(fā)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(fā)表于《地理學(xué)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(jì)文獻(xiàn)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于青藏高原北緣的祁連山南麓,處于戈壁大漠和高原之間的過渡地帶。在氣候上,該區(qū)域處于亞洲夏季風(fēng)的西北緣,部分夏季降水來源于夏季風(fēng)水汽輸送,同時主要受控于中緯度西風(fēng)帶環(huán)流,是季風(fēng)-西風(fēng)相互作用的關(guān)鍵區(qū)域。近年來,該區(qū)域晚第四紀(jì)環(huán)境變化研究取得了大量進(jìn)展,推動了長時間尺度季風(fēng)和西風(fēng)演化的研究,但還存在一些爭議。一個主要問題就是該區(qū)域文獻(xiàn)量比較大,與第四紀(jì)相關(guān)的論文較多,且學(xué)科較雜,不利于相關(guān)學(xué)者了解該區(qū)域的研究狀況。本索引旨在整理該區(qū)域近年來各相關(guān)學(xué)科的主要文獻(xiàn),便于第四紀(jì)科學(xué)研究者了解該區(qū)域狀況,同時該索引也代表了蘭州大學(xué)晚第四紀(jì)研究在該區(qū)域的進(jìn)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(huán)境變化
豬野澤湖泊沉積物環(huán)境代用指標(biāo)記錄顯示,豬野澤地區(qū)早全新世環(huán)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(huán)境趨于干旱。中全新世期間存在一次百年尺度的干旱事件,不同位置的沉積剖面的砂層沉積是這次干旱事件的主要標(biāo)志物。豬野澤全新世環(huán)境變化主要受亞洲夏季風(fēng)演化控制,同時也受到中緯度西風(fēng)帶氣候變化的影響,體現(xiàn)了季風(fēng)邊緣區(qū)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(qū)和典型季風(fēng)區(qū)的古氣候記錄具有一致性,晚冰期及早全新世湖泊擴(kuò)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(fēng)對該區(qū)域的影響,證明了夏季風(fēng)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(huán)境變化表現(xiàn)為,早全新世環(huán)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(huán)境趨于干旱。這種水分條件的變化與早全新世較強(qiáng)的亞洲季風(fēng)所帶來的較多降水有關(guān),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(fēng)帶的影響。

4豬野澤氣候變化周期
豬野澤湖泊沉積物古環(huán)境代用指標(biāo)記錄顯示,該區(qū)域有明顯的~256、~512、~1024年氣候循環(huán)周期,這與典型亞洲夏季風(fēng)區(qū)全新世千年尺度和百年尺度氣候循環(huán)周期一致。同時,該區(qū)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(guān),體現(xiàn)了季風(fēng)邊緣區(qū)環(huán)境變化對全球尺度氣候變化周期的響應(yīng)。

5豬野澤中全新世干旱事件
季風(fēng)邊緣區(qū)的湖泊沉積物中廣泛存在一次中全新世干旱事件,但是關(guān)于這次事件的年代和機(jī)制還存在爭議。根據(jù)豬野澤湖泊沉積物的巖性、年代和待用指標(biāo)探索,這次干旱事件主要發(fā)生在~8.0-~7.0 cal kyr BP之間,其影響范圍主要在石羊河中、下游地區(qū),對石羊河上游地區(qū)影響較小,這次干旱事件可能主要受控于流域性水熱配比變化及季風(fēng)與西風(fēng)互動。

6豬野澤年代學(xué)
豬野澤湖泊沉積物晚第四紀(jì)年代結(jié)果主要來自孢粉濃縮物、全樣有機(jī)質(zhì)、全樣無機(jī)質(zhì)、軟體動物殼體AMS C和常規(guī)C測年,光釋光測年也應(yīng)用于部分湖泊沉積剖面。通過多種物質(zhì)的測年物質(zhì)和測年方法結(jié)果對比,豬野澤晚第四紀(jì)湖泊沉積物碳庫效應(yīng)較小,部分層位年代有倒置現(xiàn)象,年代混亂現(xiàn)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(jù)豬野澤東北岸古湖泊岸堤光釋光及C測年年代結(jié)果,豬野澤全新世高湖面期主要存在于早、中全新世,晚全新世體現(xiàn)了干旱化趨勢。古湖泊岸堤年代結(jié)果所顯示的湖泊水位變化過程與湖泊沉積物指標(biāo)研究一致。

7豬野澤孢粉
伴隨著流域性千年尺度環(huán)境變化和古生態(tài)-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復(fù)雜,不同位置孢粉組合存在差異,湖盆西側(cè)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?傮w來講,早全新世上游喬木花粉含量較高,表現(xiàn)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(dá)到最高,晚全新世湖泊花粉組合變化現(xiàn)實了干旱化趨勢。豬野澤地區(qū)全新世孢粉譜與其他指標(biāo)對應(yīng)較好,可靠地記錄了湖泊及流域的環(huán)境變化。

8豬野澤沉積物巖性、礦物及石英砂掃描電鏡分析
湖泊沉積物巖性、礦物及石英砂微形態(tài)也是反映湖泊演化過程的良好指標(biāo)。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(fēng)成沉積物,這些巖性特征指示了湖泊水動力條件的變化過程以及區(qū)域的風(fēng)沙活動。碳酸鹽類礦物是該區(qū)域主要的鹽類礦物,其千年尺度鹽類礦物演化過程,體現(xiàn)了鹽湖演化的一般規(guī)律,與其他指標(biāo)能形成良好對應(yīng)。該區(qū)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(jī)碳庫。豬野澤地區(qū)砂層沉積物石英砂掃描電鏡分析揭示了該區(qū)域砂層沉積物來源的多元化,既帶有風(fēng)成砂的特點(diǎn),又經(jīng)過水下環(huán)境的沉積,表明該區(qū)域砂層形成的復(fù)雜性。

9豬野澤沉積物地球化學(xué)
常用的湖泊沉積物有機(jī)地球化學(xué)指標(biāo)有總有機(jī)碳(TOC)、碳氮比率(C/N)和有機(jī)碳同位素(δCorg)。它們可以反映湖泊及流域的初始生產(chǎn)力和植被類型,也反映了有機(jī)質(zhì)隨沉積物沉積后的保存狀況,是湖泊及流域生態(tài)環(huán)境和古氣候、古環(huán)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(chǎn)力,δCorg與其他兩種指標(biāo)變化趨勢相反,其偏負(fù)指示較高的有效濕度。豬野澤沉積物地球化學(xué)指標(biāo)研究結(jié)果與其他待用指標(biāo)結(jié)果形成了良好對應(yīng),體現(xiàn)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(chǎn)力達(dá)到最大和晚全新世干旱化的特點(diǎn)。

10豬野澤晚第四紀(jì)古湖泊地貌學(xué)
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(qū)晚第四紀(jì)高湖面的形成和演化。經(jīng)實地調(diào)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(jié)果體現(xiàn)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(xiàn)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(jié)果存在差異,有待進(jìn)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(huán)流特征的影響外,蒸發(fā)也起了重要作用。湖泊蒸發(fā)量主要與相對濕度、溫度、水汽壓和日照時間有關(guān)。根據(jù)豬野澤地區(qū)現(xiàn)代觀測結(jié)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(jìn)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(fā)和湖面蒸發(fā)也會影響千年尺度湖泊面積變化。

12豬野澤及夏季風(fēng)西北緣現(xiàn)代氣候過程
氣候變化的現(xiàn)代過程是研究古氣候變化的基礎(chǔ)。亞洲季風(fēng)邊緣區(qū)受到季風(fēng)與西風(fēng)氣流的雙重影響,其古氣候變化體現(xiàn)出了一定的復(fù)雜性,通過該區(qū)域氣候現(xiàn)代過程的研究,短時間尺度上季風(fēng)-西風(fēng)相互作用明顯,而且這種短尺度的聯(lián)系可以推測該區(qū)域長時間尺度氣候變化中兩大氣候系統(tǒng)的相互作用。

13季風(fēng)邊緣區(qū)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(cè)重于古氣候變化機(jī)制研究,而湖泊記錄主要用于古氣候重建,將二者結(jié)合起來靈活運(yùn)用是理解古氣候變化和長尺度水循環(huán)過程及機(jī)制的重要途徑。根據(jù)CCSM 3.0古氣候模式、湖泊水量&能量平衡模型結(jié)果,季風(fēng)邊緣區(qū)末次盛冰期以來的湖泊演化過程與模擬結(jié)果匹配較好。豬野澤湖泊記錄是季風(fēng)邊緣區(qū)的典型記錄,其與模擬結(jié)果匹配較好,模擬方法進(jìn)一步解釋了豬野澤千年尺度演化的機(jī)制問題。
