| 1 | Definition of the core zone of the “westerlies-dominated climatic regime”, and its controlling factors during the instrumental period显示文摘The term 'westerlies-dominated climatic regime' describes the pattern of precipitation/moisture variations between westerliesdominated arid Central Asia(ACA) and mid-latitude monsoon-dominated Asia on decadal to multi-millennial time scales. However, no attempts have been made to define its core region and the possible physical mechanisms responsible during the period of instrumental observations. The present study investigates the spatiotemporal variations of summer and winter precipitation on interannual to decadal time scales over mid-latitudes of the Eurasian continent using Empirical Orthogonal Function(EOF) analysis. Our results suggest the existence of an opposing pattern of summer precipitation variations between ACA and mid-latitude monsoon-dominated Asia and Mediterranean on decadal time scales. Based on these results, the core region influenced by the westerlies is outlined, including arid central Asia and Xinjiang in China(36°–54°N, 50°–90°E). By using monthly NCEP-NCAR reanalysis, the relationship between the 'westerlies-dominated climatic regime' and atmospheric circulation were also analyzed. The combination of the zonal climatic teleconnection pattern and anomalous Indian Summer Monsoon Precipitation(ISMP) causes the precipitation characteristics of the 'westerlies-dominated climatic regime' precipitation pattern. In addition, the Atlantic Multidecadal Oscillation(AMO) may also have an important effect on the 'westerlies-dominated climatic regime'. | HUANG Wei CHEN JianHui ZHANG XiaoJian FENG Song CHEN FaHu | 2015 | Science China Earth Sciences2015，58，5： | 24 |
| 2 | 小冰期十年际尺度亚洲季风变化的四川黑竹沟洞石笋记录显示文摘基于四川省黑竹沟洞一支石笋(编号:EB1)高精度230Th年龄和氧同位素数据,建立小冰期时期(1375-1810A.D.)气候变化时间序列。该序列 δ^18O值变化范围为-10.37‰--8.58‰,敏感响应于区域气候变化过程。高分辨率 δ^18O变化序列能清晰地捕捉到10年际尺度振荡旋回。该石笋记录根据 δ^18O值变化可分为4个阶段:1375-1540A.D.和1680-1780A.D.时段, δ^18O值整体偏负,指示季风增强时期;1540-1680A.D.和1780-1810A.D.时段, δ^18O值整体偏正,处于弱季风阶段。与贵州董哥洞、甘肃万象洞和印度Jhumar洞石笋记录对比发现在小冰期时期 δ^18O变化特征具有一定的相似性,表明上述区域降水可能共同受控于印度季风水汽输送影响,反映了区域性夏季风经向环流及其降水变化特征。通过EB1石笋记录与北半球温度曲线的对比发现,两者在百年尺度上同相位变化,可能指示北高纬气候的控制作用。而该石笋与秘鲁东北部Cascayunga洞石笋记录的进一步对比结果显示亚洲季风与南半球季风记录呈反相位关系,证实了ITCZ位置的南北移动在半球间能量传递和交换过程中的重要作用。功率谱分析结果显示小冰期季风波动具有显著的25a和9a周期旋回,接近太阳黑子22a和11a周期频率,表明太阳活动变化可能是小冰期十年际尺度亚洲季风波动的重要驱动因素。 | 蒋文静 赵侃 陈仕涛 汪永进 程海 宁有丰 | 2017 | 第四纪研究2017，37，1： | 23 |
| 3 | 华北平原小冰期以来干湿变化与人类活动特征显示文摘气候变化尤其干湿变化对人类活动具有重要影响,高分辨率地重建过去的干湿变化是研究区域干湿变化的基础,同时也为未来气候变化提供依据。目前针对华北地区小冰期高分辨率的气候变化研究还较少,特别是干湿变化研究更少。本研究在3个AMS-14C测年的基础上,通过99个样品的孢粉、炭屑、粒度等指标高分辨率地重建了该地区小冰期以来的气候干湿变化特征及与人类活动强度的关系。结果表明:小冰期之前(约1340 A.D.)乔木花粉含量多在25%以上,指示流域植被以森林草地景观为主,沉积物颗粒较粗,沉积环境不稳定,气候较为湿润。小冰期期间(1340~1920 A.D.)乔木花粉多降低至15%以下,喜干的藜科、荨麻属和葎草属花粉含量明显增加,指示气候整体变干,但不同阶段变干程度又存在明显差异:小冰期早期(1340~1580 A.D.)孢粉组合中喜干的藜科花粉含量逐渐增加,湿生植物花粉含量减少,PCA axis 1得分值多在0~1之间,显示气候偏干。该时期与人类活动有关的炭屑浓度、农作物(禾本科≥35μm)花粉和磷(P)含量均最低,说明小冰期早期研究区人类活动强度相对较弱;小冰期中期(1580~1800 A.D.)喜干的藜科、荨麻属和葎草属花粉含量达到最高值,PCA axis 1得分值较小冰期早期更正偏,指示气候更为干旱。炭屑浓度、伴人植物、磷(P)含量和农作物(禾本科≥35μm)花粉均达最高值,指示人类活动强度明显增强;小冰期晚期(1800~1920 A.D.)湿生的禾本科和水生植物狐尾藻属等花粉含量达到最高值,PCA axis 1得分值负偏,指示气候变湿润。该阶段农作物(禾本科≥35μm)花粉、炭屑浓度和磷(P)含量较上一时期均略有降低,表明人类活动强度较小冰期中期略有降低。小冰期以后(1920年至今)喜湿的禾本科和水生植物狐尾藻属花粉含量减少,与小冰期晚期相比,气候向着干旱化方向发展. | 范保硕 张文胜 张茹春 阳小兰 李月丛 李冰 丁国强 | 2019 | 第四纪研究2019，39，2： | 21 |
| 4 | On the timing of the East Asian summer monsoon maximum during the Holocene Does the speleothem oxygen isotope record reflect monsoon rainfall variability?显示文摘The evolution of the East Asian summer monsoon(EASM) during the Holocene has long been of significant interest.Knowledge of past EASM variability not only increases our understanding of monsoon dynamics on a long timescale,but it also provides an environmental and climatic background for research into Chinese cultural development.However,the timing of the EASM maximum remains controversial.The popular concept of an 'early Holocene maximum' is mainly based on speleothemδ^(18)O(δ^(18)O_c) records from caves in southern China;however,the interpretation of δ^(18)O_C as a reliable proxy for EASM intensity is being increasingly challenged.The present paper is a critical review of the climatic significance of the δ^(18)O_C record from China.Firstly,we suggest that precipitation in northern China is an appropriate index of EASM intensity,the variation of which clearly indicates a mid-Holocene monsoon maximum.Secondly,an interregional comparison demonstrates that the precipitation record in northern China is quite different from that in southern China on a range of timescales,and is inconsistent with the spatial similarity exhibited by speleothem oxygen isotope records.Furthermore,both modeling and observational data show that the δ^(18)O_C records from southern China indeed reflect changes in precipitation δ^(18)O(δ^(18)O_P) rather than precipitation amount,and therefore that their use as an EASM proxy is inappropriate.Finally,we address several significant monsoon-related issues-including the driving mechanism of the EASM on an orbital timescale,the climatic significance of speleothem oxygen isotopes,and the relationship between atmospheric circulation and precipitation in monsoonal regions. | CHEN JianHui RAO ZhiGuo LIU JianBao HUANG Wei FENG Song DONG GuangHui HU Yu XU QingHai CHEN FaHu | 2016 | Science China(Information Sciences)2016，59，12： | 18 |

| 7 | Circulation background of climate patterns in the past millennium: Uncertainty analysis and re-reconstruction of ENSO-like state显示文摘The question of whether or not global warming has paused since more than ten years ago, namely 'warming hiatus', has attracted the attention of climate science community including the IPCC. Some authors have attributed the 'warming hiatus' to the internal changes in the climate system, i.e., the recombination of ocean-atmosphere circulations. Therefore, it is necessary to propose higher requirements on reconstructing circulation background of climate change for the past millennium. However, the analyses of changes in atmospheric circulation over the last millennium as well as the conclusions of related regional climate patterns are so widely different and contradictory, bringing uncertainties to our understanding of regional even global climate change to a great extent. On the other hand, in the last 10 years the high-precision U/Th-dated stalagmite oxygen isotope ratio(δ^(18)O) sequences provided an accurate chronological frame for the paleoclimate study of the middle and late Pleistocene, in which all authors from China took the Chinese stalagmite δ^(18)O as the summer monsoon index without exception. However, this point of view misleads the climate scientists into thinking that the stalagmite δ^(18)O can be as the proxy of precipitation amount. Nevertheless, it is well known that all of these records have a lot in common in the low frequency trend. However, most sequences cannot be calibrated by instrumental precipitation records, and thus the uncertainty of the climate research framework of China and even of the world has increased. Therefore, it is imperative for climatology to clarify the origin of contradiction and to reduce the uncertainty as early as possible. On the basis of analyzing the significance of stalagmite δ^(18)O in the monsoon regions of China, the author tries to propose a new circulation proxy in this paper: integrating the Chinese stalagmite oxygen isotope sequence to reconstruct the tropical Pacific sea surface temperature gradient, i.e., the large-scale ENSO-like state over the past millennium. Furthermore, the author speculates that it was warm in the modern times and the Medieval Period, but the circulation recombination was different in both periods. And this inference could be supported by the longer record since Last Glacial Maximum. In other words, the attribution analysis of the identical low-frequency trends of Chinese stalagmite δ^(18)O on a large scale shows that the ENSO-like state controls the climate change in the monsoon regions of China at different time scales(from interannual to century or even longer time scales). Wherein the important connection of circulations is the western Pacific subtropical high(WPSH), that is to say, besides the interannual and decadal time scales, the WPSH would possess the circulation mode on longer timescales. For example, we may discuss the change of the WPSH in the whole Holocene epoch, i.e., the half precession period. These discussions could make sense to the study of not only the paleoclimate but also the modern climate. | TAN Ming | 2016 | Science China Earth Sciences2016，59，6： | 16 |
| 8 | 晚全新世以来福建仙山泥炭钻孔的正构烷烃记录显示文摘通过对福建仙山泥炭钻孔中正构烷烃的分析,探讨了研究区近千年以来的气候特征。分析显示:正构烷烃分布范围主要为C16~C35,且以奇碳链为主,奇偶优势明显。正构烷烃与有机质含量(TOC)密切相关,在典型的泥炭层,TOC含量高,长碳链的C27,C29和C31正构烷烃占优势,揭示有机质主要来源于草本或木本等高等植物,盆地处于相对干的沉积环境;在非泥炭层,TOC含量低,钻孔中多含粗砂或粉砂,中碳链的C21或C23正构烷烃占优势,揭示有机质主要来源于水生植物或苔藓植物,表明相对较湿的沉积环境。钻孔中正构烷烃C23/C27比值与前人提出的C23/C29和P等参数呈同向变化,可以作为区域干一湿变化的代用指标。结合地层的年代序列,利用正构烷烃重建了区域距今1400年以来的植被演化和气候变化历史。结果显示,福建仙山地区气候存在3次相对湿润和4次相对较干的时段。在钻孔358—280cm(约公元600—910年),气候相对较干,在280~40cm(约公元910~1640年),降水较多,气候湿润,但中间存在两次变干的阶段;在40-0cm(约公元1640年至今),降水相对较少,气候转干。TOC含量和正构烷烃C23/C27序列与南方旱涝频率序列、石笋和硅藻记录对比显示,研究区在中世纪暖期气候相对较干,而小冰期则相对湿润,揭示出仙山泥炭沉积记录的气候信息具有区域一致性,为认识季风在短时间尺度的变化特征提供了依据。 | 朱芸 雷国良 姜修洋 李志忠 靳建辉 | 2013 | 第四纪研究2013，33，6： | 13 |
| 9 | 洞庭湖区旱涝灾害加剧的气象成因显示文摘利用洞庭湖区及湖南四水流域、长江上游地区气象观测资料和各类指标资料,基于统计方法,开展洞庭湖区旱涝加剧气象成因分析,得出如下结论:我国主雨带位置的年代际变化直接影响到洞庭湖区雨水资源的丰枯变化,进而影响到旱涝趋势的变化;东亚夏季风和赤道中东太平洋地区海表温度异常通过对我国主雨带位置的影响来影响洞庭湖区水资源的丰枯;气候变暖背景下洞庭湖各流域雨水资源向丰枯同步转变,易使洞庭湖洪水形成顶托之势或水资源来源枯竭,导致旱涝灾害加重;洞庭湖各流域枯水季节雨水资源减少加重洞庭湖区枯水季节缺水程度。 | 廖玉芳 赵辉 彭嘉栋 吴贤云 张剑明 段丽洁 | 2016 | 灾害学2016，31，1： | 13 |
| 10 | Global Climate Internal Variability in a 2000-year Control Simulation with Community Earth System Model(CESM)显示文摘Using the low-resolution(T31, equivalent to 3.75°× 3.75°) version of the Community Earth System Model(CESM) from the National Center for Atmospheric Research(NCAR), a global climate simulation was carried out with fixed external forcing factors(1850 Common Era.(C.E.) conditions) for the past 2000 years. Based on the simulated results, spatio-temporal structures of surface air temperature, precipitation and internal variability, such as the El Nio-Southern Oscillation(ENSO), the Atlantic Multi-decadal Oscillation(AMO), the Pacific Decadal Oscillation(PDO), and the North Atlantic Oscillation(NAO), were compared with reanalysis datasets to evaluate the model performance. The results are as follows: 1) CESM showed a good performance in the long-term simulation and no significant climate drift over the past 2000 years; 2) climatological patterns of global and regional climate changes simulated by the CESM were reasonable compared with the reanalysis datasets; and 3) the CESM simulated internal natural variability of the climate system performs very well. The model not only reproduced the periodicity of ENSO, AMO and PDO events but also the 3–8 years variability of the ENSO. The spatial distribution of the CESM-simulated NAO was also similar to the observed. However, because of weaker total irradiation and greenhouse gas concentration forcing in the simulation than the present, the model performances had some differences from the observations. Generally, the CESM showed a good performance in simulating the global climate and internal natural variability of the climate system. This paves the way for other forced climate simulations for the past 2000 years by using the CESM. | WANG Zhiyuan LI Yao LIU Bin LIU Jian | 2015 | Chinese Geographical Science2015，25，3： | 13 |
| 11 | Paleoclimate Modeling in China: A Review显示文摘This paper provides a review of paleoclimate modeling activities in China. Rather than attempt to cover all topics, we have chosen a few climatic intervals and events judged to be particularly informative to the international community. In historical climate simulations, changes in solar radiation and volcanic activity explain most parts of reconstructions over the last millennium prior to the industrial era, while atmospheric greenhouse gas concentrations play the most important role in the20 th century warming over China. There is a considerable model–data mismatch in the annual and boreal winter temperature change over China during the mid-Holocene [6000 years before present(ka BP)], while coupled models with an interactive ocean generally perform better than atmospheric models. For the Last Glacial Maximum(21 ka BP), climate models successfully reproduce the surface cooling trend over China but fail to reproduce its magnitude, with a better performance for coupled models. At that time, reconstructed vegetation and western Pacific sea surface temperatures could have significantly affected the East Asian climate, and environmental conditions on the Qinghai–Tibetan Plateau were most likely very different to the present day. During the late Marine Isotope Stage 3(30–40 ka BP), orbital forcing and Northern Hemisphere glaciation, as well as vegetation change in China, were likely responsible for East Asian climate change. On the tectonic scale,the Qinghai–Tibetan Plateau uplift, the Tethys Sea retreat, and the South China Sea expansion played important roles in the formation of the East Asian monsoon-dominant environment pattern during the late Cenozoic. | JIANG Dabang YU Ge ZHAO Ping CHEN Xing LIU Jian LIU Xiaodong WANG Shaowu ZHANG Zhongshi YU Yongqiang LI Yuefeng JIN Liya XU Ying JU Lixia ZHOU Tianjun YAN Xiaodong | 2015 | Advances in Atmospheric Sciences2015，32，2： | 12 |
| 12 | 过去2000年亚洲夏季风降水百年尺度变化及其区域差异的模拟分析显示文摘摘要利用通用地球系统模式(CESM,1.0.3版本)进行的多个过去2000年瞬变积分试验模拟结果,初步探讨了亚洲夏季风及其子系统(东亚夏季风、印度夏季风和西北太平洋夏季风)降水百年尺度时卒变化特征与成因。研究表明:1)亚洲季风区及其子区降水与温度的时间变化均基本同位相。亚洲夏季风降水存在准100年、准150年和准200年周期,东亚夏季风降水存在准200年和准100年周期,印度和西北太平洋夏季风降水均存在准100年的显著周期;太阳辐射是影响各区域夏季风降水百年际周期的主要因素,东亚和亚洲夏季风降水百年际周期还与火山活动有关。2)亚洲夏季风降水标准化EOF第一模态的空间分布型为100。E以东由北向南早“正-负-正-负”的条带状分布和在100°E以西的印度季风区呈西南一东北向的“正-负-正”分布,该分布型主要受太阳辐射的影响;EOF第二模态呈现阿拉伯海东部、印度半岛南端和华北平原及其以东同纬地区与其他地方反相的分布型态,该分布型主要受温窀气体和气候系统内部变率的共同影响;分析表明多因子问的非线性相瓦作用会放大对气候系统内部变率的影响。3)亚洲夏季风3个子系统降水百年尺度第一模态空间分布与亚洲夏季风降水第一模态中对应区域的分布型态相似;东亚夏季风降水主模态主要受太阳辐射和温室气体的共同影响,印度夏季风降水主模态与太阳辐射有关,西北太平洋夏季风降水主模态受除火山活动外的多因子共同影响。 | 韩春凤 刘健 王志远 | 2016 | 第四纪研究2016，36，3： | 12 |
| 13 | 地球系统模式CESM1.0对太阳辐射和温室气体的敏感性差异研究显示文摘利用通用地球系统模式CESM1.0的全强迫试验和单因子敏感性试验结果,初步探讨了CESM模拟的地表气温、降水率对太阳辐射和温室气体的敏感性差异,以便更好地认识自然和人为因子对全球气候变化的贡献。结果表明:地球系统模式CESM1.0对温室气体变化的敏感性比对太阳辐射的敏感性高,温室气体含量变化引起相当于1W/m2的辐射强迫增加会导致全球平均温度上升0.51℃,而太阳辐射变化1W/m。时全球平均温度仅上升0.27%;在太阳辐射单因子敏感性试验中,地表气温每升高1qc降水量增加2.91%,要高于温室气体单因子敏感性试验的增量2.22%。另外,自然和人为因子所导致的地表气温空间变化特征也不相同,在太阳活动影响下,气温首先在北欧区域明显升高,赤道西太平洋暖池区域随着总太阳辐射量的增加而明显变暖,但在白令海峡和格陵兰岛区域则出现明显降温;而在温室气体影响下,地表气温则在北半球高纬区域显著增加,赤道东太平洋区域随着温室气体浓度的增加呈现出类似El Nifio的分布型态。 | 王志远 刘健 王晓青 刘斌 | 2016 | 第四纪研究2016，36，3： | 8 |
| 14 | 轨道尺度东亚夏季风的动力反演显示文摘为了探求太阳辐射和高纬地区温度对东亚夏季风的驱动机理,用动力反演的方法建立了东亚夏季风的动力方程,为东亚夏季风的驱动机制研究提供了一种新的方法。在轨道尺度上得到如下结论:东亚夏季风是由南极温度和太阳辐射量共同驱动的复杂非线性动力系统;太阳辐射是驱动东亚夏季风的最重要驱动力,驱动贡献至少达到67.57%,南极温度次之,其驱动贡献达到21.58%,格陵兰温度对东亚夏季风的驱动不起作用;太阳辐射量的增加,会驱使东亚夏季风增强;南极温度存在一个阈值,在阈值两侧,对东亚夏季风具有不同的驱动机制;东亚夏季风对太阳辐射驱动的响应,还部分地依赖于季风强度的背景值。 | 罗虎明 林振山 李玉霞 | 2013 | 第四纪研究2013，33，3： | 8 |
| 15 | The FGOALS climate system model as a modeling tool for supporting climate sciences:An overview显示文摘Climate system models are useful tools for understanding the interactions among the components of the climate system and predicting/projecting future climate change. The development of climate models has been a central focus of the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of Atmospheric Physics, Chinese Academy of Sciences(LASG/IAP) since the establishment of the laboratory in 1985. In China, many pioneering component models and fully coupled models of the climate system have been developed by LASG/IAP. The fully coupled climate system developed in the recent decade is named FGOALS(Flexible Global Ocean-Atmosphere-Land System Model). In this paper, an application-oriented review of the LASG/IAP FGOALS model is presented. The improved model performances are demonstrated in the context of cloud-radiation processes, Asian monsoon, ENSO phenomena, Atlantic Meridional Overturning Circulation(AMOC) and sea ice. The FGOALS model has contributed to both CMIP5(Coupled Model Intercomparison Project-phase 5) and IPCC(Intergovernmental Panel on Climate Change) AR5(the Fifth Assessment Report). The release of FGOALS data has supported the publication of nearly 500 papers around the world. The results of FGOALS are cited ~106 times in the IPCC WG1(Working Group 1) AR5. In addition to the traditional long-term simulations and projections, near-term decadal climate prediction is a new set of CMIP experiment, progress of LAGS/IAP in the development of nearterm decadal prediction system is reviewed. The FGOALS model has supported many Chinese national-level research projects and contributed to the national climate change assessment report. The crucial role of FGOALS as a modeling tool for supporting climate sciences is highlighted by demonstrating the model's performances in the simulation of the evolution of Earth's climate from the past to the future. | TianJun Zhou Bin Wang YongQiang Yu YiMin Liu WeiPeng Zheng LiJuan Li Bo Wu PengFei Lin Zhun Guo WenMin Man Qing Bao AnMin Duan HaiLong Liu XiaoLong Chen Bian He JianDong Li LiWei Zou XiaoCong Wang LiXia Zhang Yong Sun WenXia Zhang | 2018 | Earth and Planetary Physics2018，2，4： | 6 |
| 16 | 甘肃合水地区全新世以来土壤剖面黑碳记录及其气候变化显示文摘针对甘肃合水马家村(MJC)全新世黄土剖面进行野外采样,分析磁化率和黑碳(焦炭和烟炱)等古气候指标,试图探讨黄土高原北部全新世以来生物质燃烧特征以及自然生态环境演变过程,结果表明:末次冰期和全新世早期(11500—8500 a BP)气候寒冷而干旱,区域野火事件时而发生,植被生物量是此阶段野火发生与蔓延的限制因素;距今8000年以来,黑碳和炭屑浓度整体呈现下降趋势。由于季节性降水增多从而抑制大范围火灾发生几率。然而,8000—7000 a BP和3500—2500 a BP野火频率明显上升,这可能与仰韶时期老官台文化和寺洼文化时期的古人类放火烧荒和开垦农田等活动有关;全新世晚期(3100 a BP至今)气候进一步干旱,生物质燃烧增强与人口增加和人类土地利用水平密切相关,其中1500—1000 a BP出现一次较为明显的峰值,这可能与隋唐以来该区农耕活动加强有关。可见,近2000年以来黄土高原北部地区生物质燃烧特征受到气候和人类活动复合驱动所控制。 | 廖冰 谭志海 孙斌 龙艳侠 范汇晨 刘钊 | 2017 | 地球环境学报2017，8，1： | 4 |

| 18 | Coastal environment of the past millennium recorded by a coastal dune in Fujian,China显示文摘Coastal dune is a common aeolian geomorphology in a sandy coast,which records the evolution process of the aeolian landscape system and reflects the complex interaction among land surface,atmosphere and ocean.Coast is a sensitive area to global climate change.Restricted by chronology,most previous researches in China focused only on the cause of formation of coastal dunes.In recent years,the development of optically stimulated luminescence (OSL) dating provides a good method and acts as a carrier for coastal dunes to paleoclimate and paleoenvironmental studies.In this study,we selected an aeolian dune at the Anshan archaeological site,Fujian,China as the research object based on field observations.For determining their sedimentary stages and the primary influencing factors,we used the OSL dating method to construct a chronological framework for the aeolian dune.In addition,the sizes of grains were analyzed for identifying factors influencing the winter monsoon during the Medieval Warm Period (MWP) and the Little Ice Age (LIA) in this area.The results showed that the deposition of the aeolian dune was closely related to variations in the winter monsoon intensity.The changes of the winter monsoon were similar to the tendency of the East Asian winter monsoon,although there were several sub-fluctuations.From an overall perspective,the winter monsoon was strengthened during the MWP (1050–1300) .The results of a power spectrum analysis showed that the intensity of the East Asian winter monsoon is correlated with sunspot activity. | JIN Jianhui LI Zhizhong JIANG Feng deng tao HU Fan'gen LING Zhiyong | 2016 | Journal of Arid Land2016，8，5： | 3 |
| 19 | 中国中世纪暖期气候变化的基本特征显示文摘对中世纪暖期(MWP)的时空分异和区域影响进行综合分析,关系到对近百年来全球气候变暖驱动力的正确认识,也有助于客观地解析20世纪气候变化增暖的历史地位.本研究对中国疆域内各个地区MWP的一些成果进行梳理和再思考,表明MWP在中国疆域内的存在是毋庸置疑的,但不同地区MWP表现出明显的时空差异.中国中东部地区在800—1300 AD存在明显温暖期,各种地质记录和文献记载都有较明显反映;虽然西北部MWP表现不很明显,但是众多石笋、湖泊沉积和风沙沉积也记录了500—1500 AD间呈现温暖湿润的气候特征;青藏高原各地MWP的表现差异明显,其中800—1100 AD暖期是高原东北部最暖的时期,而南部和西部最暖期分别出现于1150—1400 AD和1250—1500 AD.太阳辐射变化和火山活动可能是形成MWP的基本原因,而中国三大自然区下垫面条件的复杂多样性造成MWP发生过程和表现形式的时空分异. | 陈秀玲 刘秀铭 李志忠 姜修洋 雷国良 朱芸 靳建辉 | 2012 | 亚热带资源与环境学报2012，7，1： | 3 |
| 20 | 东亚季风区最近1000 a石笋δ^(18)O空间变化特征及气候意义研究显示文摘利用重庆市丰都水鸣洞石笋NSM03精确定年数据和δ^(18)O数据建立的高分辨率石笋记录,结合其他已经发表的亚洲季风区石笋氧同位素记录,探讨洞穴石笋δ^(18)O值过去1000 a的空间变化特征以及指示的气候环境意义.结果显示:亚洲季风区石笋δ^(18)O值过去1000 a在空间上呈现出与大气降水δ^(18)O值相似的纬度效应和海陆效应,石笋δ^(18)O值沿水汽输送路径不断衰减,逐渐变轻,表明印度洋是中国季风降水的主要水汽源区;水鸣洞NSM03石笋记录与南亚季风区瓦什卡洞的WBS石笋记录以及中国藏南波密-林芝地区的树轮记录存在明显的相关关系,也进一步地表明中国东部季风区的水汽主要来自印度洋;亚洲季风区石笋δ^(18)O记录在过去1000 a的变化趋势基本一致,但是中国东部季风区降水变化存在很大的空间差异,这表明季风区石笋δ^(18)O记录不一定都能指示当地降水量的变化;因此,中国季风区石笋δ^(18)O记录主要指示是东亚季风环流的信息,当东亚季风环流强的时候,季风区石笋氧同倍数偏轻;反之亦然. | 鄢应燃 刘睿恺 杨勋林 吕春艳 张日萍 张瑞 | 2021 | 西南师范大学学报(自然科学版)2021，46，4： | 2 |
