关于现代智人起源的争论一直是国际古人类学研究的前沿与热点.最近,在广西崇左木榄山智人洞发现了具有现代人解剖特征初始状态的人类下颌骨化石及大量与之共生的哺乳动物化石.木榄山智人洞哺乳动物群以江南象与初现的亚洲象及巨獏等组合为其特征,截然不同于华南早更新世的巨猿动物群和中更新世的大熊猫-剑齿象动物群,是典型亚洲象动物群的早期代表.依动物群性质、地层对比及铀系年代测定木榄山化石智人和伴生的哺乳动物群的时代为距今约11万年的晚更新世早期.该动物群主要由热带-亚热带型动物组成,但木榄山动物群中森林型动物种类单调,草地类型的动物相当多,这表明当时的气候可能比以前干燥.木榄山智人的发现对研究现代人起源及其环境背景具有非常重要的意义.

研究石漠化扩张的机制,有利于岩溶地区人与自然的可持续发展.中国西南大面积的石漠化是受气候变化还是人类活动的主导仍然存在争议.通过贵州省石将军洞高精度的石笋δ^(13)C记录,本研究重建了过去2000年来中国西南区域的石漠化演变.从中世纪暖期到小冰期,石将军洞石笋δ^(13)C持续偏重;在同一时期,中国西南区域其他石笋和钙华的δ^(13)C记录都表现出同样显著偏重的趋势.由于石笋δ^(13)C记录能够反映洞穴上部的生态环境变化,因此中国西南区域石笋δ^(13)C一致的变化可能反映了中国西南喀斯特地区石漠化扩张的过程.中世纪暖期亚洲夏季风加强,雨带北移,导致了中国西南干旱,北方湿润;相反,在小冰期中国西南湿润,北方干旱.此外,北宋末年靖康事件(AD1127)后中国政治经济中心首次迁移到中国南方,改变了历史上中国人口北多南少的分布模式.因此,中世纪暖期中国西南干旱的气候和大量人口的迁入、战争、大规模开垦耕地以及大面积农作物的种植,加剧了中国西南石漠化的扩张.

基于陕南祥龙洞石笋XL2的19个^(230)Th年龄、218个氧同位素分析以及896个Sr/Ca分析数据,高分辨率重建了4200~1972a B.P.期间陕南地区季风降雨变化。重建结果显示陕南地区这一时期季风降雨有显著的127~105a和57a周期,可能分别受控于太阳活动、PDO和/或AMO的变化。重建时段有3次百年尺度的干旱事件,分别发生于2200~2100a B.P.,2900~2700a B.P.和3600~3400a B.P.,其中2900~2700a B.P.干旱事件对应于北大西洋地区2.8ka冷事件。对比研究显示,尽管祥龙洞石笋和董哥洞石笋δ^(18)O记录整体一致,但除了2900~2700a B.P.干旱事件之外,其他两次干旱事件在董哥洞石笋记录中并不明显。而尽管总体上祥龙洞和和尚洞石笋δ^(18)O记录的差异要大,但XL2的3次干旱事件在和尚洞记录都有明显体现。有精确年代控制的祥龙洞、董哥洞及和尚洞石笋氧同位素记录的差异,揭示晚全新世我国季风降雨在十-百年尺度存在区域差异。

Arid Central Asia(ACA), with its diverse landscapes of high mountains, oases, and deserts, hosted the central routes of the Silk roads that linked trade centers from East Asia to the eastern *** pockets and ecoclines in ACA are largely determined by local precipitation. However, little research has gone into the effects of hydroclimatic changes on trans-Eurasian cultural exchange. Here,we reconstruct precipitation changes in ACA, covering the mid-late Holocene with a U-Th dated, ~3 a resolution, multi-proxy time series of replicated stalagmites from the southeastern Fergana Valley,Kyrgyzstan. Our data reveal a 640-a megadrought between 5820 and 5180 a BP, which likely impacted cultural development in ACA and impeded the expansion of cultural traits along oasis routes. Instead,it may have diverted the earliest transcontinental exchange along the Eurasian steppe during the 5 th millennium BP. With gradually increasing precipitation after the megadrought, settlement of peoples in the oases and river valleys may have facilitated the opening of the oasis routes, ‘‘prehistoric Silk roads", of trans-Eurasian exchange. By the 4 th millennium BP, this process may have reshaped cultures across the two continents, laying the foundation for the organized Silk roads.

Understanding the initial use stage of cement mortar lining in drinking water distribution systems:Silicon and aluminum as stability indicators

The cement mortar lining(CML)of commonly used ductile iron pipes can severely deteriorate the drinking water quality at the initial stage of use,but the behavioral characteristics of different elements release from the CML in this stage is still *** this study,dynamic immersion experiments with new cement mortar lined ductile iron pipe reactors were conducted under different feed water hardness and alkalinity *** results showed that the release of alkaline substances from the CML at the initial stage of use could strongly influence the pH of water,which consequently greatly impacted the release/precipitation behaviors of calcium,aluminum and *** pH and aluminum concentration of the effluent water could reach 11.5 and 700μg/L within 24 hr of hydraulic retention time,respectively,under conditions of relatively lower hardness and *** to the pH elevation,calcium carbonate precipitation could occur even at much lower feed water *** the aluminum and silicon could keep release from the CML in soluble form at different hardness and alkalinity levels,and their release rate depended on the amount of calcium carbonate ***,aluminum and silicon were more suitable as indicators of the corrosion intensity at the initial stage of CML use rather than the traditional calcium carbonate precipitation *** feed water hardness and alkalinity levels for mitigating the initial intense corrosion of CML were proposed:hardness>40 mg/L(CaCO_(3)),alkalinity>100 mg/L(CaCO_(3)).

Precise dating of abrupt shifts in the Asian Monsoon during the last deglaciation based on stalagmite data from Yamen Cave, Guizhou Province, China

引用

Science China Earth Sciences 2010年第5期53卷 633-641页

作者： edwards r. lawrence Department of Geology and Geophysics University of Minnesota

Based on 33 U/Th dates and 1020 oxygen isotopic data from stalagmite Y1 from Yamen Cave, Guizhou Province, China, a record of the Asian Summer Monsoon (ASM) was established. The record covers the last deglaciation and the early Holocene (from 16.2 to 7.3 ka BP) with an average oxygen isotope resolution of 9 years. The main millennial-scale deglacial events first identified in Greenland (Greenland Interstadial Events: GIS 1e through GIS 1a) and later in China are clearly present in the Y1 record. By analogy to earlier work, we refer to these as Chinese Interstadials (CIS): CIS A.1e to CIS A.1a. The onset of these events in Y1 δ18O records are nominally dated at: 14750±50, 14100±60, 13870±80, 13370±80, and 12990±80 a BP. The end of CIS A.1a or the beginning of the Younger Dryas (YD) event is nominally at 12850±50 a BP and the end of the YD dates to 11500±40 a BP. The δ18O values shift by close to 3‰ during the transition into the Bφlling-Allerφd (BA, the onset of CIS A.1e) and at the end of the YD. Comparisons of Y1 to previously published early Holocene records show no significant phase differences. Thus, the East Asia Monsoon and the Indian Monsoon do not appear to have been out of phase during this interval. The Y1 record confirms earlier work that suggested that solar insolation and North Atlantic climate both affect the Asian Monsoon.

An article by Zhang et al. questions the interpretation of our oxygen isotope record from Wanxiang Cave and the sediment titanium record from Lake Huguang Maar,and the possible linkage between climate change and Chinese culture. In response,we explain that their approach lacks logical rigor and their major argument is broadly consistent with,rather than contradictory to our original conclusions. We also note that climate-culture relationships similar to those that we observe in China have been observed for other cultures around the world.
