The Neogene eolian deposits in the Chinese Loess Plateau(CLP) are one of the most useful continental deposits for understanding climatic changes. To decipher Late Neogene paleoclimatic changes in the CLP, we present a terrestrial mollusk record spanning the time interval between 7.1 and 3.5 Ma from the western CLP. The results indicate four stages of paleoclimatic evolution: From 7.1 to 6.2 Ma, cold and dry climatic conditions prevailed as evidenced by high values of the total number of cold-aridiphilous(CA) mollusk species and by low values of all of the thermo-humidiphilous(TH) mollusk indices. From 6.2 to 5.4 Ma, the climate remained cold and dry but was not quite as dry as during the preceding phase, as indicated by the dominance of CA mollusks and more TH species and individuals. From 5.4 to 4.4 Ma, a warm and moist climate prevailed, as indicated by high values of the TH species and individuals and by the sparsity of CA species and individuals. From 4.4 to 3.5 Ma, all of the CA indices increased significantly and maintained high values;all of the TH indices exhibit high values from 4.4 to 4.0 Ma, an abrupt decrease from 4.0 Ma and a further increase from 3.7 Ma. The CA species of Cathaica pulveraticula, Cathaica schensiensis, and Pupopsis retrodens are only identified in this stage, indicating that the CA species were diversified and that the climate was becoming drier. Moreover, the CA mollusk group exhibits considerable diversity from 7.1 to 5.4 Ma when a cold, dry climate prevailed;whereas the diversity of the TH group was high during the relatively warm, wet interval from 5.4 to 4.4 Ma. This indicates that variations in the diversity of the CA and TH mollusk groups were closely related to climatic changes during the Late Miocene to Pliocene.

通过对黄土高原西峰和洛川黄土剖面末次冰期较高分辨率的蜗牛化石组合研究发现,深海氧同位素第3期(MIS3)(59～29kaB.P.)黄土高原的气候变化可分为3个阶段:MIS3c时期,气候总体相对温暖湿润,但暖湿程度远不及全新世时期,这一阶段出现两次比较温湿的气候波动,西峰最温湿的时期发生在约48～46kaB.P.,其次在约54kaB.P.,洛川较温湿的时期出现在约57kaB.P.;MIS3b时期,西峰气候比较寒冷,但具有一定的湿度,洛川总体上气候比较冷湿,但较之于西峰无论是温度还是湿度都要高一些;MIS3a时期,西峰的气候从温凉变得冷干,洛川出现频繁的气候波动。研究认为黄土高原MIS3c时期较温湿气候状况可能是受控于这一时期地轴倾角控制的太阳辐射梯度的变化,地轴倾角增大,中纬度夏季太阳辐射强度高于低纬度的辐射强度,使得中低纬度之间夏季太阳辐射梯度增加,低纬度海洋向中纬度大陆传输的热量和湿度增加,夏季风加强,从而改善了黄土高原的温湿度状况,喜暖湿的蜗牛种类得以在冰期的环境中生长发育。蜗牛化石的研究结果显示MIS3时期黄土高原不同地区存在明显的区域性差异,与现今气候格局不同的是这一时期黄土高原存在更大的气候环境梯度。

Here we presented a high-resolution 5350-year pollen record from a maar annually laminated lake in East Asia(EA). Pollen record reflected the dynamics of vertical vegetation zones and temperature *** analysis on pollen percentages/concentrations of Pinus and Quercus, and a temperature proxy,revealed,500-year quasi-periodic cold-warm fluctuations during the past 5350 years. This,500-year cyclic climate change occurred in EA during the mid-late Holocene and even the last 150 years dominated by anthropogenic forcing. It was almost in phase with a,500-year periodic change in solar activity and Greenland temperature change, suggesting that,500-year small variations in solar output played a prominent role in the mid-late Holocene climate dynamics in EA, linked to high latitude climate system. Its last warm phase might terminate in the next several decades to enter another,250-year cool phase, and thus this future centennial cyclic temperature minimum could partially slow down man-made global warming.

Noodles are a global food, but the periods when and places where they were made and originated, as well as their ingredients and the cooking methods used to manufacture them, have remained contentious. In the 2005 edition of the journal Nature, we wrote a summary of the millet noodle specimens found in the Late Neolithic Qijia cultural stratum of the Lajia archaeological site in Qinghai Province, China. However, how the ancient people made millet noodles remains controversial. This paper provides a systematic analysis of the remains of noodles found within an earthenware bowl at the Lajia ‘‘noodle house’’ in terms of their plant composition including phytoliths, starch and biomarkers. It provides evidence of how people used millet4,000 years ago and, most specifically, of the principal methods used for producing millet-based noodles. Further,we show how we used traditional hele tools to make hele millet noodles, with especial reference to the gelatinized hydrogel-forming method, to simulate morphology consistent with the composition and form of the unearthed millet noodles. The results of this study provide new evidence and new insights into the cultural characteristics of the prehistoric human diet.
