Climate change and catchment modifications induced by human activities are the main drivers playing a significant role in the dramatic variation of water levels in the lake (Dh); hence, it is crucial to provide a better understanding of the impacts caused by these phenomena. However, their respective contribution to and influence on water level variations in Qinghai Lake are still unclear and without characterizing them, targeted measures for a more efficient conservation and management of the lake cannot be implemented. In this paper, data monitored during the period 1960–2016 (e.g., meteorological and land use data) have been analyzed by applying multiple techniques to fill this gap and estimate the contribution of each parameter recorded to water level variations (Dh). -
Evaluation and Validation of Cryosat-2-Derived Water Levels Using in Situ Lake Data from China

In this study, a concentrated probability density function (PDF) method was proposed for preprocessing CryoSat-2 Geophysical Data Record (GDR) data. CryoSat-2 altimetry water levels were preprocessed and evaluated by in situ gauge data from 12 lakes in China. Results showed that the accuracy of the raw GDR data was limited due to outliers in most of the along-track segments. The outliers were generally significantly lower than the in situ values by several meters, and some by more than 30 m. Outlier detection, therefore, improves upon the accuracy of CryoSat-2 measurements. The concentrated PDF method was able to greatly improve the accuracy of CryoSat-2 measurements. The preprocessed CryoSat-2 measurements were able to observe lake levels with a high accuracy at nine of the twelve lakes, with an absolute mean difference of 0.09 m, an absolute standard deviation difference of 0.04 m, a mean root mean square error of 0.27 m, and a mean correlation coefficient of 0.84. Overall, the accuracy of CryoSat-2-derived lake levels was validated in China. -

Guntram Hazod Introduction1 Hapter Two of the Old Tibetan Chronicle (PT 1287: L.63-117; Hereafter OTC.2)
THE GRAVES OF THE CHIEF MINISTERS OF THE TIBETAN EMPIRE MAPPING CHAPTER TWO OF THE OLD TIBETAN CHRONICLE IN THE LIGHT OF THE EVIDENCE OF THE TIBETAN TUMULUS TRADITION Guntram Hazod Introduction1 hapter two of the Old Tibetan Chronicle (PT 1287: l.63-117; hereafter OTC.2)2 is well known as the short paragraph that C lists the succession of Tibet’s chief ministers (blon che, blon chen [po]) – alternatively rendered as “prime minister” or “grand chancel- lor” in the English literature. Altogether 38 such appointments among nineteen families are recorded from the time of the Yar lung king called Lde Pru bo Gnam gzhung rtsan until the end of the Tibet- an empire in the mid-ninth century. This sequence is conveyed in a continuum that does not distin- guish between the developments before and after the founding of the empire. Only indirectly is there a line that specifies the first twelve ministers as a separate group – as those who were endowed with 1 The resarch for this chapter was conducted within the framework of the two projects “The Burial Mounds of Central Tibet“, parts I and II (financed by the Austrian Science Fund (FWF); FWF P 25066, P 30393; see fn. 2) and “Materiality and Material Culture in Tibet“ (Austrian Academy of Sciences (AAS) project, IF_2015_28) – both based at the Institute for Social Anthropology at the Austrian Academy of Sciences.

Qinghai Institute of Salt Lakes, Chinese Academy of Sciences, Xining 810008, China; 2. Library, China University of Geosciences, Wuhan 430074, China) Abstract: This study investigated late Pleistocene environmental change indicated by proxies (grain size, magnetic susceptibility, color reflectance, and total organic carbon) of the 240 cm-deep XT section in the Xitaijinair salt lake region. The results suggest that: (1) Sediments in the XT section are generally fine (median grain size ranging from 3.4 μm to 10.0 μm), but are coarse at the depth of 25 ~ 47 cm and 185 ~ 199 cm (median grain size varying from 15.7 μm to 59.0 μm). (2) Median grain size is positively correlated with low-frequency magnetic susceptibility (χlf). Redness a* is negatively correlated with χlf . 18 (3) Tentative comparison with χlf records in the XT section and δ O records in the global deep oceans shows that the Pleistocene climate change in the Xitaijinair salt lake region is possibly influenced by global climate. -

The working-age population decreased by leading economic power; it was also one of the world’s 3.5 million in 2012. The labor force in the mining sector was leading mineral producing and consuming countries. In 2012, 6.11 million, or 4.2% of the country’s total workforce in 2011. China’s economy remained strong compared with most of the In the manufacturing sector, rising production and developed countries in the West.

The country’s demand for energy, decreased significantly to 19.1% in November from 23.2% metals, and minerals was particularly strong. China imported in August, and the trend toward decreased production was significant amounts of raw materials and transformed the mirrored in the cement sector as well.
