Place Descriptions

Place descriptions record qualitative information related to places and their spatial relationships; thus, the geospatial semantics of a place can be extracted from place descriptions. In this study, geotagged microblog short texts recorded in 2017 from the Tibetan Autonomous Region and Qinghai Province were used to extract the place semantics of the Qinghai–Tibetan Plateau (QTP). ERNIE, a language representation model enhanced by knowledge, was employed to extract thematic topics from the microblog short texts, which were then geolocated and used to analyze the place semantics of the QTP. Considering the large number of microblogs published by tourists in both Qinghai and Tibet, we separated the texts into four datasets according to the user, i.e., local users in Tibet, tourists in Tibet, local users in Qinghai, and tourists in Qinghai, to explore the place semantics of the QTP from different perspectives. The results revealed clear spatial variability in the thematic topics. Tibet is characterized by travel- and scenery-related language, whereas Qinghai is characterized by emotion, work, and beauty salon-related language. The human cognition of place semantics differs between local residents and tourists, and with a greater difference between the two in Tibet than in Qinghai. Weibo texts also indicate that local residents and tourists are concerned with different aspects of the same thematic topics. The cities on the QTP can be classified into three groups according to their geospatial semantic components, i.e., tourism-focused, life-focused, and religion-focused cities.

AbstractOn Earth’s surface, there are only a handful of high-quality astronomical sites that meet the requirements for very large next-generation facilities. In the context of scientific opportunities in time-domain astronomy, a good site on the Tibetan Plateau will bridge the longitudinal gap between the known best sites1,2 (all in the Western Hemisphere). The Tibetan Plateau is the highest plateau on Earth, with an average elevation of over 4,000 metres, and thus potentially provides very good opportunities for astronomy and particle astrophysics3–5. Here we report the results of three years of monitoring of testing an area at a local summit on Saishiteng Mountain near Lenghu Town in Qinghai Province. The altitudes of the potential locations are between 4,200 and 4,500 metres. An area of over 100,000 square kilometres surrounding Lenghu Town has a lower altitude of below 3,000 metres, with an extremely arid climate and unusually clear local sky (day and night)6. Of the nights at the site, 70 per cent have clear, photometric conditions, with a median seeing of 0.75 arcseconds. The median night temperature variation is only 2.4 degrees Celsius, indicating very stable local surface air. The precipitable water vapour is lower than 2 millimetres for 55 per cent of the night.

A “zoo” and “mock-up”: On the most frequent ways of portraying BirobidzhanThe article analyses the most common ways of depicting Birobidzhan by journalists, bloggers, film-makers and writers. Established in 1934, The Jewish Autonomous Region is an administrative unit within the Russian Federation. Foreign visitors and visitors from other parts of Russia usually perceive it as “exotic”, “funny”, “absurd”, “grotesque” or “artificial”. Its history is seen as a “failure”, especially when compared to Israel. In various representations, the notion of “utopia” is used in a very narrow, negative sense of “unrealistic pipe dream”. This orientalisation results in the objectification of local residents and delegitimisation of their practices of making sense of the region's history. „Zoo” i „makieta”. O dominujących sposobach pisania o BirobidżanieW artykule przeanalizowane zostały najczęstsze sposoby opisywania Birobidżanu przez dziennikarzy, blogerów, filmowców i pisarzy. Utworzony w 1934 r. Żydowski Obwód Autonomiczny wciąż istnieje jako jednostka administracyjna w ramach Federacji Rosyjskiej. Zazwyczaj traktowany jest przez odwiedzających z innych części Rosji lub z zagranicy jako „egzotyczny”, „śmieszny”, „absurdalny”, „groteskowy” czy „sztuczny”. Jego historia postrzegana jest jako „porażka”, zwłaszcza w porównaniu z historią Izraela. Autorzy rozmaitych przedstawień Birobidżanu posługują się także koncepcją „utopii” w jej zawężonym, negatywnym rozumieniu, jako „nierealnej mrzonki”. Orientalizacja Żydowskiego Obwodu Autonomicznego przyczynia się do uprzedmiotowienia jego mieszkańców i delegitymizowania ich praktyk nadawania sensu historii regionu.

Important Significance

Gas hydrate samples were collected in Muli area (Qinghai Province, China) of Tibetan Plateau permafrost, which is the first discovery of gas hydrate in Chinese permafrost and in the low to middle latitude permafrost of the world. Although the exploitation of gas hydrate in Tibetan Plateau permafrost has lots of important significance, environmental risks including permafrost and alpine meadow ecosystem degeneration, global climate influence, and environmental pollution would take place in the exploitation process. In order to avoid or decrease the risk, safe and dependable exploitation technique, carbon capture and storage technology, engineering process control, legislation and emergency preparatory scheme should be put into practice.

Abstract Two adjacent glaciers collapsed consecutively in the Western Xizang Autonomous Region, China, on July 17 and September 21, 2016, presumably triggered by relatively intensive climate change in this region, leading to massive downstream ice and mud avalanches. After these twin glacier collapses, there have been many researches, which mainly focus on the physical characteristics of these two glaciers while lack the differences between them and the other glaciers. In this study, the geometric features and energy distribution along the glacier centerlines are investigated to identify the differences between these two collapsed glaciers and other glaciers in the western Tibetan Plateau. The anomaly of climate change is presumed to be the trigger of the twin glacier collapses in accordance with existing research results, whereas in this study, the striking geometric similarity between the centerlines of the twin glaciers, which is quantitatively interpreted by the Fréchet distance among the glacier centerlines, unearth some novel mechanisms. The essential point in these new mechanisms is the energy distribution along the glacier centerlines. A hypothesis based on the principle of energy conservation is derived to demonstrate the mechanisms and dynamic processes of the glacier collapses. Furthermore, on the basis of the geometric similarity and energy distribution of the glacier centerlines, a risk assessment of glacier collapse in the western Tibetan Plateau is implemented to facilitate glacier disaster prevention.
