THE BLACK-NECKED CRANE IN CHANGTANG

正If the Tibetan antelope is an elf among the highland animals,then the black-necked crane is undoubtedly the socialite among the birds on the Qinghai-Tibet Plateau.Gruidae are divided into four genera and fifteen species,of which the black-necked crane is the only one living and multiplying on the highland.The herdsmen in Changtang give it a sweet     

SNOWFINCHES IN CHANGTANG

正Snowfinches are passerine birds which live in high altitude areas.As the name implies,they are not afraid of the cold.One can see them playing everywhere even when it is under twenty or thirty degrees below zero Celsius in the cold Changtang winter.Snowfinches are slightly larger than Eurasian tree sparrows and can be seen in both no man's land and areas full of human activity.They have a relatively darker coat in summer and are     

THREE DAYS IN CHANGTANG

<正>Day One It was August 2013 when I first arrived in Changtang as a volunteer for WCS China.As our car was approaching the grassland,the air smelled a bit different,with the cool breeze of snowy mountains and the brisk smell of the prairie.When I saw the first Tibetan antelope holding her magnificent horns proudly high and staring at us for a while,I felt I was living in a dream.This was my first impression of Changtang.

WILDLIFE PROTECTION FIELD WORK IN CHANGTANG

<正>"It breaks my heart looking at the door of my house!"In the guest house of Gumu Township government,a local herdsman was trying to describe for us how his home was wrecked by a brown bear.Inside the room,the smell of mutton and butter lingered in the air.Outside,there was the perfectly typical blue sky of Tibet.It was already June,but the weather was still chilly and windy on the Changtang grassland.The down jacket I put away only a month ago     

THE THREE KNIGHTSIN THE CHANGTANG GRASSLAND

<正>Changtang grassland is a unique and large landscape with a high altitude and harsh climate and is unsuitable for human life.However,it is home to many specific species,including the three knights:the wild yak(Bosmutus),the wild donkey(Equus kiang),and the Tibetan antelope(Pantholops hodgsoni),who range widely on the highland of northern Tibet.

羌塘自然保护区的守护者

Welcome to the Changtang National Nature Reserve,a place with annual average temperatures at or below freezing,oxygen about half that of sea level,and a prairie lying at an altitude 5,000 meters high.Found in the northern reaches of the Qinghai-Tibet Plateau,humans can rarely,if ever,be found here,but wildlife abound,many animals among the rarest and most precious in the world.Within such an inferior natural environment,there are groups of special guardians tasked with protecting wildlife from year to year.

THE CHLOR-ALKALI INDUSTRIES IN THE USSR

Spatial patterns in the production of chlor-alkali chemicals (soda ash, caustic soda, and chlorine) in the USSR are examined. The opening of large new salt deposits in the Volga region in the 1950s not only increased output of soda ash considerably, but also dramatically shifted production because of soda ash's raw material orientation. In contrast, because caustic-chlorine production tends to be market oriented, it was mainly the development of chlor-organic synthesis in the 1960s and 1970s that resulted in much greater spatial dispersion of production. Overall, the industry is now in a slow-growth phase, following the rapid gains made during the postwar period. Soda ash production is actually declining, while the wide array of applications for chlorine, especially chlorinated hydrocarbons, promises continued growth for the caustic-chlorine sector.     

THE OLIVE IN THE PREHISTORIC AEGEAN: THE EVIDENCE FOR DOMESTICATION IN THE EARLY BRONZE AGE

Summary. In 1972 Colin Renfrew suggested that the rise of Mycenaean civilization may have been made possible by the development of a polycultural triad of wheat, vine and olive in the Early Bronze Age. A careful examination of the botanical and archaeological evidence for the domestication of the olive lends little support to this aspect of the thesis. The palynological evidence from various points in Greece is inconclusive, but for most areas it would seem to suggest that the intensive cultivation of olive began in the Late Bronze Age or even later.
No conclusive archaeological evidence for processing or storage of olive oil exists for any period in the Bronze Age. The question of when olive domestication took place must remain unanswered until more data are available from Early and Middle Bronze Age contexts and more conclusive botanical data have been collected.
