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 UNGULATE IN CHANGTANG

正Changtang lies in the center of the Qinghai-Tibet Plateau.A paradise of wild animals,Changtang is one of the few places on Earth in which throngs of wild mammals can be observed.According to the forestry department,there are 28mammal,92 bird,and 13 fish species in Changtang.Though the species of wild     

高尔夫 十八洞诱惑

相比于那些遥远而昂贵的欧美球场,东南亚的高尔夫是平易近人的。在这一片没有陡坡、野性和寒冷的土地上,海岛、椰树和温润到人心的服务,给这一片绿色打上了特殊的“东南亚胎记”。很多人把跨出国门打球的第一驿站放在东南亚。     

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.     

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

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     

SKY OVERLORDS OF CHANGTANG:THE HIMALAYAN VULTURE AND THE LAMMERGEIER

<正>Besides the two common giant saprophagous birds of prey pictured above,there is another vulture in Tibet.Vultures are often seen in Lhasa,Lhoka,and some other areas in southern Tibet.A celestial burial ground is the domain of Himalayan vultures and these third vultures,with the Changtang Prairie in northern Tibet being the haven of Himalayan     

PEOPLE SAFEGUARDING LIVES IN CHANGTANG GRASSLAND

<正>"Let me walk into the water and try it,"said Director Tsewang while he was rolling up his pants to his knees.He took out a shovel from the rear door of the car and walked towards the water.He tried to test the depth of the water by using his feet and moved forward slowly.With every step,he trod hard on the ground underwater and constantly used the shovel to clear the way.What he     

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     

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.     

DEFINITION OF THE BOUNDARY OF MOSCOW'S ACTIVE ZONE OF INFLUENCE

The present boundaries of Moscow's suburban zone are tested by delineating a so-called zone of active influence of Moscow city based on demographic structure and the significance of commuting to work in the city. The most favorable age-sex structure, with a high percentage of population in the working age groups and a relatively high percentage of children, is found in a zone within 50 to 60 kilometers from the city limits. This zone generates a daily flow of more than 500,000 commuters to places of employment in Moscow, 90 percent of whom spend less than 110 to 120 minutes traveling each way. These commuters represent about 2 percent of the total working-age population in the suburban zone. On the basis of the demographic structure and commuting linkages, Moscow's zone of active influence is therefore defined as the zone within which 90 percent of the commuters reside, or within 52 kilometers of the city limits. This conforms roughly to the present definition of the suburban zone.     

基于旅游者网络关注度的旅游景区日游客量预测研究——以不同客户端百度指数为例

网络搜索引擎是旅游者获取旅游信息的最重要入口,百度指数通过反映关键词被搜索的次数表征旅游者的网络关注度。文章以三清山为例,首先利用协整理论及格兰杰因果检验分析了PC端和移动端百度指数与实际游客量之间的关系,进一步建立日游客量ARMA模型和分别加入PC 端和移动端百度指数的VAR模型,对游客量预测结果及预测能力进行比较分析,以期通过不同客户端、不同搜索关键词来填补游客量预测过程中旅游网络数据提取的单一性,得到更好的预测效果。发现移动端比PC端百度指数模型具有更好的预测效果,移动端比PC端百度指数对实际游客量的变动具有更好的解释能力。     

ECONOMIC-GEOGRAPHIC PECULIARITIES OF FORMATION OF THE INDUSTRIAL-TERRITORIAL COMPLEXES OF UNION REPUBLICS

Differences in industrial development of the Soviet union republics are found to persist, and the basic factors are analyzed. The presence of a skilled labor force is an important factor in insuring a high level of industrial output per capita and a high rate of return on capital. However, the distribution of labor-intensive industries does not always conform to the availability of labor resources. Such industries have reached a high level in the Baltic republics, where the reproduction rate is low and additional labor must be brought in from the outside, and they have not been fostered in Central Asia, where the rate of natural increase is high. The emphasis on resource-based industries that is characteristic of some republics (oil and gas in Azerbaydzhan and Turkmenia, nonferrous metals in Kazakhstan, etc.) is usually associated with a high level of fixed assets (capital intensity) and a low rate of return as well as low levels of industrial output per capita.

多情境下城市时空间行为的社会分异——以北京不同住房来源居民为例

近年来,居民时空间行为的社会分异已成为学者们广泛关注的话题。然而,已有关于居民时空间行为的社会分异研究中,缺少对于居民活动情境的社会分异的研究。因此,本研究基于时间地理学中对人类活动的情境嵌入性与情境的不同维度的相关理论,以北京清河街道为例,分析不同住房来源居民在日常情境、地理情境和社会情境下的时空间行为的社会分异,尝试从多个情境维度拓展对时空间行为社会分异的理解。研究发现,市场性住房居民“朝九晚五”的活动特征明显,活动同伴选择外向性突出;单位性住房居民职住相对接近,在社区空间内分配时间最长且活动目的多样;安置性住房居民活动较为分散,地理情境与社会情境都呈现出“家庭内向性”特征;保障性住房居民非工作活动的“滞后性”明显,对社区空间的时间分配总体较低。除住房来源因素与个人社会经济因素外,建成环境因素对于居民对社区空间的使用有显著影响。     

空间生产机制下城市景观的拼贴

国内的城市经历了时空压缩且缺乏节制的重建式更新,诸如城市的现代化、与传统的断离以及土地被切分并合法的交换与出售等等,足以表明城市更新在资本化的空间生产中热衷于形而上的景观物化和空间政治经济学的塑造。文章因此以空间的生产为视角,揭示了景观社会中的种种拼贴现象;以"空间矩阵"、"局限性"等概念分析了城市空间的非均衡性及缺少地域类型学严谨的发展。并且认为,空间的生产所生发的社会关系与结构的疏离、景观形式的恣意化以及建成环境的异化等,均是城市更新过程中的症候。最后指出,城市及其景观应当回到日常的自然,思考空间环境的修复与再生不是简单化的拼贴术,而是在于对既有环境的局限性和差异性关注之后的渐进式发展。
