THE BOXER ON THE ROOF OF THE WORLD

正Though the Tibet boxing team might be rarely heard of,Sonam Norbu,a national master sportsman from the first Tibet boxing team with a weight of 52 kilograms,has won a gold medal for the 2011 National Youth Fight,a bronze medal for the 2012 National Championship,and another bronze medal for the 2013 National Championship.The Tibet boxing team is still young today.Asked why he chose to be a boxer,     

NOMADIC FAMILIES ON THE ROOF OF THE WORLD

正On an unforgiving land situated at an altitude of over 5,000 meters upon northern Tibet is a group of ethnic Tibetans who are keeping on with their nomadic traditions inherited from their ancestors.They are accompanied with yaks and sheep as they live on the land,but the tide of modernization has brought them     

PLANTING TREES ON THE ROOF OF THE WORLD

正In China,legend says that animals choose different trees to inhabit.In Nagqu,situated on the northern area of the Tibet Autonomous Region,trees are nowhere to be seen,and birds often share holes underground with mice and rabbits.Nagqu means"black river"in Tibetan.The place is situated     

世界屋脊上的“最美”医生

Most Tibetan people regard Losar,the Tibetan New Year,as a time for families to come together,but Tsering Pedron instead spends her time treating patients at the Ngari People's Hospital in Ngari Prefecture."I recognize the importance of seeing one's family during the New Year and other key festivals,but if I purely give my time to my family,who else would be there for my patients should they need me?"said Tsering Pedron,who is the Ob-Gyn director of the hospital.She has only gone home to see her family and celebrate the holiday once since 1993.     

互联网技术应用对零售业空间组织影响研究进展

互联网技术应用对零售业空间组织的影响已成为当今学术界研究热点。本文利用文献资料法和对比分析法,梳理了国内外互联网技术应用对零售业空间组织结构、零售企业区位选择与布局、市场空间等方面的影响研究,并提出了未来人文地理学须进一步强化的研究内容。结果表明：20世纪90年代中期以来,互联网技术应用对零售业空间组织影响的研究成果日益丰富,且涉及到经济地理学和商业学等学科,研究方法主要以定性为主,且定量研究日益增多,但对互联网技术应用对传统零售业区位选择和销售腹地的影响、中小网络零售企业空间组织、运输距离对网络零售企业销售空间影响以及出口跨境网络零售企业销售空间格局等方面研究还需完善,未来研究应注重吸收其他学科理论和方法,强化实证研究结论的科学性。     

基于弱势群体需求的北京服务设施可达性集成研究

关注人群属性和需求,探讨服务设施供给的社会公平是新时代服务设施研究的重要议题,对于人口总量巨大、社会构成多元、社会空间分异凸显的大城市尤其如此。尽管研究某一弱势群体对单项服务设施需求的文献不断涌现,但是结合居民主观的服务设施需求偏好的可达性集成研究尚不多见。本文以北京作为案例城市,首先采用居民主观调查数据分析四类弱势群体对于公共服务设施的需求结构,然后基于POI数据,借助GIS分析这四类弱势群体服务设施需求偏好下的北京市公共服务设施综合可达性情况,且对综合可达性较差的区域进行了空间识别。本研究综合定性与定量方法,探讨主观与客观数据相匹配的可达性集成方法,可以为今后的相关研究提供借鉴,并能够对北京建设国际一流和谐宜居之都提供理论支撑。     

略论现代化国际性城市的基本特征

现代化城市具有总体布局合理、基础设施完善、环境质量优良、第三产业发达等基本特征;国际性城市则主要以经济实力雄厚、国际投资与金融机构众多、科技教育事业发达、城市风貌独特、连接国内与世界经济等为其标志。     

THE IMPACT OF THE SYSTEM OF MINOR CIVIL DIVISIONS ON AGRICULTURE

Mathematical techniques are used to test the hypothesis that Soviet farm efficiency, as reflected in farm profit rates, is higher in areas where the boundaries of collective and state farms coincide with the boundaries of rural soviets, the lowest local government areas. Conversely, farm performance suffers when farm territories are broken up among two or more rural soviets. The use of Karl Pearson's coefficient of contingency, which may be used to measure the strength of a relationship between qualitative variables, shows a positive relationship between farm profit rates and boundary coincidence. The authors therefore urge frequent review of local government areas to insure that they correspond to the boundaries of agricultural operating units.     

奥运会对城市经济的助推作用

本文主要讨论了现代奥运会在城市经济活动中的作用以及不断增强的产业化。企业化促使奥运承办费用日益增长,同时对举办城市经济的影响日益加大。2008年北京奥运会的申办以及预期结果表明:现代城市为获得奥运会主办权而不断增强的竞争,已经成为城市经济发展的重要组成部分。     

LANDSCAPE AS A SUBJECT OF HUMAN IMPACT

A continuing critique of the Soviet school of anthropogenic landscape science (see Soviet Geography, October 1974) questions whether man is, in fact, capable of creating “new” landscapes or his intervention in the natural environment simply tends to “modify” existing natural landscapes. The author rejects the view that significant modification of anyone of the components of landscape (including flora and fauna) is sufficient to produce an anthropogenic landscape or that a cutover forest area or a cattle trail, for example, represents a newly created landscape. A genuine modification of landscape requires an alteration of the basic structure of landscape, and this can be achieved only through modification of primary landscape components, such as the geomorphic foundation and climate. These are precisely the components that are less susceptible to human intervention than secondary components like plant and animal communities. Another criterion of basic landscape modification is stability; most anthropogenic landscapes turn out to be unstable when abandoned. Man achieves the most stable results in landscape modification by acting in concert with natural dynamic tendencies in the landscape.     

ON THE IMPACT OF COMPETITION ON TRADE AND FIRM LOCATION

We study how the level of trade costs and the intensity of competition interact to explain the nature and intensity of trade within a given industry and the location of firms across countries. As trade costs decrease from very high to very low values, the global economy moves from autarky to two‐way trade, through one‐way trade from the larger to the smaller region. By exploring the intensive and extensive margins of exports, we investigate how the intensity of trade reacts to the degree of competitiveness. Furthermore, when firms are free to change location, they flow from the small to the large country, and the larger country is always a net exported on the manufactured good. Firms located in the big country have a bigger size than those located in the small one. Under one‐way trade, the relocation of firms changes their attitude toward export.     

交通经济带的基本理论探讨

伴随工业化和运输化的进程,一种依托交通干线融合、集散人口、产业、城镇、物流、能流、信息流的线状空间地域综合体不断生成并带动区域经济系统迅速发展,这种独特的空间地域综合体被经济地理学家和运输经济学家称为交通经济带（ＴｒａｆｉｃＥ－ｃｏｎｏｍｉｃＢｅｌｔ,ＴＥＢ）。本文在简要回顾交通经济带研究历程的基础上,界定了交通经济带的基本概念、基本性质、基本类型以及时空演化机理。
