The Tibetan Red Deer(Cervus canadensis wallichi) is also called the Sikkim red deer and is pronounced "xiawa" in the Tibetan language.It is a special member of the red deer family and a unique species to the Tibet Autonomous Region.The Tibetan red deer was first discovered by scientists about 150 years ago.Because of its status in the Convention on International Trade in Endangered Species of Wild Fauna and Flora as being endangered,the Tibetan red deer was listed before the white-lipped deer,which is under first-level key  相似文献

Recent petrochemical developments in Alberta are part of a global redistribution of the industry toward raw material locations. A small group of companies has secured control of these raw materials within Alberta and, as a consequence, the power to determine the future pattern of petrochemical development within the province. This pattern will reflect the requirements of the companies rather than the economic policy objectives of the Alberta government.

正It is said that Tibetans can dance as soon as they could can walk and sing as soon as they can talk.Actually,other creatures living in Tibet are no exception.The mountains,forests,rivers,and wilderness are alive with song all the time.Listen carefully,the songs of nature can be grand at some times and subtle at other times.  相似文献

In the present paper the author makes an attempt to generalize and analyze the fi nds of the late Neolithic and Paleometal Periods from the Middle and Lower Yangtze. The presence of stable contacts (including ethnologically signifi cant traits) is traced between the ancient cultures of this region and the Indochina Peninsula, inhabited by representatives of Austroasiatic peoples (the Viet, the Khmers). Based on comparisons, the Bronze and Iron Age inhabitants of the major part of South China are concluded to be Austroasian. Particular attention is paid to the Wucheng culture and its complex social structure.  相似文献

Abstract

Bennie Keel’s 1972 work at Upper Sauratown was the opening salvo of the Research Laboratories of Archaeology’s 30-year Siouan Project, which continues under the guise of the ongoing Catawba Project. Keel’s early work at the protohistoric Hardins and early historic era Belk Farm sites in the Catawba River Valley continues to inform the current phase of Piedmont Siouan research. This study compares and contrasts Keel’s Hardins and Belk Farm ceramic assemblages with those from the later Catawba sites of Nassaw Town, Old Town, and New Town to achieve a diachronic view of Catawba ceramic development. This comparison reveals a long span of stylistic and technological continuity abruptly terminated by rapid emergence of the modern Catawba ceramic tradition between 1760 and 1770.  相似文献

Summary. The soil micromorphological analysis of buried soils and probable 'midden' deposits buried beneath alluvium from six sites in the lower Welland valley between Maxey and Etton (Cambridgeshire) has revealed a deforested early Neolithic landscape which quickly became subject to seasonal alluviation. This paper suggests that the Neolithic/Bronze Age use of this landscape is directly related to its interpretation as an alluviated floodplain rather than an alluviated, former dry-land landscape.  相似文献

农业地理环境是农业生产诸自然条件中影响最大的因素之一。历史过程之中,以地理环境条件为基础,伴随农业生产技术的纵深迈进,农业经济的开发与中心转移呈现出明显的层次性与地域性特征:率先是黄河中下游地区的旱作农区,次为长江流域稻作农区,进而是高寒农区的开发。  相似文献

T ime - distance is defined as the time required to travel a specific distance. Consider the time-distances among n places. They are tabulated in an n by n matrix and it is assumed that each element of the square array represents the minimum travel time to go from one place to another. Usually the matrix will be non-symmetrical with all diagonal elements equal to zero. Imagine a graphic representation of those places in a two-dimensional space. Theoretically it is possible to determine two configurations, one arising from trip i to j , the other from trip j to i , such that the locations of all n points approximate the n ( n -1)/2 time-distance relations.1 In practice, however, the geographer will not be satisfied with a solution that does not preserve geographic neighbourliness. He will argue that geographical order is a necessary ingredient to the understanding of place relations. In most cases, a total solution that reconciles the geography with the metric is unattainable and only segments of the time-distance matrix are mapped. On polar isochronic maps, for instance, places are located according to their geographic azimuth and their time-distance with respect to one single origin. Therefore only one row or one column of the original matrix is plotted. The number of maps required for representing the entire data would be twice as large as the number of observations.  相似文献

黄河中下游地区史前人口性别构成研究   总被引:1,自引:0,他引:1  
人口统计学研究并不是单纯从生物学角度研究人口的自然属性,而主要是从社会学角度研究人口的性别构成及其对社会的影响。一般来说,自然界各种生物的两性比例是平衡的,这是生物发展的一般规律,也是物种繁衍发展的需要。人作为自然物种的一支,其两性比例亦应受到这种自然规律的制约。但由于人类具有特有的社会属性,因而在一定时期又存在性比失衡的现象。这种现象直接关系到结婚率和妇女生育率,从而决定人口出生率以及人口再生产速  相似文献

The concept of historical development cycles of a territory is proposed, distinguishing time scales of the order of 10, 100 and 1000 years and spatial scales ranging from local through regional to global. The notion of growth poles is introduced into the space-time stratification of development, and three types of poles are distinguished: (1) permanent poles that maintain their position through a sequence of historical cycles; (2) migrating poles; (3) mutually substituent poles that exchange positions from one cycle to another. Various types of growth poles and development cycles are associated with each of the three time scales. For example, local and regional cycles with permanent poles tend to be associated with short-duration cycles, the global cycles and mutually substituent poles with long-duration cycles.  相似文献

沟域经济背景下的山区空间发展战略研究   总被引:1,自引:0,他引:1  
分析了沟域经济的内涵及其对山区发展战略的影响,提出了"廊道+沟域+节点"的山区空间发展战略模式。以门头沟区为例,其沟域经济发展模式可归纳为"走廊带沟域促节点",这符合提出的山区空间发展战略模式。交通线是沟域经济发展的主要廊道,在空间上打破了传统行政上的界限;沟域是沟域经济发展的主阵地,是山区发展的最佳区域;村庄是山区发展的主要节点,通过集聚式发展,符合山区发展空间优化的原则。  相似文献

中国历史战场地域分布及其对区域发展的影响   总被引:1,自引:0,他引:1  
李燕茹  胡兆量 《人文地理》2001,16(6):61-63,68
战争的发生通常与自然、经济、社会和文化环境有着密切的关系,战场的地理分布也表现出一定的规律性。从秦到清两千余年间,战争频繁,战场遍布全国。内部战争主要分布在黄河流域和长江以北的河南、陕西、江苏、山东、山西、安徽等省;外部战争中心则位于甘肃、河北、陕西、河南、新疆、辽宁和青海等三北地区。战场的地域分布对区域经济、社会及文化的发展有着深远的影响。  相似文献

革命纪念地是我国不同时期革命与建设的历史记录,也具有深厚的军事地理和地缘文化价值,以及良好的生态和质朴的民风,成为文化旅游的重要载体。以此为主题的红色旅游在当代旅游市场上呈现出了良好的市场潜力。特别是随着《2004-2010年全国红色旅游发展规划纲要》的出台,红色旅游蓬勃发展。与此相比,红色旅游目的地的开发管理还不够成熟,开发建设远远落后于其它旅游目的地。本文以抗战大本营--山西省左权县麻田为例,对红色旅游目的地的资源、客源市场、开发建设以及对策进行分析研究。  相似文献

ABSTRACT The paper investigates the importance of history for local economic performance in Italy by studying the role of social capital, which refers to trust, reciprocity and habits of co‐operation that are shared among members of a local community. The paper presents a test based on worker productivity, entrepreneurship, and female labor market participation. Using as instruments regional differences in civic involvement in the late 19th century and local systems of government in the middle ages, it shows that social capital does have economic effects.  相似文献

This essay is the first attempt to compare Reinhart Koselleck's Historik with Hannah Arendt's political anthropology and her critique of the modern concept of history. Koselleck is well‐known for his work on conceptual history as well as for his theory of historical time(s). It is my contention that these different projects are bound together by Koselleck's Historik, that is, his theory of possible histories. This can be shown through an examination of his writings from Critique and Crisis to his final essays on historical anthropology, most of which have not yet been translated into English. Conversely, Arendt's political theory has in recent years been the subject of numerous interpretations that do not take into account her views about history. By comparing the anthropological categories found in Koselleck's Historik with Arendt's political anthropology, I identify similar intellectual lineages in them (Heidegger, Löwith, Schmitt) as well as shared political sentiments, in particular the anti‐totalitarian impulse of the postwar era. More importantly, Koselleck's theory of the preconditions of possible histories and Arendt's theory of the preconditions of the political, I argue, transcend these lineages and sentiments by providing essential categories for the analysis of historical experience.  相似文献
