基于地理国情普查对开发冰雪丝绸之路旅游带的思考     

龚强 《东北测绘》2014,(6):4-6

黑龙江省第一次地理国情普查已全面展开,其目的是全面掌握黑龙江地理国情现状,系统掌握全省自然、人文地理要素的现状和空间分布情况。黑龙江省是资源大省,除煤、木、粮、油、机外,旅游资源也十分丰富。作为连接中原与黑龙江地区的水陆大通道,黑龙江冰雪丝绸之路比西北丝绸之路早了1000多年,且一直繁荣了几千年,存有大量的历史遗迹,但近百年来却鲜为人知。充分利用基于现代测绘地理信息技术获得的地理国情数据和信息,恢复和开辟黑龙江冰雪丝绸之路旅游带,对弘扬黑龙江历史文化,宣传黑龙江意义重大,功在当代,利在后世。  相似文献   

从DNA角度认识中国黄牛的起源和利用历史     

陈宁博  雷初朝 《第四纪研究》2022,42(1):92-100

中国黄牛的起源及驯化一直是遗传学家和考古学家共同关注的热点问题.中国拥有丰富的牛种资源,仅中国地方黄牛品种就多达55个,境内及周边还分布着能与黄牛杂交的近缘野牛,这导致中国黄牛的遗传背景和形成历史非常复杂.利用DNA可以解析中国黄牛的起源和利用历史,通过Y染色体、线粒体和核基因组遗传标记已经从父系遗传、母系遗传和基因组...  相似文献   

Beach Ridge Geomorphology at Cape Grinnell,northern Greenland: A Less Icy Arctic in the Mid-Holocene     

Owen K. Mason 《Geografisk tidskrift / udgivet af Bestyrelsen for Det Kongelige danske geografiske selskab》2013,113(2):337-355

Geografisk Tidsskrift—Danish Journal of Geography 110(2):337–355, 2010

In northern Greenland, the Cape Grinnell beach ridge plain offers a 9,000year multi-proxy record for isostatic recovery, storm history, and the hydrological changes related to precipitation and slope evolution. The chronology of uplifted beach ridges is constrained by ten geological 14C ages on shell and sea mammal bones and eleven upper limiting ages from archaeological sites that span the last 3,000 years. Beach ridges formed under the influence of open water storms with renewed frequency and intensity ca. 3 ka and 1 ka ago. A lack of shell may reflect cooler sea surface temperatures. The presence and absence of ice can be inferred by push-features. Three intervals of heightened precipitation produced extensive fan deltas: (a) after 9 ka BP (b) prior to 4.5 ka BP and (c) during the Little Ice Age (AD 1350–1900). Active solifluction lobes and colluvia cover beach ridge deposits that are between 9 and 7 ka old.  相似文献

The beginning of geography didactics in Norway     

Per Jarle Sætre 《Norsk geografisk tidsskrift. Norwegian journal of geography》2013,67(3):120-127

At the end of the 19th century geography became a mandatory subject in primary and secondary schools in Norway. Geography was seen as a useful subject that contributed to the modernization of society, but also as a subject that strengthened the national ideology. A need for better education in geography arose and consequently some authors of geography textbooks wrote about teaching geography. In order to strengthen teachers’ education, geography was taught at university level, and to develop the subject it became necessary to relate it to other subjects, especially geology. The author shows that there are several similarities between the content of geography taught in Norwegian schools in the late 19th century and geography taught in schools today.  相似文献   

Unpopular Archives     

Karen M. Morin 《The Professional geographer》2013,65(4):534-543

This article explores the “unpopular” archived life of Charles P. Daly, thirty-five-year president (1864–1899) of the New York–based American Geographical Society. This one-time highly prominent judge and civic leader popularized geography among professionals and the public alike. Daly's popular geography, along with his subsequent containment within the archives, suggests explanations for his dismissal among geographical audiences of today. It is a useful and necessary exercise to trace the neglect of Daly within histories of geography and recapture him for today's audiences, not only because of his influence on post–Civil War American geography but also because his story can shed light on how “disciplinary remembering” functions in geography.  相似文献

AN EVALUATOR'S VIEW OF NDEA INSTITUTE PROPOSALS     

《The Professional geographer》2013,65(1):38-40

This paper analyzes the surprisingly great variation in demographic character across the states, utilizing data on fertility, mortality, age, sex, mobility, household character, abortion, race and ethnicity. A fairly simple regional pattern is revealed that is less related to levels of economic development than to long-standing historical cultural differences.  相似文献   

Commentaries on “Automated Geography”. Automated Geography and the DIDS (Decision Information Display System) Experiment     

《The Professional geographer》2013,65(3):339-340

Age profiles of geographers having varying topical and areal subfields are compiled using the Guide to Graduate Departments of Geography in the United States and Canada, 1983–1984 and the 1982 AAG Directory. Major retirement trends for the next 10 to 20 years suggest that replacement of faculty may raise key appointment issues and priorities that may significantly change the nature of academic geography.  相似文献   

Population dynamics of mayflies in a constant temperature spring stream in West Carpathians     

Kvetoslava Bottová  Tomáš Derka  Marek Svitok 《Limnologica》2013,43(6):469-474

We examined the life history and secondary production of four Ephemeroptera species (Baetis alpinus Pictet, 1843–1845, Baetis rhodani Pictet, 1843–1845, Rhithrogena carpatoalpina Klonowska, Olechowska, Sartoriet & Weichselbaumer, 1987 and Habroleptoides confusa Sartori & Jacob, 1986) in a temperature stable cold spring stream at Prosiek valley (Cho?ské vrchy Mts., West Carpathians, Slovakia). We have found asynchronous bivoltine life cycle for the most abundant species B. alpinus with growth rate positively correlated to photoperiod length. R. carpatoalpina have shown unusual asynchronous univoltine life cycle and B. rhodani have shown uncommonly low abundance in mayfly community. Total secondary production of mayfly community was very low, reaching 1654.8 mg DW m^?2 y^?1. We suggest that the observed asynchrony in growth could be related to the lack of temperature control.  相似文献
