A Review of “The Future of Intermodal Freight Transport: Operations,Design, and Policy”     

Andrew R. Goetz 《The Professional geographer》2013,65(2):298-300

This article analyzes the interrelationship among resource consumption, sociospatial justice, and what is popularly known as global warming by interrogating the ecological footprint of professional geographers, especially in terms of their conference-going involving air travel. In this spirit, the article introduces and employs the concepts of ecological privilege (as well as its inextricably related antithesis, ecological disadvantage) and dys-ecologism as a way to understand the roots and implications of professional geographers’ fossil fuel use and those of globally advantaged classes more broadly. To illustrate this, the article measures the flight-related ecological footprint of the 2011 annual meeting of the Association of American Geographers (AAG) in Seattle, Washington. In doing so, the article examines how professional geographers, in the form of the AAG, have responded to their travel-related ecological footprint. It thus highlights the importance of scrutinizing the complex and dynamic interrelationships among consumption; associated socioecological benefits and detriments and their systemic manifestations; and hierarchy-related and power-infused categories of race, class, and nation—and their spatialities.  相似文献   

All-Sky Surface Radiation and Clear-Sky Surface Energy Budgets: Summer to Freeze-Up in the Western Maritime Arctic     

R. L. Raddatz  T. Papakyriakou  R. J. Galley  M. G. Asplin  L. M. Candlish  B. Else 《大气与海洋》2013,51(5):489-504

The 2009 ArcticNet expedition was a field campaign in the Amundsen Gulf–eastern Beaufort Sea region from mid-July to the beginning of November aboard the CCGS Amundsen that provided an opportunity to describe the all-sky surface radiation and the clear-sky surface energy budgets from summer to freeze-up in the data sparse western maritime Arctic. Because the fractional area of open water was generally larger than the fractional area of ice floes, the net radiation at the water surface controlled the radiation budget. Because the water albedo is much less than the albedo of the ice floes, the extent and duration of open water in summer is an important albedo feedback mechanism. From summer to freeze-up, the net all-sky shortwave radiation declined steadily as the solar angle lowered, while coincidently the net all-sky longwave radiation became increasingly negative. The all-sky net surface radiation switched from positive in summer to negative during the freeze-up period. From summer to freeze-up, both upward and downward turbulent heat fluxes occurred. In summer, a positive surface energy budget residual contributed to the melting of ice floes and/or to the warming of the Arctic Ocean's mixed layer. During the freeze-up period, with temperatures below approximately ?5°C, the residuals were mainly negative suggesting that heat loss from the ocean's mixed layer and heat released by the phase change of water were significant components of the energy budget's residual.  相似文献   

南海渔业资源开发利用的时空特征及其治理     

赵欣 《世界地理研究》2022,31(4):762-772

南海渔业开发为维护我国渔业利益和海洋权益发挥了重大作用,近年来急速衰退的渔业资源和不断升温的冲突态势亟须寻找治理革新的突破口。基于此,首先从南海渔业资源环境特点、南海渔业资源开发利用历史沿革与现状,辨析南海渔业时空格局,指出南海渔业资源环境具有跨越国家界线的互通性、整体性与相互依赖性,且周边国家和地区对南海渔业高度依赖,并已经造成资源环境严重衰退。其次通过对南海渔业冲突和南海渔业资源治理所面临的挑战的梳理,指出引发南海渔业冲突的条件今后很可能更加普遍,亟需南海各方共同面对渔业可持续性危机,而南海地区面临的渔业资源环境退化、系统认知不足、区域协作有限等共性挑战与利益诉求,可成为促进区域合作的纽带。最后以区域渔业资源治理为抓手,提出了构建南海命运共同体的建设思路：从推动绿色水产养殖、增强资源环境修复、深化科研共享等方面开展务实的渔业资源治理合作;在区域、国家、地方层面完善跨尺度的海洋治理措施落实体系,协同提升国家层面的顶层涉海涉渔政策设计,强化地方、私营部门和公民个人在南海区域共建中的作用;从建立健全区域组织和完善区域海洋法制推动构建区域层面合作治理体系。  相似文献

Destabilizing the identity–territory nexus: Rights-based discourse in Sri Lanka’s new political geography     

Margo Kleinfeld 《GeoJournal》2005,64(4):287-295

This paper describes the changing discourses of territory in Sri Lanka and their utility in conflict relations. The primordial homeland has been at the center of Sri Lanka’s armed struggle, in which both Sinhalese and Tamil nationalisms have used claims of ancient and ethnically determined territories to justify their right to self-determination, territorial sovereignty, and armed struggle. This identity–territory nexus based on historical argument has been destabilized in Sri Lanka, however. Scholarly findings suggest that historical linkages between ethnicity and territory in Sri Lanka are highly problematic and are no longer effectual means for adjudicating territorial desires in Sri Lanka and producing stable homelands. I argue that rights-based territorial discourses have emerged to enhance the old historical justifications for territorial authority. New narratives based upon fulfilling or denying human rights have been put to work linking authority to territory based upon moral fitness and unfitness, political legitimacy and illegitimacy, and ultimately, upon which political actor deserves to rule the territorially bound population under its control. The first part of the paper examines historical narratives linking national homelands to identity as well as scholarly work that deconstructs this linkage. In part two, external sovereignty and political legitimacy are discussed as the starting point for understanding how rights-based discourses justify territorial claims. In part three, accusations related to human rights violations are described as an important vehicle for shaming political adversaries, undermining their legitimacy, and making and unmaking territorial claims in Sri Lanka.  相似文献   

高精度距离等比例线法海洋划界模型研究          下载免费PDF全文

彭认灿  董箭  陈轶  郑义东  陈惠荣 《海洋测绘》2009,29(4):14-18

分析表明，目前国内外只对距离等比例线法海洋划界模型作了初步的研究，所建立的模型仍然停留在欧氏平面或地图投影平面上，无法满足海洋划界对分界线点位精度的要求。为改变这种局面，提出并建立了一种全新的基于地球椭球体缓冲区构建技术的高精度距离等比例线法——椭球面距离等比例水线法海洋划界模型。  相似文献

介绍了南海周边国家根据1982年《联合国海洋法公约》精神颁布的海洋法律,并叙述了这些国家的管辖区域主张以及与海洋划界有关的领海基线和基点等方面的问题。指出:南海周边国家之间若要划出专属经济区和大陆架边界线,包括我国在内的所有周边国家政府都应当修正不适宜的划界主张,并在划界原则、理论和方法上趋向一致,为早日划好边界,促进南海地区的经济发展和和平稳定而努力。  相似文献   

Maritime clusters in diverse regional contexts: The case of Canada     

David Doloreux  Richard Shearmur 《Marine Policy》2009

This paper presents the main results of a project on Canada's regional clusters in the maritime industry. The objectives of this paper are twofold: firstly, the driving forces and the development processes of the different maritime clusters in Canada are described. Secondly, the role of cluster policy in promoting maritime competitiveness in Canada and the key institutional and geographic barriers that affect their growth and development are discussed. The empirical work consists of analyses and assessment of three clusters in different provinces in Canada: Quebec, Newfoundland and Labrador, and British Columbia.  相似文献   

论证南海海疆国界线   总被引：2，自引：0，他引：2  

王颖  葛晨东  邹欣庆 《海洋学报(英文版)》2017,36(4):1-12

According to a series of important historical maps,i.e.,the Location Map of the South China Sea Islands,the Nansha Islands,Zhongsha Islands,Xisha Islands,Yongxing Island and Shidao Island,and Taiping Island(archived by the Territorial Administration Division of the Ministry of Interior of Republic of China in 1946),and the Administration District Map of the Republic of China published in 1948,the dashed line surrounding the South China Sea Islands represents China's sea boundary in the South China Sea at that time.It was both connected with,and an extension of,the land boundary of China.At that time the dashed line was used to represent the waters boundaries while the solid line was used to represent the land boundary—a universal method used in maps that was then recognized internationally.The above observation provides historical and scientific evidence of China's sea boundary in the South China Sea that is useful for the international maritime delimitation over the South China Sea area.  相似文献
