试论知识经济时代的地理学

近几年,知识经济这一概念在全世界范围得到迅速传播,引起了社会各界的强烈反响．尽管,对于知识经济时代空竟何时到来,学者们虽有争议,但是大家都不约而同地认为,知识经济这一概念恰当地概括了当今世界经济的特征和发展趋势,知识经济将改变人类社会经济生活的各个方面。     

Local responses to changed circumstances: Coalmining in the market economy in Upper Silesia, Poland

It is argued that the emphasis of much recent research into coalmining has been placed on international and national scale influences which affect coalfields as a whole; change at the intra-coalfield scale has received less attention. After providing a background to events in Poland during communism, attention focuses on developments since 1989, commencing with coalfield-wide influences. There follows an examination of the work of the state body Państwowa Agencja Węgla Kamiennego, which executes government policy at the local level, and whose membership is drawn from the coalfield region. This agency recommends the closure and amalgamation of mines, but otherwise rationalisation measures are left to the seven mining companies and the colliery managers. The restructuring which has been carried out is considered under five heads: organisational change within the collieries, employment, production and technical change, and ecological adjustment. While recognising the importance of the socioeconomic and political environment and geology, there is much evidence to suggest that intra-coalfield patterns are strongly determined by local decision-makers.

三峡库区经济发展评价

当前三峡库区经济发展存在主要产业经济效益低，国有产业亏损大，产业规模小，城镇经济中心作用弱等突出问题．库区开发必需是持久战和持续发展相结合，将库区基础设施建设放在重要地位，搞好资金、行业、所有制之间的优化组合，大力发展第三产业；要准备用几十年的艰苦奋斗，才能赶上全国平均水平．     

关于网络经济的经济增长特征问题的讨论

同传统的大工业经济相比较，网络经济条件下的经济增长特征问题有了新的内容。这就是，影响经济增长的主要因素有质的变化；经济资源得以在全球范围内优化配置；人力资源开发在经济增长中具有决定性作用；集约化成为经济增长的主要方式；信息技术成为经济增长的主要推动力。     

Carrying Capacity of Marine Region in Liaoning Province

Carrying capacity is one of important studies on coordinating development of population,resources,and environment.At present,the researches on it mainly concentrate on the carrying capacity for population and economy,such as the water resources carrying capacity,the land resources carrying capacity,the environment carrying capacity,etc.Based on the related theories and methods,this paper creatively proposed the concept and meaning of carrying capacity of marine region,and formed the appraisal system.According to the developing situation of marine economy of Liaoning Province in recent years,and by employing the method of the state space,this paper also measured the carrying capacity and carrying state of marine region and discussed the sustainable problems of marine economy of Liaoning.The research results show that the carrying state of marine region of Liaoning is in the state of overloading at present,but taking a favorable turn.     

基于扇形筛选法的矢量数据压缩方法

针对具有预测功能的矢量数据压缩方法效率低下的问题,提出一种基于扇形筛选法的矢量数据压缩方法。在预测区域内利用扇形筛选法,能显著减少待选点,从而提高压缩效率。实验结果证明,该方法的效率与改进前方法相比提升了30%~40%。此外,与传统的Douglas-Peucker算法相比,该方法在相同阈值下可以得到更大的压缩比,且在较小阈值下具有更高的计算效率。     

辽宁省低碳经济发展水平评价

构建包含经济系统、能源系统、碳排放系统、技术投入系统和环境系统5个准则层及23个指标的低碳经济发展水平评价体系,基于可变模糊识别模型,分析评价辽宁省低碳经济发展水平。结果显示:辽宁省低碳经济发展水平由2004年的2.87提升到2014年的3.01,由中碳偏高水平提升到中碳发展水平。沈阳、大连、丹东、锦州、营口和葫芦岛的低碳经济发展水平较高;鞍山、抚顺、本溪、盘锦、辽阳及铁岭的低碳经济发展水平较低。在此基础上,运用SBM模型测算辽宁省各市的碳排放效率,其结果与低碳经济发展水平评价值有较大关联。     

Thule Fishing Revisited: The Economic Importance of Fish at the Pembroke and Bell Sites,Victoria Island,Nunavut

Geografisk Tidsskrift—Danish Journal of Geography 110(2):261–278, 2010

In a comprehensive overview of evidence for fishing in the Thule period of the eastern North American Arctic, Whitridge (2001) noted that fish bones are either extremely rare or absent in archaeofaunal samples, despite the fact that artifact assemblages typically contain a variety of fishing implements. In this paper, we present new faunal data from two sites on southeastern Victoria Island, Nunavut, which offer a marked contrast to this pattern. The Pembroke site, located just north of Cambridge Bay, is a small Thule site probably occupied during an early migration into the region. The Bell site, located on the Ekalluk River, is a more substantial site, occupied for a much longer duration during the Thule period. These sites are located in areas devoid of many taxa preferred by Thule peoples, which led the sites' occupants to rely on caribou and fish for much of their winter subsistence. At the Bell site, storage of caribou and fish was critical for winter survival. However, the occupants of the Pembroke site appear to have been unable to acquire sufficient stores during the fall, and therefore relied on fishing through the ice during winter to supplement their inadequate stores. Although both sites indicate a more important economic role for fish than has been recorded on any other eastern Arctic Thule winter site, the use of fish at the two sites differs markedly, adding nuance to archaeologically known Thule subsistence patterns.     

The Econo-techno-social Design of Invasive Animal Management: costs and benefits or beneficiaries and benefactors?

This paper examines invasive animal management institutions, using theories at the interstices of anthropology and geography, to question current approaches to management based on neoclassical and neoliberal economic rationales. I present an analysis of two feral pig management regimes in Far North Queensland, Australia: (i) bounty systems of payment for feral pig control; and (ii) a community-based feral pig trapping program. I show how these management methods reshape important social and cultural processes through their overlapping technological and economic elements. On the basis of this analysis, I propose a conceptual framework for invasive animal management planning that incorporates a beneficiary–benefactor analysis alongside cost–benefit analyses. I argue that ecological-economic theories of pest management may be usefully enhanced by addressing the links between economic and social behaviours.     

在矿产储量管理上应改革沿用的静态工业指标初探

50年代引进前苏联在地勘工作中用静态法制订工业指标、计算矿产储量,为矿山建设提交可供设计利用的矿产储量方面,曾经起到巨大的推动作用。然而,随着改革、开放,上述方法就不能适应市场经济发展的要求,本文试图在剖析静态法制订工业指标、计算矿产储量的四个弊端的基础上,探讨用贸易指标计算矿产储量来取代以往那种用静态法制订工业指标计算矿产储量的管理方法。
