The production and use of fossil fuels and nonrenewable electricity creates many forms of environmental degradation. To reduce degradation, this research suggests an energy strategy based on energy end‐use analysis and regional geography. Energy end‐use analysis and regional geography are used to match renewable energy resources with site‐specific, end‐use needs. Fieldwork conducted within Centre County, Pennsylvania, demonstrates that small‐scale solar, wind, and micro‐hydropower resources could displace a proportion of household electricity use. Such an approach meets energy end‐use needs, while conserving fossil fuels and reducing environmental degradation.  相似文献

Despite the growing practice of community mapping, empirical research remains limited. Extant studies have focused primarily on “counter‐maps” and indigenous maps, leaving many locally produced maps and their authors' perspectives unexplored. This article identifies the mapping process as critical to the definition and understanding of community mapping. It links critical cartography literature to goals of community‐mapping practitioners through themes of inclusion, transparency, and empowerment. The discussion highlights the social construction and practice of “community,” the relationship between maps and power, the definitional difficulties associated with community mapping, and the figurative and literal boundaries that constrain community cartography. Finally, it points to areas for further research and exploration.  相似文献

Abstract

Mental image and place-preference maps of college students in Florida were created through a two-part lesson. The patterns revealed by these maps were linked to students' life experiences, census data on migration and income, and similar studies conducted in other states. Students prefer states with established migration links to Florida and better income/job opportunities. Because the maps could not be created without their input, students were wholly engaged in a lesson that uses concepts in population geography and cartography to fulfill several national geography standards.  相似文献

A fractal can be simply understood as a set or pattern in which there are far more small things than large ones, for example, far more small geographic features than large ones on the earth surface, or far more large-scale maps than small-scale maps for a geographic region. This article attempts to argue and provide evidence for the fractal nature of maps and mapping. It is the underlying fractal structure of geographic features, either natural or man-made, that make reality mappable, large-scale maps generalizable, and cities imageable. The fractal nature is also what underlies the beauty of maps. After introducing some key fractal concepts such as recursion, self-similarity, scaling ratio, and scaling exponent, this article demonstrates that fractal thought is rooted in long-standing map-making practices such as series maps subdivision, visual hierarchy, and Töpfer’s radical law. Drawing on previous studies on head/tail breaks, mapping can be considered a head/tail breaks process; that is to divide things around an average, according to their geometric, topological and/or semantic properties, into the head (for those above the average) and the tail (for those below the average), and recursively continue the dividing process for the head for map generalization, statistical mapping, and cognitive mapping. Given the fractal nature of maps and mapping, cartography should be considered a perfect combination of science and art, and scaling must be formulated as a law of cartography or that of geography in general.  相似文献

Physical geographers are often confronted with the decision of whether to publish in geography or nongeography journals. The present study seeks to quantify the number of articles with a significant hydrology content published in geography versus hydrology journals by physical geographers from 1997 to 2002 using the ISI Web of Knowledge electronic database. Of 690 articles published in the 10 selected geography and hydrology journals during the period of study, over four‐fifths were published in hydrology journals. Based on our interpretation of the data, the comparatively smaller audience in geography and the risk of acquiring fewer citations compels physical geographers to publish in hydrology journals for increased visibility. A critical mass of physical geographers should consider publishing some of their work in physical geography journals to elevate the status of geography in the academy.  相似文献

A proportional shift in where geographer‐climatologists publish has occurred in recent decades. More than 1,500 journal articles published by members of the Association of American Geographers' Climate Specialty Group (CSG) in the period 1989–2005 were examined to determine where geographer‐climatologists are publishing. The analysis showed that members of the CSG cumulatively published at least ten articles in thirty‐seven different journals. No single journal accounted for more than 7 percent of the articles published. Although the absolute number of articles has remained relatively static, geographer‐climatologists published 21 percent of their articles in geography journals in 1989–1997, but only 11 percent in 1998–2005. These publication trends are likely to continue and may influence the status and prestige of geography journals and the discipline of geography.  相似文献

地图是地理学的基本语言,也是空间分析必不可少的工具。但长期以来,地图一直被视为一种客观中立的科学成果。受批判地理学的启发,批判制图学/GIS应运而生,其目标是阐明制图实践中所嵌入的话语、权力关系,挑战地图表征中未经检验却被认为是理所当然的假设。经历40余年的争论与磨合,这一研究领域初现轮廓,批判制图学/GIS大致形成2个研究方向:解构路径主要从制图主体身份和地图知识生产过程2个方面出发,分别剖析制图术与国家治理密不可分的联系及其内在的权力作用机制;建构路径主要借助协作制图和反制图手段以实现地图数据的再生产。国内批判制图学/GIS研究刚刚起步,需要继续吸收批判地理学成果,开展不同历史时期、不同类型地图的解构研究,也需要加强建构路径与解构路径的深度弥合,并面向公众开展更加开放、公正的地图应用研究,将研究成果积极应用于社会实践。  相似文献

能源短缺、利用率低、环境恶化已经成为制约我国经济发展的重要环节。本文运用三阶段DEA模型对中国29个省市2009年的能源效率进行了分析。文章将技术效率分为纯技术效率和规模效率,并利用其数值来分析能源效率,同时,加入环境变量来分析完善上述计算结果。结果表明,在剔除外部因素和环境变量以前规模效率被高估,纯技术效率被低估。大部分省在第三阶段计算出的规模收益是递增的,这说明很多企业规模较小不能体现出规模经济性。从区域上来看则是东部地区的能源效率最高,中部次之,西部最低。针对这一结果,本文给出几点建议:中西部地区应加强合作,发挥各自优势,开发新技术新能源,提高能源利用率,促进经济健康发展。  相似文献

Abstract

Concepts related to alternative map projections can be difficult to explain to students given the diversity and complexity of available projections. Students frequently have trouble understanding how distortions caused by the choice of a projection can affect map readability and comprehension. Programs available for personal computers now provide geography and cartography instructors with a method for interactively educating students concerning the distortions associated with alternative map projections. Such software can be incorporated into laboratory assignments in introductory geography courses or in more advanced courses that deal with map design or thematic cartography.  相似文献

Cultural Globalization,Global English,and Geography Journals   总被引:1,自引:0,他引:1  
In this paper we review the debate on cultural globalization and examine the rise of English as a form of global communication. The implications of these trends for the geographical community are discussed in an analysis of the use of English in geography journals. We note the increasing number of journals published in English, measure the proportion of contributions from non‐English‐speaking countries in English language journals, and note the language practice of selected journals. We conclude that there has been a trend towards linguistic homogenization and raise the question: what are the implications of a geographical discourse dominated by just one language?  相似文献

Health geography in Aotearoa New Zealand (NZ) has had a major impact on international sub‐disciplinary debates. It is timely to celebrate our domestic health geography achievements and alert ourselves to the challenges ahead. This reflection article provides a brief overview of Aotearoa NZ's maturing health geography community and includes the reflections of a panel discussion held during the bi‐annual NZ Geographical Society conference in 2016. We argue that the eclectism of health geography in NZ and beyond is both the sub‐discipline's major strength and challenge.  相似文献

Digital terrain modeling has a micro‐ and nanoscale counterpart in surface metrology, the numerical characterization of industrial surfaces. Instrumentation in semiconductor manufacturing and other high‐technology fields can now contour surface irregularities down to the atomic scale. Surface metrology has been revolutionized by its ability to manipulate square‐grid height matrices that are analogous to the digital elevation models (DEMs) used in physical geography. Because the shaping of industrial surfaces is a spatial process, the same concepts of analytical cartography that represent ground‐surface form in geography evolved independently in metrology. The surface topography of manufactured components, exemplified here by automobile‐engine cylinders, is routinely modeled by variogram analysis, relief shading, and most other techniques of parameterization and visualization familiar to geography. This article introduces industrial surface‐metrology, examines the field in the context of terrain modeling and geomorphology and notes their similarities and differences, and raises theoretical issues to be addressed in progressing toward a unified practice of surface morphometry.  相似文献

ABSTRACT. City maps are among the oldest and most popular forms of cartographic representation, yet urban cartography has received only limited scholarly attention. A review of the early history of city mapping suggests a progression of representational forms from profile to perspective to plan, a progression that parallels urban growth. The history of urban mapping reflects a desire to comprehend the geography of the city for reasons of curiosity and practical necessity, but the map also may become an icon that engenders a sense of pride and belonging, if not allegiance and control. An examination of Chicago maps indicates that, in addition to evolution in representational styles, the subjects of maps change to serve demands of the moment. City maps not only constitute a rich historical archive but also are dynamic agents in urban development. The urban landscape is shaped by cartographic vision.  相似文献

Abstract

Field work in geography often involves an exercise in which the student is required to make some type of map. Although most areas of the United States are well mapped, seldom are extremely large-scale (larger than 1:24,000) relief maps available. A method of contour-line mapping using small contour intervals and a large scale is appropriate in teaching several mapping principles and requires only a few simple tools and the use of elementary mathematics. Percent slope is established at uniform intervals along closely spaced traverses of the area to be mapped. Spot elevations are thus established from which contour lines can be determined. Accuracy in field-data collection and care in cartography will yield a very satisfactory map of terrain characteristics of small areas. Several concepts of maps and mapping are taught through direct student involvement.  相似文献
