California's excellent road system has provided unmatched mobility for most of the state's residents. Recently, however, constraints on construction of high-capacity roads have threatened the future of unrestricted auto use. California's transportation planners have therefore shifted emphasis from expanding the transportation system to increasing its efficiency. No concomitant change has occurred, however, in state legislation or resource allocation. As a result, rather than being an integrated process, transportation planning and implementation are fragmented. This paper examines the origins and implications of this situation and possible remedies for it. 相似文献

Using Action Research to Implement the National Geography Standards: Teachers as Researchers 总被引：1，自引：1，他引：0
《The Journal of geography》2012,111(3):103-111
Abstract Action research is defined as systematic classroom-based inquiry to solve teacher-perceived problems. It has been a component of education, particularly professional staff development, for the past century under several names although geography educators in the United States have rarely used it for this, or any other, purpose. This paper reviews the literature on action research in order to argue for its use in geography education. A preliminary exploration of action research-based professional staff development is described. The results of the project indicate that action research is potentially useful as a way to guide teachers to reflect on their practice. It is argued that geography educators should include it in their repertoire of reform techniques. 相似文献

This paper investigates the historical relationship between the development of marine-based tourism and representations of marine space. Over the past 100 years, the Caribbean Sea has been transformed from a transportation surface connecting exotic ports of call into a commodity itself. Imagined by early travelers as a two-dimensional space to be crossed, the Caribbean has became part of a new tropical marine aesthetic, a three-dimensional spectacle to be actively consumed and conserved. These changing representations of the marine environment as a space of consumption have been paralleled by changes in the relationships between marine and terrestrial political economies. As marine-based tourism has intensified, the balance of power among coastal resource users has shifted. The increasingly conflictive consequences of this shift are illustrated by the case of Soufrière in St. Lucia where new uses of marine space have re-configured social and economic relationships. Soufrière's coastal economy has been transformed and its marine space increasingly politicized as competing representations of the sea have been used to assert conflicting claims to resource access. This paper attempts to elucidate the power of these representations by investigating their historical relationship to the changing role of the Caribbean Sea in the international tourism industry. 相似文献

ABSTRACTThe 21st century has been called the “century of the city” and compounded concerns that current development pathways were not sustainable. Calls for scholarship on urban sustainability among geographers cites strengths in the human-environment and urban subfields that positioned the discipline to make unique contributions to critical research needs. This special issue reflects on the contributions that geographers have made to urban sustainability scholarship. We observe that that integration across human-environment and urban subfields reflects broader bifurcations between social theory and spatial science traditions in geography. Piggy-backing on the rise of sustainability science, the emergence of urbanization science compels geographers to reflect upon the ways in which we are positioned to make unique contributions to those fields. We argue that those contributions should embrace systems thinking, empirically connect social constructs to biophysical patterns and processes, and use the city as a laboratory to generate new theories. 相似文献

Abstract The Geography Department at California State University, San Diego, has initiated a formal internship program for both advanced undergraduate and graduate geography majors. This article presents informational background material on the organization and operation of the program. During the first year of operation, students have interned at various locations, including town, city, and regional planning departments, and state and county environmental and transportation agencies. The program has been an unqualified success with enrollment expanding. Students find that the work/learn experience has a far greater impact than many an hour of professional lecturing. 相似文献

The transportation requirements of an urban area are, in part, a function of its land use pattern. Reducing travel in an urban area by effective land use design appears to be a worthwhile public policy objective. The planning model derived in this article uses as its core the matrix version of the Lowry model developed by Garin. The model allocates basic employment to the zones of an urban area in order to minimize work and service trips. A hypothetical planning problem for Metropolitan Toronto illustrates use of the model. 相似文献

Over the past six years hog farming in North Carolina has undergone a significant restructuring. For most of this century raising hogs was a casual farm activity found throughout the state. During the past decade hog farming has been transformed along industrial-corporate lines. In the process, the swine population has expanded rapidly (exploded) and simultaneously collapsed in geographical bounds (imploded). This paper examines the linkage between the development of the industrial-corporate hog farming regime, the rapid growth in hog populations, and the geographical concentration of hog production in a newly emerging high-density hog production district in the south central area of the Coastal Plain region. 相似文献

This paper reviews the process of transportation construction in China and investigates the developmental and spatial characteristics of transportation patterns. The principles of transportation evolution including stages, structures and orders are systematically analyzed. The investigation shows that China’s transportation construction mode has upgraded from investment-driven scale expansion to uality improvement driven by efficiency and promotion. The rapid growth and development of transportation networks has significantly influenced economic and social activities in time and space. The resulting spatial convergence and dominance have improved distribution, promoting development of the socioeconomic structure. Regional development that has traditionally been based on corridors has changed into a networked mode centered on cities and metropolitan areas. The transportation pattern follows evolutionary principles. China has been moving from a hierarchical structure to a cascade structure. Simultaneously, the socioeconomic pattern has changed from an axis to a hub-and-spoke structure with a preliminary ordered network. As transportation networks grow, China’s functional spatial structure and ordered network will gradually become stabilized and balanced.

Abstract Political geography has long been a major field of interest for geography teachers and students. One of the most interesting areas of political geography is the study of boundaries and boundary zones. In this context, the demilitarized zone (DMZ) as a political separating agent has been one of the most controversial issues in the twentieth century. The demilitarized zone of Vietnam, Korea, and Israel all constitute major zones of tension and friction. The major reason for the instability attending these frictions is that the DMZ's were created by military armistice agreements rather than more conventional political processes. Thus the DMZ's are the product of an unresolved conflict. This geopolitical analysis of the Israel-Syrian DMZ describes how the zone was created and how it functioned between 1949 and 1967. 相似文献

Abstract By the end of this century the Panama Canal will have reached its maximum capacity of 50,000 ship transits a year. If the needs of future inter-oceanic commerce are to be met it is imperative that a new and expanded waterway across the Isthmus of Central America be created. A sea-level type canal would best serve the demands of twenty-first century shipping. Two techniques are feasible for such a project: conventional and nuclear excavation. Each technique boasts of certain advantages over the other, the conventional being safer while the nuclear is faster and cheaper. Five routes have been scrutinized as a potential canal site. Prior to any final determination of either digging procedure or route location, problems such as safety, regional ecology, canal currents, and diplomatic and political agreements must be resolved—with 1985 looming as the latest judicious date to commence excavation. 相似文献

Abstract Country music offers students and instructors of geography a fertile area for explaining many of the concepts and traditions emphasized in the field. This study focuses on the physical, man-land, and spatial traditions of geography and their significance in analyzing a particular style of American country music. During the early part of the twentieth century, bluegrass music originated in Appalachia where man-land relationships were important to the inhabitants. It has since been diffused by the migration of musicians and facilities accommodating the old-time “pickin' and singin'” sound. The purpose of this study is to lend insight to the possibilities of using country music to illustrate the spatial-temporal phases of American culture. 相似文献

Abstract China, despite its failure to modernize in step with Europe's industrial revolution, has a long and rich history of commerical and economic growth, development, and integration. Economic growth and environmental change are presented here, and two dimensions—space and time—are invoked to describe the process as it took place in mainland China. The objectives are to present generalized abstractions of the Chinese earth space and environment within a chronological framework of growth and change in China. Three salient phases of progression are noted: 1) A traditional transition 2) A Western and Japanese influenced Commercial/Industrial transformation 3) A Socialist planned development At each stage of the sequence, significant landscape and environmental changes have been imposed, and these are explored in order to determine key themes and alterations at a local, regional and national scale. Such a sequential model should permit the accurate simplification and increased cross-national understanding of complex phenomena and facilitate presentation of these phenomena in classroom situations. 相似文献

ABSTRACTThe Travelling Stock Route and Reserve (TSR) network is an historical grazing reserve network under threat, where public alarm has continued over the potential sale of reserves. Present debate on the future of the TSRs is often hindered by a lack of data, as knowledge of the historical extent of TSRs is deficient. This paper documents the original extent of the New South Wales TSR network and changes during 1884–2017, and discusses the key drivers of reserve loss since the late nineteenth century. Research using archived literature showed that, in 1884, the New South Wales TSR network comprised 4,414,690?ha. Comparisons of TSR acreage from that time with present estimates revealed that the reserve network has declined by 54% since its inception. Most reductions in TSR area during 1884–2017 have occurred in the Eastern (83%) and Central (82%) regions of the state, where competing land demands are greatest. Technological changes in transport, environmental pressures and economic changes in the grazing industry were identified as key drivers of TSR loss. These findings support concerns over the efficacy of the TSR reserve network, where the extent and impacts of past government decisions to sell off TSRs has been grossly under-estimated. 相似文献

Abstract Geography textbooks represent an underutilized raw material for understanding the society which created them and which, with their aid, “writes” important images for social survival. This paper represents an attempt to examine the images of the Palestinians that are embedded in Hebrew geography textbooks that have been written over the past century during which Zionism has existed. The texts, which were examined with the aid of ideas provided by Thompson (1987) and others, indicate the existence of a wide range of treatments of the Palestinians: ethnocentric, romantic, experiential, anthropological, etc. The spectrum of images is dependent on the historical period in which the text was written and the relations that were created between the Palestinians and Zionism in the Land of Israel. 相似文献

Area studies emerged as the leading tradition in American geography during the second decade of this century, supplanting the earth science tradition. The man-land tradition, reaching its peak during the second and third decades, never became as dominant as did the area studies tradition, based on a classification of the number of articles published, papers presented at annual AAG meetings, doctoral dissertations, and philosophical and methodological pronouncements by noted figures in American geography. 相似文献

Human interactions with the marine environment and pollution hold broad lessons for understanding environmental change. Expanding geographical inquiry beyond its traditional, land-based foci and delving deeper into marine environment and risk issues offers fruitful avenues by which to elaborate and refine our understanding of nature-society relationships. I present a case study of marine petroleum transportation risks in the Straits of Malacca to illustrate the complex history of political and economic processes across a range of scales and shaping the risks in the Straits. The inescapable tension between generalizing global social and environmental processes and recognizing the array of local differences drives ongoing policy debates in the Straits, as it does increasingly for many global environmental problems. 相似文献

Abstract The end of the twentieth century was characterized by a surge of interest in the impact of gender on environmental politics. Many people assert that women have a special relationship with the environment, leading to a link being assumed between women and environmental issuses in development planning. This article analyzes this assertion cross-culturally and, using field data from both North America and the global South as illustration, engages with a long-standing set of debates concerning the relationship between agency, structure, knowledge, and power and the ways in which these relationships have been opera-tionalized and conceptualized. 相似文献

1711-1982年云南雨季早晚序列的重建与夏季风变迁 总被引：1，自引：1，他引：0
According to the textual research into the historical documents dominated by archives yearly, as well as the verification with several other kinds of data, the later or earlier starting time of the rainy seasons in Yunnan during 1711-1982 has been reconstructed. The analysis indicates that there are obvious fluctuations in the starting date of the rainy seasons in Yunnan in a year or years, and long fluctuation on the decadal scale. The rainy season comes earlier in the early 18th century, later in the 19th century and earlier again in the 20th century. This reflects to a certain degree the gradual change of the summer monsoon in Yunnan. There exists an obvious quasi-3 years cycle, which is related to EI-Nino＇s quasi-3 years cycle, and a 11.3-year cycle which is notably related to the 11-year cycle of the solar activity of starting date of the rainy seasons in Yunnan. Meanwhile, the dissertation finds that the EI-Nino is very important to the starting date of the rainy seasons in Yunnan. The starting date of the rainy seasons in Yunnan often comes later or normally in the year of EI-Nino. However, there is an obvious imperfect period in such influence, which in turn may mean that there is a certain fluctuation in the effect of ENSO on Asian summer monsoon. 相似文献
